vim,
The removal and restoration of deteriorated concrete and steel within beams, columns, decks and
adjacent walls will comply with the IRCI Guideline No. 03730 (a copy of which is attached hereto)
or as modified by Engineer as work progresses.
The anticipated work involves the initial demolition, and then the removal, replacement and
restoration of concrete and reinforcement as required. The degree of restoration is currently
unknown; until such time as the initial demolition has begun. s
The anticipated sequence of repairs is as follows:
• Shoring required for repairs of all columns, beams and decks (if required by engineer)
• Removal and restoration of concrete and reinforcement steel within beams, columns and
decks. (ICRI Guideline No. 03730)
o Minor chipping and patching of areas not requiring full depth repairs.
• Applied deck coating.
The following materials are approved for anticipated use in this restoration (see attached
manufacturers specifications):
• Sikacrete 211 Concrete Mix.
• SikaTop 123 PLUS.

The above sequence is general in nature and will be modified as restoration work progresses.
Observations of the initial demolition will determine any required modifications to the above
procedures and materials selected for the final restoration process.
Based on initial visual observations, repairs will not require shoring; however, in the event the
demolition work reveals that shoring will be required, the engineer will instruct the contractor to
shore the area as well as the number of levels required. The instructions given to the contractor will
be submitted to the Building Department with the final close-out documents.
We have been authorized by the Association to work with the contractor during the restoration and,
will inspect work partially completed as well as observe results of the new demolition prior to field
authorizing the repairs to be completed.
The proposed concrete restoration work, except as authorized by the engineer's modified
instructions, will comply with specifications outlined in the IRCI Guideline No. 03730, as well as
the applicable minimum building codes and the applicable fire safety standards as determined by
the local authority in accordance with Chapter 553 and Chapter 633 of the Florida Statutes where
applicable to concrete restoration.

How to Use
Substrate Concrete, mortar, and masonry products.
Surface Preparation Concrete: Remove all deteriorated concrete, dirt, oil, grease, and all
bond -inhibiting materials from surface. Be sure repair area is not less
than 1 in. in depth. Preparation work should be done by high pressure
® water blast, scabbler, or other appropriate mechanical means to obtain
an exposed aggregate surface with a minimum surface profile of t1/8
in. (CSP-7). Saturate surface with clean water. Substrate should be
saturated surface dry (SSD) with no standing water during application.
—A130
Reinforcing Steel: Steel reinforcement should be thoroughly prepared by mechanical clean
to remove all traces of rust. Where corrosion has occurred due to the presence of chlorides,
steel should be high-pressure washed with clean water after mechanical cleaning. For primir
of reinforcing steel use Sika Annatec 110 EpoCem (consult Technical Data Sheet).
Priming For priming of reinforcing steel use Sika Armatec 110 EpoCem (consult Technical Data Shee
Mixing Place 4/5 of 1 gallon water in mixing container. Add Sikacrete 211 while continuing to mi:
Add additional water up to 1 gallon total. Mix to a uniform consistency, maximum 3 min-
utes. Mechanically mix with a low -speed drill (400-600 rpm) and paddle or in appropriate
size mortar mixer or concrete mixer.
Application & Finish Form and pour or pump applications: Pre -wet surface to SSD. Ensure good intimate
contact with the substrate is achieved. To accomplish this, material should be scrubbed [
the substrate or other suitable means should be employed such as vibration of the metal
or pumping under pressure. Vibrate form while pouring or pumping. Pump with a variablt
pressure pump. Continue pumping until a 3 to 5 psi increase in normal line pressure is
evident then STOP pumping. Form should not deflect. Vent to be capped when steady flt
is evident, and forms stripped when appropriate.
Curing As per ACI recommendations for portland cement concrete, curing is required. Moist curl
with wet burlap and polyethylene, a fine mist of water or a water based* compatible curin
compound. Curing compounds adversely affect the adhesion of following layers of morta
leveling mortar or protective coatings: Moist curing should commence immediately after
finishing. Protect newly applied material from direct sunlight, wind, rain and frost.
'Pretesting of curing compound is recommended.
Limitations . Application thickness: Minimum 1 in. (25 mm); Maximum 8 in. (200 Trim)
. Minimum ambient and surface temperatures 45°F (7°C) and rising at time of applicatio
. Using SikaLatex, SikaLatex R or similar products will result in loss of slump and slump
retention. Field tests for suitability are strongly recommended.
Caution

eye irritant. Avoid contact. Dust may cause respiratory tract irritation. Avoid breathing dus
Use only with adequate ventilation. May cause delayed lung injury (silicosis). [ARC lists
crystalline silica as having sufficient evidence of carcinogenicity in laboratory animals arc
limited evidence of carcinogenicity in humans. NTP also lists crystalline silica as a suspe.
carcinogen. Use of safety goggles and chemical resistant gloves is recommended. If PE
are exceeded, an appropriate, NIOSH approved respirator is required. Remove contami-
nated clothing.
First Aid In case of skin contact, wash thoroughly with soap and water. For eye contact, flush imm
diately with plenty of water for at least 15 minutes, and contact a physician. For respiratc
problems, remove person to fresh air.
Clean Up in case of spillage, scoop or vacuum into appropriate container, and dispose of in accor-
dance with current, applicable local, state and federal regulations. Keep container tightly
closed and in an upright position to prevent spillage and leakage.

surface. Be sure repair area Is not less than 1/8 inch in depth. Preparation work should be done by high pres-
sure water blast, scabbler, or other appropriate mechanical means to obtain an exposed aggregate surface
with a minimum surface profile of ±1116 in. (CSP-5) Saturate surface with clean water. Substrate should be
saturated surface dry (SSD) with no standing water during application.
Reinforcing Steel: Steel reinforcement should be thoroughly prepared by mechanical cleaning to remove all
traces of rust. where corrosion has occurred due to the presence of chlorides, the steel should be high-pressure
washed with clean water after mechanical cleaning. For priming of reinforcing steel use Sika® Armatece 110
EpoCem (consult Technical Data Sheet).
Priming
Concrete Substrate: Prime the prepared substrate with a brush or sprayed applied coat of Sika® Armatec
0110 EpoCem (consult Technical Data Sheet). Alternately, a scrub coat of Sika Top 123 can be applied poor
to placement of the mortar. The repair mortar has to be applied Into the wet scrub coat before it does.
Mixing
Pour Component'A' into mixing container. Add Component'B'while mixing continuously. Mix mechanically with
a low -speed drill (400- 600 rpm) and mixing paddle or mortar mixer. Mix to a uniform consistency, maximum 3
minutes. Manual mixing can be tolerated only for less than a full unit. Thorough mixing and proper proportion-
ing of the two components is necessary.
Application
SikaTope 123 PLUS must be scrubbed into the substrate, filling all pores and voids. Force material against
edge of repair, working toward center. After filling repair, consolidate, then screed. Material may be applied in
multiple lifts. The thickness of each lift, not to be less than 1/8 inch minimum or more than 1.5 inches maximum.
Where multiple lifts are required score top surface of each lift to produce a roughened surface for next lift. Allow
preceding lift to reach final set, 30 minutes minimum, before applying fresh material. Saturate surface of the
lift with clean water. Scrub fresh mortar into preceding lift. Allow mortar or concrete to set to desired stiffness,
then finish with wood or sponge float for a smooth surface.
Tooling & Finishing
As per ACI recommendations for Portland cement concrete, curing is required. Moist cure with wet buriap
and polyethylene, a fine mist of water or a water based', compatible curing compound. Curing compounds
adversely affect the adhesion of following lifts of mortar, leveling mortar or protective coatings. Moist curing
should commence immediately after finishing. If necessary protect newly applied material from direct sunlight,
wind, rain and frost.
Limitations a Application thickness: Minimum 1/8 inch (3 mm). Maximum in one lift - 1.5 in. (38 rum).
Is Minimum ambient and surface temperatures 45°F (7°C) and rising at time of application.

Sika FerroGard 903
Sika FerroGard° 903
Penetrating, corrosion inhibiting, impregnation
coating for hardened concrete
Descriptlon
Sika FerroGard 903 is a corrosion inhibiting impregnation coating for hardened concrete surfaces. It is
designed to penetrate the surface and then to diffuse in vapor or liquid form to the steel reinforcing bars
embedded in the concrete. Sika FerroGard 903 forms a protective layer on the steel surface which inhibits
corrosion caused by the presence of chlorides as well as by carbonation of concrete.
How It Works
Sika FerroGard 903 is a combination of amino alcohols, and organic and Inorganic inhibitors that protects
bath the anodic and cathodic parts of the corrosion cell. This dual action effect dramatically delays the initia-
Lion of corrosion and greatly reduces the overall corrosion activity.
Sika FerroGard 903 protects the embedded steel by depositing a physical barrier in the form of a protective
layer on the surface of the steel reinforcement. This barrier inhibits corrosion of the steel.
Where to use
Sika FerroGard 903 is recommended for all steel -reinforced, prestressed, precast, post tensioned or marine
concrete. Use of Sika FerroGard 903:
. SteeHeinforced concrete, bridges and highways exposed to corrosive environments (deicing salts, weathering)
. Building facades and balconies
■ Steel -reinforced concrete in or near a marine environment
. Parking garages
. Piers, piles, and concrete dock structures
. As part of Sika's system approach for buildings and civil engineering structures
Advantages
Sika FerroGard 903 offers owners, specifiers, port authorities, DOTS, and engineers, a new technology in
corrosion inhibition that can easily be applied to the surface of existing concrete to extend the service life of
any reinforced concrete structure.
■ Protects against the harmful effects of corrosion by penetrating the surface of even the most dense con-
crete and diffusing to the steel to inhibit corrosion.
. Enhances the durability of reinforced concrete.
. Does not require concrete removal.
. Environmentally sound.
. Does not contain calcium nitrite.
■ Easily applied by either spray or roller to all existing reinforced concrete.
■ Can be applied to reinforced concrete that already exhibits corrosion.
. Adds additional benefits when used prior to protective coatings in concrete restoration systems.
■ Water based for easy handling and application.
. Not a vapor barrier; allows vapor diffusion.
. FerroGard has been proven effective in both laboratory (ASTM G109/Cracked Beams) and field analysis.
. ANSUNSF Standard 61 potable water approved
Coverage
For normal concrete, application is 200 ft.'/gal. each coat. A minimum of two coats is always recommended.
For dense concrete, application may exceed 300 ft 2/gal. Therefore, more than two coats may be required
to achieve the total application rate: 100 tt.21gal.
Packaging
5 gallon pails with spout, 55 gallon drums.
How to Use
Surface Preparation
Before applying Sika FerroGard 903 be sure the surface Is clean and sound. Remove all dirt, dust, oil,
grease, efflorescence or existing coatings from concrete surface by steam cleaning, waterblasting or slightly
® sandblasting. Allow concrete surface to dry prior to application of Sika FerroGard 903. The dryer the surface
the beherthe penetration and effectiveness.
Test Methodanstitute:
1. Cracked Concrete Beam Test (adapted from ASTM G109).
2. Secondary Neutron Mass Spectroscopy (SNMS) / Institute for Radiochemistry, Karlsruhe (Germany), Prof.
Dr. J. Goschnick.
3. X-ray Photon Spectroscopy (XPS) and Secondary Ion Mass Spectroscopy (SIMS) / Brundle and Associ-
ates, San Jose, CA and University Heidelberg (Germany), Prof. M. Grunze.
4. Performance of Corrosion Inhibitors in Practice, Gmeme Jones, C-Probe Technologies Ltd., 2000.
Application Sika FerroGard 903 is applied by roller, brush or spray on concrete surfaces. When spraying, use a conven-
fional airless spray system or hand -pressure equipment. A minimum of two coats is always recommend-
ed. Dense substrates may require more coats. Waiting time between coats of Sika FerroGard 903 is at least
1 hour. Allow a minimum of one day to allow Sika FerroGard 903 to dry and penetrate.
When Sika FerroGard 903 is used prior to the application of a repair mortar, concrete overlay, protective
coating, Sikafioor system or any other application, care must be taken to remove any residue remaining on
the surface from the application of Sika FerroGard 903. Clean the substrate In such a manner (i.e. push the
water in one direction away and off from the surface to be overcoated) to completely remove any residue.
Horizontal surfaces require pressure washing (2,000 psi minimum) to remove the residue. Vertical surfaces
may be rinsed with water or pressure washed. The use of Sika Arrnatec 110 EpoCem as a bonding agent
prior to the application of repair mortars or concrete overlays is suggested. Drying times depend on envi-
ronmental conditions, absorbency of the substrate and maximum recommended moisture content for the
subsequently applied system.
Limitations aa Minimum ambient and substrate temperatures 35°F.
■ Do not apply when temperature Is expected to fall below 35°F within 12 hours.
. If the applied surfaces will be submerged after the application of Sika FerroGard 903, a waterproofing
coating must be applied prior to submersion.
■ Substrate should be as dry as possible prior to the application.
. Protect glass, wood, brick, galvanized steel, copper and exposed aluminum during the application.
. Maximum chloride content of concrete structures intended to be treated with Sika FerroGard 903 is 6lbs./y'
(measured at the level of the reinforcing steel). For levels up to 10 Ibs./ya, consult technical service.
Caution Irritant - Skin and eye irritant. Vapors may cause respiratory tract irritation. Use only with adequate ventila-
tion. Use of safety goggles and chemical resistant gloves is recommended. Remove contaminated cloth-
ing.
First Aid In case of skin contact, wash thoroughly with soap and water. For eye contact, flush immediately with plenty
of water for at least 15 minutes; contact physician immediately. For respiratory problems, remove person to
fresh air. Wash clothing before re -use.
Clean Up In case of spills or leaks, wear suitable protective equipment, contain spill, collect with absorbent material,
and transfer to a suitable container. Ventilate area. Avoid contact. Dispose of in accordance with current,
applicable local, state, and federal regulations.. m

How to Apply
Surface Preparation
1. Substrates must be sound and level and the
surface free from protrusions, large pores,
honeycombs, gaping cracks, and ridges. Concrete
substrates should be cured 28 days before Flextight"
application.
2. Sandblast or waterblast substrates to remove all
traces of water repellents, bitumen, form oils, grease,
paint, and other foreign matter from substrate that
could act as a hondbreaker.
3. Any edges must be rounded. Form coves with
regular site -mixed mortar and round to a minimum
radius of 1-1/2" (38 mm).
Mixing
1. Rextight" is supplied in precisely proportioned
units ready for mixing. When using Flextight" in
cooler climates or if a thicker consistency is desired,
reduce the amount of PartA (liquid) in the mixture by
approximately 1 quart (0.9 Q.
2. Precondition material to 700 F±5° (210 C+20)
for easier mixing and application.
3. Slowly add Part B (powder) to Part A while mixing
with a 3/4 inch drill and mixing paddle.
4. Mix to a uniform, smooth, lump -free consistency.
If a looser consistency is desired, add the remaining
portion of Part A liquid. Overmixing may entrap air.
5. Mix for 3 — 5 minutes while blending components
and 1 — 2 minutes after all components have been
blended.
6. The pot life of Flextight" is approximately
30 — 90 minutes depending on ambient conditions.

Application
1. The substrate must be saturated surface -dry
(SSD) with no standing water.
2. Flextight" is applied only to the positive side
(source of moisture) of the substrate in 1 or 2 void -
free coats. Allow 24 hours before second coat.
Thoroughly work the material into the substrate.
Make sure the rounded edges are fully coated. Apply
at 80 wet mils, using a 1/8" (3 mm) square -notched
trowel, yielding 60 dry mils (1/16" or
1.6 mm).
3. Embed fiberglass tape wherever dissimilar
materials join. Also treat surface cracks less than
1/8" (3 mm) wide and areas where underiayment
panels meet.
4. In most cases,1 coat is sufficient without
reinforcing mesh. If reinforcement is necessary,
embed an appropriate mesh into the still -wet first
coat and use a trowel to work the material up and
through the mesh until it is completely embedded.
Material that is too thick is subject to drying or
shrinkage crocking. Be certain to cover all
reinforcement material.
5. Smooth over with the flat trowel edge, creating a
smooth, void -free membrane.
Curing Time
1. Prevent premature drying of the green application
and protect it from extreme heat, direct sunlight,
wind, rain, and frost for at least 3 days. (Curing time
varies with humidity, temperature, and substrate
porosity.)
2. Tile can be applied after 3 days.
3. Do not allow surface to become wet before
curing is complete. Protection boards may be needed
to avoid puncturing membrane while installing tile.
Clean Up
Wash tools with water immediately after use. Cured
material may only be removed mechanically.
For Best Performance
• Do not apply at temperatures below 40' F (40 C)
or above 90' F (32• Q.
• Do not dilute with water.
• Do not use additives of any kind.
• Do not apply thicker than 1/16" (1.6 mm).
• Do not over trowel.
• Use caution under extremely hot or windy
conditions; they will shorten the pot life and
reduce trowelability. Call Technical Service for
recommendations.
• Flextight7 is not a vapor barrier.
• This product is not recommended for application
over lauan, presswoods, particle board, masonite,
chipboard, plywood, asbestos board, or any other

• Allow coating to harden sufficiently (not less than
3 days) before tiling over it.
• Do not puncture membrane while setting tiles.
• Concrete substrates should be cured 28 days
before Flextight" application.

HOW TO APPLY
SURFACE PREPARATION
CONCRETE
1.Concrete must be fully cured (28 days),
structurally sound, clean and dry (ASTM D
4263). All concrete surfaces (new and old)
most be shot blasted to remove previous
coatings, laitance and all miscellaneous surface
contamination and to provide profile for proper
adhesion. Abrasive shot blasting must occur
after concrete repair has taken place. Acid -
etching is not permitted. Proper profile should
be a minimum of ICRI CSP-3 (as described in
ICRI document 03732.)
2.Repair voids and delaminated areas with BASF
branded cementitious and epoxy patching
materials. For application when fast -turn repairs
are required, MasterSeal M 265 can be used
to repair patches up to 1" (25 mm) in depth.
Please refer to Technical Service for proper
application techniques.
3.All units must be applied within the
specified pot life.
SURFACE PRE -STRIPING AND DETAILING
1.For nonmoving joints and cracks less than Y,6"
(1.6 mm) wide, apply primer when required,
followed by 25 wet mils (0.6 mm) pre -striping of
MasterSeal M 200. MasterSeal M 200 must be
applied to fill and overlap the joint or crack 3"
(76 mm) on each side. Feather the edges.
2.Dynamic cracks and joints Y,6" (1.6 mm) and
greater wide must be routed to a minimum of
%4 by Ya" (6 by 6 mm) and cleaned. Install bond
breaker tape to prevent adhesion of sealants
to the bottom of joint. Prime joint faces
only with MasterSeal P 173 (see Form No.
1017962). Fill joints deeper than (6 mm)
with appropriate backer rod and MasterSeal
SL 1-/SL 2- (slope grade or self -leveling) or
MasterSeal NP 1'/NP 1'" sealants (see Form
Nos.1017903 and 1017911). For cracks,
sealant should be flush with the adjacent
concrete surface. For expansion joints, sealant
should be slightly concave.
3.Sealed joints 1" (25 ram) or less can be coated
over with MasterSeal Traffic 1500. Expansion joints
exceeding 1" (25 mm) wide should not be coated
overwith MasterSeal Traffic 1500 so that they can
perform independently of the deck coating system.
Technical Data Guide
MasterSeal° Traffic 1500
a.Cut a llA by 1a" (6 by 6 rum) keyway into the
concrete where the coating system will be
terminated if no wall, joint, or other appropriate
break exists. Fill according to instructions on
cracks and joints over %e" (1.6 mm) wide.
5.Form a sealant cant into the corner at the
junction of all horizontal and vertical surfaces
(wall sections, curbs, columns). Prime with
MasterSeal P 173 and apply a Ya-1" (13-25
mm) wide bead of MasterSeal NP 1 or MasterSeal
NP2 sealants. Tool to form a 450 cant.
e.ln locations of potential high movement, such
as wall and slab intersections, apply 25 wet
mils (0.6 mm) of MasterSeal M 200 and embed
MasterSeal 955.
METAL SURFACES
1.Remove dust, debris, and any other
contaminants from vent, drain -pipe and post
penetrations, reglets and other metal surfaces.
2.Clean these surfaces to bright metal and prime
immediately with MasterSeal P 173.
3.Provide appropriate cant with MasterSeal NP1,
NP 2 or CR 195 sealant to eliminate 90' angles.
PLYWOOD
1.AII plywood must be smooth -faced, APA-
stamped and exterior grade. Construction must
conform to code, but plywood must not be less
than 15A2" (12 mm) thick. Plywood spacing and
deck construction must follow APA guldelines.
2.Surtaces must be free of contaminants. Priming
is not necessary on clean, dry plywood.
s.All seams must be caulked with MasterSeal
NP 1 or MasterSeal NP 2 sealants (see Form
Nos.1017906 and 1017911). Pre-shlpe 4-0"
(102-152 mm) wide with 25 wet mils (0.6 mm)
of M 200. Reinforce all seams between plywood
sheets and between flashing and the plywood deck
by embedding MasterSeal 995 into the pre -striping.
APPLICATION OF PRIMER
PRIMER
NOTE: When primer is required an a job, follow
these steps. When applying Traffic 1500 without
using a primer, proceed to Application.
, �' � IN 01 W16 12 IF (1, MY
1.After thoroughly vacuuming the surface, apply
MasterSeal P 222 or P 220 to all the properly
prepared deck surfaces at the rate of 200-250
ft2/gal (4.9-6.1 ma/Q. Using a roller pan and
a short- to medium -nap roller cover, force
the primer Into pores and voids to eliminate
pinholes. Do not apply over pre -striping. Use
only solvent -resistant tools and equipment.
2.Allow primer to dry until tack -free. M 200 must
be applied the same working day.
MASTERSEAL M 200
t.All preparatory work most be completed before
application begins. Be certain the substrate is
clean, dry, stable and properly profiled. Sealants
and pre -striping should be propedy cured. Apply
the base, mid and finish coats with a properly sized
squeegee to arrive at the required mil thicknesses.
2.The best method to ensure the proper wet film
thickness is the use of a grid system. Divide the
surface to be coated into grids and calculate the
square footage of each. Refer to the coverage
chart to determine the quantity of MasterSeal
Traffic 1500 needed for each grid to arrive at
the required mil thicknesses. For example, one
pail of MasterSeal M 200 will cover an area
approximately 300 ft2 (28 ml, or a grid 30 by
10 It (9 by 3 m) at 25 wet mils (0.6 rum). The
mil thickness of all coats can also be verified by
the use of a wet -mil thickness gauge.
3.Apply MasterSeal M 200 25 wet mils thick (0.6
mm) using a proper notched squeegee to entire
deck surface, and back roll, overcoating the
properly prepared cracks, joints and flashings. For
sloped areas, use slope -grade MasterSeal M 200.
Do not coat expansion joints over 1" (25 mm) wide.
4.Allow coding time of overnight (16 hour minimum).
Slightly extend the curing time in cool or dry
weather conditions. The surface of MasterSeal
M 200 should have a slight tack. If the coating
has been exposed for a prolonged period, consult
Technical Service for recommendations.
APPLICATION METHODS OF SYSTEMS
MasterSeal Traffic 1500 can be installed in
several configurations, depending upon the
degree of traffic to which the system is exposed.
In areas of extreme traffic (turning lanes, pay
booths, entrances and axis). apply the Extra
Heavy -Duty Traffic System. The following
summary briefly describes each configuration.

7.Portions of the membrane that exhibit wear are
considered a maintenance item, and are not
considered a warrantable item.
2.Surfaces may be cleaned with commercial
detergents. BASF recommends that a
maintenance agreement be established
between the owner and applicator.
s.Periodic inspection and repair of damaged
surfaces will greatly prolong the performance
and life of the system.
4.Remove all sharp debris such as sand, gravel
and metal on a regular basis to avoid damage
to the coating.
e.When removing snow, avoid the use of metal

About ICRI Guidelines
The International Concrete Repair -Institute (ICRI)
wasfounded to improve the durability ofconcrete
repair and enhance its value for structure owners.
The identification, development, andpromotionof
the most promising methods and materials are
primary vehicles for accelerating advances in
repair technology Working through a variety of
forums, ICRI members have the opportunity to
address these issues and to directly contribute to
improving the practice of concrete repair.
A principal component of this effort is to make
carefully selected information on important repair
subjects readily accessible to decision makers.
During the past several decades, much has been

_I
1.0 Introduction
This guideline provides owners, design profes-
sionals, contractors, and other interested parties
with a recommended practice for the removal of
deteriorated concrete caused by the corrosion of
reinforcing steel, including the preparation of the
removal cavity to provide a clean sound surface
to bond a repair material.
This guideline outlines removal geometry,
configuration, removal process, edge preparation,
reinforcement repair, surface preparation, and
inspection prior to placing a repair material. An
engineer should evaluate the impact of concrete
removal on structural capacity prior to performing
concrete removal and repair. The repair methods
involve saw cutting and concrete removal using
impact tools, hydrodemolition, and other removal
techniques. Special caution should be taken to
locate and avoid cutting or damaging embedded
reinforcing bars, prestressing strands, post -
tensioning tendons, or electrical conduits. Cutting
into these items can be life threatening and may
significantly affect structural integrity.
This guideline also contains a discussion of
concrete removal and preparation for the repair
of columns where the concrete is in compression.
Special consideration must be given to the repair
of concrete in compression as the load -carrying
capacity of the element may be permanently
compromised during the concrete removal and
preparation process.
While the procedures outlined herein have
been used to successfully remove concrete and
prepare the removal cavity on many projects, the
requirements for each project will vary due to
many different factors. Each project should be
evaluated individually to ascertain the applicability
of the procedures described herein. Refer to ACI
506R-05, "Guide to Shotcrete" for surface prepar-
ation prior to shotcrete application.
2.0 Definitions
Anodic ring effect: Corrosion process in which
the steel reinforcement in the concrete surrounding
a repaired area begins to corrode preferentially
to the steel reinforcement in the newly repaired
area (sometimes referred to as the halo effect).
Bruised surface (micro -fracturing): A surface
layer weakened by interconnected microcracks
in concrete substrates caused by the use of high -
impact, mechanical methods for concrete
removal, and surface preparation; fractured layer

typically extends to a depth of 0.13 to 0.38 in.
(3 to 10 mm) and, if not removed, frequently
results in lower bond strengths as compared with
surfaces prepared with nonimpact methods.
Carbonation: The conversion of calcium ions
in hardened cementitious materials to calcium
carbonate by reaction with atmospheric carbon
dioxide. Carbonation reduces the pH of the
concrete and its ability to protect reinforcing steel
and embedded metal items from corrosion.
Chloride contamination: Contamination of
concrete with chloride ions commonly used in
deicing salts and accelerating admixtures such as
calcium chloride and sodium chloride. Chloride
contamination above the threshold for corrosion
can result in corrosion of the reinforcing steel.
Chloride threshold: The amount of chloride
required to initiate steel corrosion in reinforced
concrete under a given set of exposure conditions;
commonly expressed in percent of chloride ion
by mass of cement.
Corrosion: Degradation of concrete or steel
reinforcement caused by electrochemical or
chemical attack.
Microcrack: A crack too small to be seen with
the unaided eye.
Tensile pulloff test: A test to determine the
unit stress, applied in direct tension, required to
separate a hardened repair material from the
existing concrete substrate. The test may also be
used to determine the maximum unit stress that
the existing concrete substrate is capable of
resisting under axial tensile loading and the near -
surface tensile strength of a prepared surface
(refer to ICRI Technical Guideline No. 210.3-
2004 (formerly No. 03739] and ASTM C1583).
Substrate: The layer immediately under a
layer of different material to which it is typically
bonded; an existing concrete surface that receives
an overlay, partial -depth repair, protective coating,
or some other maintenance or repair procedure.
3.0 Exposure of
Reinforcing Steel
The practice of completely removing the concrete
(undercutting) from around the corroded
reinforcement, no matter what degree of corrosion
is found, is key to achieving long -tern performance
of surface repairs. In most cases, complete
removal of the concrete from around the
reinforcing steel is the best practice, where
protection of the reinforcing steel within the

\\Y�i
repair cavity is achieved by providing a uniform
chemical environment around the reinforcing
steel. Ifnoncorroded reinforcing steel is exposed
and the concrete is chloride contaminated,
removal of the concrete around the reinforcing
should occur or other corrosion -reducing means
should be considered. Reinforcing steel partially
embedded in chloride -contaminated concrete is
susceptible to future accelerated corrosion.
If, for structural reasons, the concrete cannot
be completely removed from around the corroded
reinforcing steel or if a corrosion inhibiting
system is notused, the repairmay be compromised
due to continued corrosion. If there is a potential
trade-off between durability and structural
capacity, structural capacity should always take
priority. When reinforcing steel is not fully
exposed through the concrete removal and
preparation process, alternative corrosion inhib-
iting systems should be considered. These
systems may include use of corrosion inhibitors,
sacrificial anodes, or cathodic protection.
4.0 Anodic Ring
(Halo) Effect
The existing concrete surrounding a repair area
in chloride -contaminated or low pH reinforced
concrete is susceptible to accelerated corrosion.
This is due to the electrical potential differential
between the chloride contaminated or low pH
existing concrete and the chloride -free or
high pH repair material. This anodic ring effect
can result in accelerated corrosion of the
surrounding reinforcing steel leading to future
concrete deterioration. To assess existing concrete
conditions beyond the repair area, chloride
content and pH of the concrete at the level of the
reinforcing steel should be determined. Where
the chloride content exceeds the threshold level
for the initiation of corrosion or where the
reinforcing steel is susceptible to corrosion as a
result of carbonation, a corrosion inhibiting
system should be considered to minimize future
corrosion. Other measures may also be considered,
such as the application of sealers and coatings, to
slow the corrosion process. In severely chloride -
contaminated or carbonated concrete, the
complete removal and replacement of the
contaminated concrete at and beyond the repair
area may be necessary to provide a successful
long-term repair.
5.0 Removal
Geometry
Examples of the removal geometry for several
different types of reinforced concrete elements
are shown in Fig. 5.1 through 5.6. Repairs may
be located on horizontal, vertical, and/or overhead
surfaces. The removal in Fig. 5.5 and 5.6 is for
columns where the removal will not affect the
structural capacity of the column. Removal of
concrete within the reinforcing or to expose the
reinforcing (concrete in compression) is a special
condition and is discussed in Section 10.

6.0 Configuration
of Repair Area
Deteriorated and delaminated concrete should be
located and marked prior to starting the removal
process. Delaminated concrete can be located using
sounding or other suitable techniques. The repair
area should extend a minimum of in. (152 mm)
beyond the actual delaminated concrete. Note that
during concrete removal, repair areas can grow
in size beyond the areas identified due to incipient
delaminations that are not readily identifiable
by sounding. Repair configurations should be
kept as simple as possible, preferably square or
rectangular with square comers (Fig. 6.1). This may
result in the removal of sound concrete. Reentrant
corners should be minimized or avoided, as they
are susceptible to cracking.

7.1 Exposing and
Undercutting of
Reinforcing Steel
Remove concrete from the marked areas and
undercut exposed reinforcing steel (Fig. 7.1) using
impact breakers, hydrodemolition, or another
suitable method. Undercutting will provide
clearance under the reinforcing steel for cleaning
and full bar circumference bonding to the repair
material and the surrounding concrete. Bonding

the repair material to the full circumference of the
reinforcing steel will secure the repair structurally.
Provide a minimum of 0.75 in. (19 mm) clearance
between exposed reinforcing steel and surrounding
concrete or 0.25 in. (6 mm) larger than the coarse
aggregate in the repair material, whichever is
greater. Sound concrete may have to be removed
to provide proper clearance around the reinforcing
steel. If impact breakers are used for partial depth
concrete removal, the breaker should not exceed
3016 (12 kg). A 15 lb (7 kg) breaker is preferred

Fig. 7.3: Abrasive blasting to clean

to minimize damage to the substrate, reinforcing
steel, and surrounding concrete.
Concrete removal should extend along the
reinforcing steel until there is no further delam-
ination, cracking, or significant corrosion and the
reinforcing steel is well bonded to the surrounding
concrete. Care should be taken to avoid significant
and sudden changes in the depth of concrete
removal, as the repair material is more susceptible
to cracking at these locations.
If noncorroded reinforcing steel is exposed
during the removal process, care should be taken
to not damage the bond to the surrounding
concrete. If the bond between the reinforcing
steel and concrete is broken, undercutting of
the reinforcing steel is required.
Remove all deteriorated concrete and additional
concrete as required to provide the proper
configuration and/or the minimum required
thickness of repair material as required by the
manufacturer of the repair material and/or the
project specifications.
7.2 Preparation of the
Repair Perimeter
The perimeter of the repair area should be saw
cut 0.75 in. (19 mm) deep to provide a vertical
edge (Fig. 7.2) for the repair material. This will
avoid featheredging of the repair material.
Depending on the repair material selected, the
depth of the existing reinforcing and the
manufacturer's recommendations, a saw cut depth
less than 0.75 in. (19 mm) deep may be sufficient.
Care should be taken to avoid cutting the existing
reinforcing steel.
7.3 Cleaning of the
Concrete Surface and
Reinforcing Steel
The use of high -impact, mechanical methods to
remove deteriorated concrete will result in a
surface layer weakened by interconnected micro -
cracks in the concrete substrate. The fractured
(bruised) layer can extend to a depth of 0.125 to
0.375 in. (3 to 10 mm) into the resultant concrete
substrate and may result in reduced bond strength.
Remove the bruised layer and bond -inhibiting
materials such as dirt, concrete slurry, and loosely
bonded concrete by oil -free abrasive blasting
(Fig. 7.3) or high-pressure water blasting. The
4-310.1R-2008 GUIDE FOR SURFACE PREPARATION FOR THE REPAIR OF DETERIORATED CONCRETE RESULTING FROM REINFORCING STEEL CORROSION
r it
saw -cut edge of the repair area should also be
blasted to roughen the polished vertical surface
caused by the saw -cutting.
All concrete, corrosion products, and scale
should be removed from the reinforcing steel by
oil -free abrasive blasting or high-pressure water
blasting. Verify that the reinforcing steel and
concrete surface are free from dirt, oil, cement
fines (slurry), or any material that may interfere
with the bond of the repair material. Inspect the
repair cavity to verify that all delaminations and
deterioration have been removed. If hydro -
demolition is used, cement fines (slurry) must be
completely removed from the repair surface. A
tightly -bonded light rustbuild-up on the reinforcing
surface is usually not detrimental to bond. If a
protective coating is applied to the reinforcing
steel, follow the coating manufacturer's recom-
mendations for steel surface preparation.
8.0 Inspection
and Repair of
Reinforcing Steel
Loose reinforcement should be secured in its
original position by tying to secure bars or by
other appropriate methods to prevent movement
during placement of repair material.
If reinforcing steel has lost cross -sectional
area, a structural engineer should be consulted.
Repair reinforcing steel by either replacing the

damaged/deteriorated steel or placing supple-
mental reinforcing steel in the affected section
(Fig. 8.1). Supplemental reinforcing steel may be
lap -spliced or mechanically spliced to existing
reinforcing steel. The supplemental reinforcing
steel should extend (lap length) beyond the
damaged/deteriorated area in accordance with
ACI 318, "Building Code Requirements for
Structural Concrete."
9.0 Final Surface
Inspection
Immediately prior to placing the repair material,
inspect the repair cavity to verify that all bond -
inhibiting materials (dirt, concrete slurry, loosely
bonded aggregates, or any material that may
interfere with the bond ofthe repair material to the
existing concrete) have been removed. If bond -
inhibiting materials are present, the repair cavity
should be recleaned as previously described.
To verify the adequacy of the prepared
concrete surface and completeness of bond -
inhibiting material removal, a tensile pulloff test
(ICRI Technical Guideline No. 210.3-2004 or
ASTM C1583) should be considered to evaluate
the bond strength capacity and tensile strength of
the existing concrete substrate. This test may also
be performed after the repair is complete. The
pulloffstrength requirement should be established
by the engineer and included as a performance
specification for the repair.

Undercutting of reinforcement is a best practice
in tensile zones of concrete. In columns, the
primary loading condition is compression. From
a design perspective, the concrete section
contained within the reinforcing cage is considered
to carry the compressive loads (Fig. 10.1). The
concrete outside ofthe reinforcement is considered
as protective concrete cover for fire and corrosion
protection of the reinforcement. Removing the
concrete within the column reinforcing steel
(Fig. 10.2) can greatly increase the compressive
stress in the reinforcing steel and the remaining
concrete. Upon concrete removal, compressive
load paths redistribute around the repair
(deteriorated) sections (Fig. 10.3). Depending on
the size of the concrete removal area behind the
column steel, buckling of the column vertical
reinforcing bars can occur. In the majority of
cases, shoring systems will not unload the
compressive stress in the column section.
When new repair material is placed in the
prepared area, the new material cures and most
materials undergo drying shrinkage, which results
in the new material being put into a tensile stress
state. The new material will not carry compressive
loads until the original concrete compresses further,
forcing the repair material into compression. If
further compression is beyond the capacity of the
existing concrete, failure of the column may
occur. This key concept affects the concrete
preparation process. In normal concrete repair
(other than columns), removal of the concrete
surrounding the corroding reinforcement (also
known as undercutting) is a normal and necessary
process to provide for a long-term durable repair.
To remove concrete around vertical reinforcing
steel in a column (removing concrete inside the
reinforcing bar cage) can cause the remaining
concrete and/or reinforcement in the column to
become overstressed. From a structural point of
view, this condition may not be desirable. If
concrete is to be removed inside the reinforcement
cage, a qualified structural engineer should
determine the impact of the repair on potential
reinforcement buckling and overall structural
capacity of the column. Note that the discussion
in this section is also applicable in concept to
compression zone portions of other structural
members such as beams, slabs, and walls (with
or without compression reinforcement) where
on -going compressive stress exists and where
adequate shoring cannot be installed prior to
repairs to prevent displacements and corresponding
stress redistributions during repairs.

11.0 Summary
The repair of deteriorated concrete resulting from
reinforcing steel corrosion is necessary to extend
the service life of the structure. Performing
concrete repairs using industry -best practices will
ensure the success and longevity of the repair.
Understanding the existing conditions and cause
of corrosion will assist the engineer in specifying
the type and extent of the repair required, and the
type of corrosion mitigation systems and/or
preventative measures that should be considered
to protect the structure from future deterioration.
