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):
• Sikacrete 211 Concrete Mix.
• SikaTop 123 PLUS.
• Sika Armatec 110 EpoCem bonding agent and rebar coating.
• Sika FerroGard 903.
• Sikagard 701W.
• Neogard Decorative Peda-Gard
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.

About ICRI Guidelines
The Jnternational Concrete Repairlitstitute (7CRV
wasfounded to improve the durability of concrete
repair andenhance its vahteforstructure owners.
The identification, development, andpromotion of
the most promising methods and materials are
prima?y vehicles for accelerating advances in
repair technology. Working through a variety of
forums, JCR1 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
reported in the literature on concrete repair
methods andinaterials as theyherve been developed
and refined Nevertheless, it has been difficult to
find critically reviewedinformation on the state of
the art condensed into easy-to-useformats.
To that end, ICRI guidelines are prepared by
sanctioned tosk groups and approved by the 1CRI
TechnicalActivides Committee. Each guideline is
designed to address a specific area of practice
recognized as essential to the achievement of
durable repairs. A111CRIguideline documents are
subject to continualreview by the membership and
may be revised as approved by the Technical
Activities Committee.

GUIDE FOR SURFACE PREPARATION FOR THE REPAIR OF DETERIORATED CONCRETE RESULTING FROM REINFORCING STEEL CORROSION 31OAR-2008
ibis 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,
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 priorto 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 ha-;e
been used to successfully remove concreteand.
prepare the removal cavity on many prcjects� the
requirements for each project will vary due to
many different factors. Each project should be
evaluated individuallyto ascertaintherapplicability-
of the procedures described herein. Refer to ACE
506R-05, "Guide to Shotcrete" for surface prepar-
ation prior to shotcrete application.
Anodic ring egect: Corrosionprocessinwhich
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).

typicaIl� 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 corrosi . on.
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.
I 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.
AUcrocrack: Acracktoo 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
resi sting under axial tensile loading and the near -
surface tensile strength of a prepared surface
(refer to- ICRI Technical Guideline No. 210.3-
2004 [formerly N�.. 03739] and ASTM C1583).

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 not used, the repair may 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 cor�Tosion inhib-
iting systems should be considered. These
systems may include use of corrosion inhibitors,
sacrificial anodes, or cathodic protection.
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 ch'16TIde-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 steclis 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. Li 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-te�rrn repair.
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 onhorizontal, vertical, and/oroverhead
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.yeinforcing or to expose the
reinforcing (conebet e in compression) is a special
condition and is i n Section 10.

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 6 in. (152 mm)
beyondthe 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
rectangularwith square comers (Fig. 6.1). This may
result in the removal ofsound concrete. Reentrant
comers should be minimized or avoided, as they
are susceptible to cracking.

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

protective coating is applied to the reinforcing
steel, follow the coating manufacturer's recom-
mendations for. steel surface preparation.

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

(Fig. 8.1). Supplemental reinforcing steel maybe
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."
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 of the repair material to the
existing concrete) have been removed. If bond -
inhibiting materials are prcsent� 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
pulloff strength requirement should be established
by the engineer. and included as a perforniance
specification'. . for.the, repair.

Undercutting of reinforcement is a best practilde
in tensile zones of concrete. In columns, the
primary loading condition is compression. From
a design perspective, the concrete section
containedvvithiiathereinforcingcageis considered
to carry the compressive loads (Fig. 10.1). The
concrete outside ofthereinforcemen . tis considered
as protective concrete coverforfire 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 farther,
forcing the repair material into compression. If
further compression is beyond the capacity ofthe
existing concrete, failure of the column may
occur. This key concept affects theconcrete
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 provi de for a long-teraidurable repair.
To remove concrete around vertical reinforcing
steel in a column (removing concrete inside the
reinforcing bar cage) can cause the rernaining
concrete and/or reinforcement in the column to
become overstressed. From a structura I point of
view, this condition may not be desirable. If
concrete is to beremoved inside thereirribreement
cage, a qualified structural engineer should
determine the impact. of the repair on.po.f6ntial
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 pr, iiOr to
repairs to prevent displacerrentsand corresponding
stress redistributions during repairs. : - 1 .

The repair ofdeteriorated concrete resulting from
reinforcing steel corrosion is necessary to extend
the service life of the structure. Performing
concrete repairs using industry-bestpractices 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.

surface Preparation Concrete: Removeall deteriorated concrete, dirt, oil, grease, andall bond -inhibiting materials
from surface. -Be sure repair area is not less than I in. in depth. Preparation work should be
doneby high pressure water blast, scabbler, or other appropriate mechanical means to obtain
an q,xpo46d;9§gfegat&surfdcd with a minimum surface.proffle of ±1/8 in. (CSP-7). Saturate
surface with.clean water. Substrate should bes.atu.rated surface dry (SSD) with no standing
water during application.
Reinf6rcing: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
mininnrina-steel use Sikao'Armateco 110 EooCem (consult Technical Data Sheet).
Priming
Forprim, ihg,.of reinforcing steel use Sikas'Armatee 110 EpoGenn (consult lecrinicai Liata bneet).
Mixing
Place 415 of I gallon water in mixing container. Add SikacreteO 211 while continuing to mix.
Add additional water up to I gallon total. Mix to a uniform conslstenc�4 maximum 3 minutes.
Mechanically mixwith a low -speed drill (400-600 rpm) and paddle orin appropriate size mortar
mixer of concrete mixer.
Application
Forrn.and�.Pour or pump applications: Pre -wet surface to SSD. Ensure good intimate con-
tactwiththe substrate is achieved. To accomplish this, material should be scrubbed into the
ril
substrate or other suitable means should be employed such as vibration of the mate at or
pumping under pressure. Vibrate form while pouring or pumping. Pump with a variable pres-
sure pump. Continue pumping until a 3 to 5 psi increase in normal line pressure is evident
then STOP pumping. Form should not deflect. Veritto be capped when steady flow is evident,
and form s stripped when appropriate.
Tooling & finishing
As per ACIrecommenclations 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 commence immediately after fin-
ishing. Protect newly applied material from direct sunlight, wind, rain and frost.
*Preteatling of curing compound is recommended.

Sika FerroGard 003
Slika Ferro Galr& 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. Slka FemoGard 903forms a protective layer on the steel surface which Inhibits
corrosion caused by the presence of chlorides as well as by carbonation of concrete. I
How It Works
Bike FemoGard 903 is a combination of amino alcohols, and organic and Inorganic inhibitors that protects
both the anodic and cathodic parts of the corrosion cell. This due] action effect dramatically delays the Inifla-
Vion of corrosion and greatly reduces the overall corrosion activity.
Slka FermGard 903 proteots the embedded steel by depositing a physical barrier in the form of a protective
layer on We surface of the steel reinfoicemeriL This barrier Inhibits corrosion of the steel.
Where to use
SIM FerroGard 903 is recommended for all steel -reinforced, prestressed, precast, post tensioned or marine
�oncrete. Use of Sika FerroGard 903:
• SteeWiMblead concrete, bridges and tilghways exposed to cormsive environments (deicing salts, Weathering)
• Builifingfacades and balconies
• Steel-reiriforced concrete In or near a marine environment
• Parking1garages;
• * Piers, piles, and concrete dock structures
• As part ofSika's system approach for buildings and civil engineering structures
Advantages

z Enhancesthe durability of reinforced concrete.
z Does not require concrete removal.
x Environmentally sound.
x Does not contain calcium nitrite.
.1111 Easily applied by either�spray or roller to all -existing reinforced concrete.
m Can be applied to reinforced concrete that already exhibits corrosion.
x Adds additional benefits when used prior to protective coatings In concrete restoration systems.
.2 Water based for easy handling and application.
z Not a vapor barrier, allows vapor diffusion.
z FemoGardihas been proven effective in both laboratory (ASTM G1 091Cracked Beams) and field analysis.
w ANSIINSF Standard 61 potable water approved
Coverage
For normal concrete, application Is 200 ft.2/gal. each coat. A minimum of two coats is always recommended.

How to Use
Surface Preparation Before applying Sikbgard 701W, be sure surface is clean and sound. The best impregna-
tion is achieved on 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 appropidately sized mixing container.
Mix with a low speed (400-600 rpm) drill with Sika paddle or comparable drum mixer until
uniformly blended. Make sure paddle is completely covered so as not to entrain air. For best
results, Slikagard 701W should be remixed if unused 24 hours after blending With water.
Application Apply by roller, brush (horizontal surfaces), or spray. Any pooling of water repellent indicates
overdosing on a dense substrate while rapid absorption indicates a porous substrate. Varia-
tlon� in concentration down to 8:1 for dense substrates or coverage area, and/or multiple
wet -on -wet applications for porous substratosmay be utilized to achieve optimal substrate
treatment. Preliminary site test appliesition is recommended to determine effective coverage
and performance. Maximum waterrapellency is generally realized in 72 hours, but may
take longer depending on surface -and atmospheric conditions.
Limitations in Adjacent surfaces such. as window berries, glass, stainless steel, aluminum, etc., must be
maskedr before application.
. Do notapply at a temperature below 40T.
a Do not apply when substrate temperature exceeds 120T.
a Material is not recommended for belowwgrade waterproofing.
w Do notapply through standing water.
m Material is not Intended to seal visiblis cracks or crevices from moisture intrusion.
z Material is not intended for waterpmofing under hydrostatic pressure.
W Perform anGe and penetration depth are dependent upo I n the surface composition.
is Do trot use on green concrete.
• Whemovercoating: an on -site adhesion test is essential to determine actual compatibility.
• Sikagard 701W is not a carbonation barrier.
