Background:
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.
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. 03 73 0)
• 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):

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.

GUIDE FOR SURFACE PREPARATION FOR THE REPAIR OF DETERIORATED CONCRETE RESULTING FROM REIN.FORCING STEEL CORROSION 310.1R-2008
1.0 Introducthe! . n-
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 ofthe
removal cavity to provide a clean sound surface
to bond a repair material.
.This guideline outlines removal geometry,
configuriffion,, 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 otherremoval
techniques. Special caution should be taken to
locate and avoid cuffing or damaging embedded
reinforcing bars, prestressing strands, post -
tensioning tendons, or electrical conduits. Cutting
into these items can be life threatening and may
signifiriantly 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 mu the givento 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 wiH.vary due to
many different factors. Each project should be
evaluated individuallyto aiscertaintheapplic�bility-
of the procedures described herein. Refer to ACI
506R-05, "Guideto Shoterete"for surface prepar-
ation prior to shotcrete application.

(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.

repair cavity is achieved by providing a -uniform
chemical environment around the reinforcing
steel. If noncorroded 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 not used, the repair may be compromised
due to continued corrosion. If there is a potential
trade-off between durability and structural
capacity, structuralcapacity 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-contarninated 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 steelis susceptible to corrosion as a
result of.carbonation, a corrosion inhibiting
system should be considered to minimize future
corrosion. Othermeasures 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.

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 sp ecial
condition and is discussed in Section 10.

Concretc�. 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 Pierimeter
ne perimeter of the repair area should be saw
cut 0.75 in. (19 min) deep to provide a vertical
edge (Fig. 7.2) for the repair material. This will
avoid featheredging of the repair material.
Depending on tii6 ; repair material selected, the
depth of.the existing reinforcing and the
manufacturer's recommendations, a saw cut depth
less than 0.75 in.* (19 min) deep may be sufficient.
Carc sluml d be taken to avoid cutting the existing
reinforcing siteel..
7.3 Clelarving of the
Cohdrete.,-Surface and

The use of high-finpact, mechanical methods to
remove deteriorated concrete will result in a
surface layer weakened by interconnected micro -
cracks 'in the concrete'substrate. The fractured

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 lightrustbuild-up onthe 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
Reinf orcing, 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
I N S T 1 7 U T E
darriagod/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 supplcmental reinforcing
steel should extend (lap length) beyond the
damaged/deteriorated area in accordance with
ACI 318, "Building Code Requirements for
Structural Concrete."
9,0 Finial Surface
Inspiection
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 withthe 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
ASI-M 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 efigineer:and included as a performance
specification fortre repair.'

Undercutting of reinforcement is a best P . ra -�tlde
in tensile zones of concrete. In columns, the
primary loading condition is compression. From
a design perspective, the concrete section
containedwithinthe reinforcing cage is considered
to carry the compressive loads (Fig. 10.1). The
concrete outside ofthe reinforcementis 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 CFig. 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 str6ss
state. The new material will not carry compressive
loads until the original concrete compresses further,
forcing the repair material into compression' if
farther compression is beyond the capacity ofthe
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 thereinforcement
cage, a qualified structural engineer should
determine the impact of the repair on potential
reinforcement buckling and overall itnictural
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 preventdisplacements andcorresponaing
stress redistributions during repairs. , �! %

-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 specitling
the typ e and extent ofthe repair required, and the
type of corrosion mitigation systems and/or

How to Use
Substrate Concrete, mortar, and masonry products.
Surface Preparation Concrete: Remove all deteriorated concrete, dirt, oil, grease, andall bond -inhibiting materials
from surface. Be sure repair area is not less than 1 in. in depth. Preparation work should be
done by high pressu ' re water blast, scabbler, or other appropriate mechanical means to obtain
an 0xposd&aggfagat6surf6c.d with a minimum surface profile of ±1/8 in. (CSP-7). Saturate
surface with.clean water. Substrate should be saturated surface dry (SSD) with no standing
water during applicaltion.
Rainforcing:Steel: Steel reinforcement should be thoroughly prepared by mechanical cleaning
toremove 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
rainfaffina.steel use Sikao Armatecn 110 EooCem (consult Technical Data Sheet).
Mixing Place 4/5 of 1 gallon water in mixing container. Add Sikacret& 211 while continuing to mix.
0
Add additional water up to 1 gallon total. Mix to a uniform c nsistency, maximum 3 minutes.
N Mechanically mix with a low -speed drill (400-600 rpm) and paddle or in appropriate size mortar
mixer of concrete mixer.
Application Form andro.our or pump applications: Pre-wetsurface to SSD. Ensure good intimate con-
tact with the substrate is achieved. To accomplish this, material should be scrubbed into the
substrate or other suitable means should be employed such as vibration of the material or
p6mping,under pressure. Vibrate form while pouring or pumping. Pump with a variable pres-
surd pump. Continue pumping until a 3 to 5 psi increase in no.rmal line pressure is evident
then'STOP pumping. Form should not deflect Vent to be capped when steady flow is evident,
and forms -stripped when appropriate.
Tooling &finishing As per ACI recommendations for portland cement concrete, curing is required. Moist cure
with wet burlap and polyethylene, a fine mist of water or a water based* compatible curing
compound. Curing compounds adversely affect the adhesion of following layers of mortar,
leveling mortar or protective coatings. Moist curing should commerce, immediately after fin-
ishing. Protect newly applied material from direct sunlight, wind, rain and frost.
Limitations m Application thickness: Minimum 1 in. (25 mm); Maximum 8 in. (200 mm)
In Minimum ambient and surface temperatures 45'F-(7'C) and rising at time of application.
u Using Sikal-atexa, Sikal-atee R or similar products will result in loss of slump and slump
retention. �ield tests for suitability are strongly recommended.

Description
Me FerroGard 903 Is a corrosion Inhibiting Impregnation coating for hardened concrete surfaces. It Is
a a nforcing bars
designed to penetrate the surface and then to diffuse In vapor or liquid form to the te I rel
embedded in the concrete. Sika FerroGard 903forms a protective layer on the steel surface which Inhibits
corrosion caused by the presence of chlorides as well as by carbonation of concrete.
Sika FemoGard 903 is a combination of arnino alcohols, and organic and inorganic inhibitors that protects
both the anodic and cathodic parts of the corrosion cell. This dual action effect dramatically delays the InItla-
tion of corrosion and greatly reduces the overall corrosion activity.
FerroGard 903 protects the embedded steel by depositing a physical barrier in the form of a protective
on the surface of the steel reinforcement. This b6rfier inhibits corrosion of the steel.

• Steel-rehlorced concrete, bddges and highways exposed to co=ive environments ideicing salts, weathering)
• Building facades and balconies
• Steel -reinforced concrete In or near a marine environment
• Parking garages
• Piers, plies, and concrete dock structures
• As Dart ofSikWs system approach for buildings and Civil engineering structures
Advantages S[ka FerroGard,903 offers owners, specifiers, port authorities, DOTS, and engineers. a new technology In
corroslon inhibition that can easily be applied to the surface, of existing concrete to extend the service life of
any reinforced concrete structure.

• Meets the standards of acceptability forconcrete sealers established in NCHRP Report#244.
• Enhances concrete integrity.
• Reduces efflorescence.
• Improves resistance to frost and deicing salts (chloride ion).
• Reduces dirt penetration.
• Does not act as a vapor barrier.
• May be applied to alkaline substrates.
Will not degrade under UV exposure.
Coverage 100-250 sq. ft./gal., (diluted concentrate) depending on porosity of substrate. For proven
results against chloride-lon intrusion, 125 sq. ft./gal. is recommended.

How to Use
surface Preparation
Before applying Sikagard 701W. be sure surface is clean and sound. The best impregna-
tion Is achieved an a dry, very absorbent substrate. Remove all grease, curing compounds,
surface treatments, coating, oils, etc.
Preparation Work: Concrete and masonry surfaces, sandblast, high pressure water blast or
use other mechanical means.
Mixing
Dilute Sikagard 701W concentrate with tap water in an appropriately sized mixing container

uniformly blended. Make sure paddle is completely covered so as not to entrain air. For best
results, Sikagard 701W should be remixed if unused 24 hours after blending with water.
Application
Apply by roller, orush (horizontal surfaces), or spray. Any pooling of water repellent indicates
rapid absorption indicates a porous substrate. Varia-
overdosing an a dense substrate while
tlon� in concentration down to 8:1 for dense substrates or coverage area, and/or multiple
wet -on -wet applications for porous substrates,may be utilized to achieve optimal substrate
treatment. Preliminary site test application is recommended to determine effective coverage
and performance. maximum watenrep gilency Is generally realized in 72 hours, but may
take longer depending on surface -and atmospheric conditions.
Limitations
x Adjacent surfaces such.as window frames, glass, stainless steel, aluminum, etc., must be
masked -before application.
m Do not apply at a temperature below 40*F.
