3.1 EPOXY MORTAR

A. Applicators Qualifications

1. Epoxy mortar repair work shall only be performed by contractors who have successfully used

this process on at least three similar structural repairs of equal scope which have performed

successfully for a minimum period of five years.

2. Only adequately trained and experienced personnel shall be used on the job.

B. Surface Preparation

1. Concrete surface to which the epoxy mortar is to be applied shall be exposed parent concrete

free of loose and unsound materials. Surface preparation shall be done by abrasive blasting,

waterblasting or as otherwise required by the manufacturer.

2. Necessary approvals shall be obtained by the Contractor from authorizing governmental or

other agencies prior to abrasive blasting. Abrasive blasting operations shall comply with the

requirements of OSHA and NIOSH (National Institute for Occupational Safety and Health)

Standard PB-246-697.

3. Surfaces shall be free of any deleterious materials such as laitance, dust, dirt, and oil.

4. Any exposed reinforcing steel shall also be cleaned and be free of rust and other

contaminants. Cleaning shall be accomplished by mechanical means. Use powered wire

brushes in locations where reinforcing steel cannot be cleaned by abrasive-blasting or water-

blasting. All exposed reinforcing steel shall be coated with a corrosion inhibiting product

specified elsewhere in this specification prior to mortar application.

5. Prime the cleaned surface with primer as required by the manufacturer.

C. Concrete Surface Inspection

1. Ensure that the surface temperature is at least 40°F to permit wetting of concrete surface by

epoxy coating.

2. The Contractor shall evaluate the moisture content of concrete surface receiving epoxy

mortar. This shall be done by determining if moisture will collect at bond lines between

concrete and epoxy mortar before epoxy has cured. Evaluate this by taping a piece of

polyethylene sheet to the concrete. If moisture collects on underside of the polyethylene sheet

before epoxy would cure, then allow concrete to dry sufficiently to prevent the possibility of

moisture between old concrete and new epoxy.

D. Mortar Application

1. Condition epoxy compound components to a temperature between 65°-80°F unless otherwise

recommended by the manufacturer. Epoxies beyond this range of temperature shall not be

used.

2. Stir each of the two parts of epoxy separately before mixing. Then mix in a clean container

free of contaminants.

3. Thoroughly blend epoxy components and sand with Jiffy mixers (made by The Jiffy Mixer

Co., Irvine, California) to a uniform and homogenous mixture. Small batches of one quart or

less may be mixed by spatulas, palette knives or similar devices.

4. Mixing should be accomplished well within the pot life of epoxy (three minutes when using




Jiffy mixer or five minutes when mixed by hand) after allowing for time required for

application.

5. Apply mortar by trowel or other means suitable for the consistency of the epoxy-sand mortar

mix.

6. Build up the repair area in layers with mortar thicknesses within those specified by the

manufacturer (1/4" maximum per layer).

7. Consolidate the mortar thoroughly to remove entrapped air.

8. Finish surface of mortar to match the texture and contours of existing concrete.

9. Allow mortar to cure in accordance to manufacturers recommendations.

E. Cleanup

1. Protect surfaces surrounding the work areas against spillage.

2. Epoxy and epoxy mortar spillages shall be cleaned before they set and become difficult to

remove.

3. Cleanup all portions of the existing structure that are soiled or stained in the process of epoxy

mortar repair work.

3.2 EPOXY GROUTED BOLTS, DOWELS OR REINFORCING STEEL

A. Applicator’s Qualifications

1. Epoxy grouting of bolts, dowels, or reinforcing steel shall only be performed by contractors

who have had successful experience on a minimum of three (3) projects of similar scope.

2. Only adequately trained epoxy applicators shall be used on the job. Furnish current certificate

of training on request.

B. Surface Preparation

1. All bolts, dowels and reinforcing bars shall be abrasive blasted no more than eight hours

before the grouting. If evidence of oxidation exists on the surface, the bolts, reinforcing bars

and dowels shall be recleaned. Blast-clean surfaces using Steel Structures Painting Council,

Surface Preparation No. 6, to give a surface condition corresponding to ASa2, BSa2, CSa2 of

SSPC Vis 1, depending on the initial surface condition of the steel surface. Prior to blast-

cleaning, clean surfaces to conform to SSPC SP1, SP2, and SP3, as required.

2. All holes shall be clean of dust, debris, and contaminants. Use compressed air from an oil-

and-water-free compressed air source prior to epoxy application.

C. Drilling Holes for Embedment

1. Use only rotary-percussion type drills for drilling holes.

2. Drills shall be fitted with bits having single tooth that produce large cuttings, and hollow stem

drill rods that permit simultaneous blowing of compressed air providing immediate expulsion

of the cuttings from the hole.

3. Do not cut through any reinforcing steel unless indicated otherwise on the drawings. Use

small diameter exploratory holes to detect presence of reinforcing steel prior to drilling holes

for grouting.

4. Core drilling equipment, and electric impact hammers or other tools which do not provide for

immediate expulsion of the drill cuttings shall not be used.




5. Unless noted otherwise on the drawings, depth of hole used for embedding the bolts, bars or

dowels shall be at least fifteen times their diameter.

6. Unless noted otherwise on the drawings, the center to center distance between the embedded

bolts, bars or dowels shall be at least twelve times their diameter.

7. Unless noted otherwise on the drawings, the edge distance shall be at least six times the

diameter of the bolt, bar or dowel.

8. Hole diameter shall normally be 1/4" larger than the outside diameter of the embedded item.

In no case shall the hole diameter be 3/8" larger than the diameter of the embedded item.

D. Epoxy Application

1. Condition epoxy compound materials at a temperature between 65°-80°F unless otherwise

recommended by the manufacturer. Epoxies beyond this range of temperature shall not be

used.

2. Mix epoxy materials in a clean container free of contaminants.

3. Thoroughly blend epoxy components with mechanical mixers to a uniform and homogenous

mixture. Mix small batches (up to 1 quart) by use of spatulas, palette knives, or similar

devices. Take care to use proper proportions of the epoxy components when using small

batches.

4. Mixing shall be accomplished well within the pot life of the epoxy after allowing for time

required for application.

5. Partially fill the hole with epoxy. Then insert the bolt, dowel or reinforcing bar into the hole

such that the resin material oozes out around the embedded item, ensuring complete contact.

Twist the bolt, dowel or bar slightly as it is inserted in the hole to ensure complete contact.

6. As an alternative to inserting the embedded item after the epoxy is poured in the hole, the

bolt, dowel, or bar may be positioned in the hole and filled up with epoxy by hand caulking

guns or injected with in-head mixing equipment. In either case, the nozzle shall be provided

with a hose or tube of sufficient length to reach the bottom of the hole being filled.

7. Where the holes are horizontal or overhead, the opening shall be covered by a masking or a

duct tape. Make a split in the tape and insert the epoxy injection tube through the split. Fill

hole completely with epoxy and then insert the embedded item through the split tape. Amount

of epoxy should be such that a small amount of material oozes through the split. Twist the

bolt, dowel or bar slightly as it is inserted in the hole to ensure complete contact.

8. Do not apply epoxy in the rain or in the presence of standing water.

E. Cleanup

1. Protect surfaces surrounding the work area against spillage.

2. Epoxy oozed out from the holes and spillages shall be cleaned before they become difficult to

remove.

3. Cleanup whatever portions of the existing structure are soiled or stained in the process of

grouting the bolts, dowels, or reinforcing bars.
