B. Cracked substrates with cracks wider than 0.01 inch must be pressure injected with epoxy

prior to FRP installation.

C. Existing concave and convex surfaces (including mortar joints) must be filled/transitioned with epoxy paste or a suitable repair mortar. To repair voids, CSS-EP or CSS-ES thickened with fumed silica may be extended with FX-702 at no more than a 1:1 ratio by volume.

3.02 SURFACE MOUNTED APPLICATION

A. Verify ambient and masonry surface temperatures are between 45°F and 95°F.

B. Apply two coats of epoxy primer using a nap roller, allowing the first coat to soak in for several minutes when using fabrics.

C. Apply epoxy paste where minor surface defects are present, to fill in masonry joints and

apply a thin layer where all FRP will be installed.

D. Allow the primer and/or paste to become tacky to the touch before applying the saturated fabric.

E. When manually saturating fabric, precut sheets to required length using heavy duty shears

before saturating with hand rollers. If mechanically saturating fabric with rollers, cut sheets using heavy duty shears either before or after they go through the epoxy bath. In both cases, ensure full fabric saturation is achieved.

F. Apply the saturated fabric to the installation surface and remove entrapped air using hand

pressure, rollers, or trowels.

G. Apply additional layers as necessary to meet the project requirements, ensuring each layer is firmly adhered to the previous layer.

H. Feather all fabric seams/edges with epoxy paste.

I. Confirm that intimate contact between composite system and substrate will be maintained

throughout the curing process.

J. Apply finish coating after full epoxy cure, lightly sanding epoxy surfaces before installation. 3.03 QUALITY CONTROL

A. Field Monitoring 1. The work performed in the preceding sections of Part 3 of this specification will be

field monitored by the Owner’s Special Inspection Agency and will be paid for by the owner. The surface preparation shall be checked immediately before application of the composite system materials. Periodic inspection shall be provided during the application process.




2. The special inspector shall create daily reports that document the following: a. Date and time of installation. b. Ambient temperature, relative humidity, and weather conditions. c. Substrate surface temperature and dryness. d. Surface preparation method. e. Surface cleanliness description. f. Fabric batch numbers. g. Epoxy batch numbers, mix ratios, and mixing times. h. Application locations. i. Conformance with installation procedures. j. Location and size of any delaminations/voids identified or repaired.

3. For fabric systems, the contractor shall create a minimum of two material sample sets daily. Each set will consist of two 12 in. by 12 in. panels made of two layers of saturated fabric and the sets shall be taken at different times during the working shift so that it is representative of maximum variances in material/site conditions. Prepare samples on a flat, level surface covered with heavy-duty vinyl (or similar). Prime vinyl with epoxy saturant, place saturated layers, and apply a top coat of epoxy saturant. Samples shall be cured at the site under the same environmental conditions as the production work they represent and must be marked with sample date, time, epoxy/fabric batch numbers, and installation locations.

B. Field Testing

1. Adhesion Tests a. Pull-off tests shall be conducted in accordance with ASTM D7522 and/or

ASTM D4541 and performed on flat surfaces. 3 tests shall be executed on each type of substrate or surface preparation method used, with a minimum of 3 tests per 1000 square feet of surface area covered. Testing shall be done on an area adjacent to strengthening locations with substrate, surface preparation, and orientation (i.e. overhead, vertical, etc.) that are representative of that being strengthened. Before pull-off tests are performed, the composite system shall be allowed to reach full cure.

b. Adhesion tests shall exhibit failure in the masonry substrate.

C. Lab Testing 1. Tension Tests

a. General 1) Lab tension tests are only required when structural performance criteria

is specified. 2) Tension tests shall be performed to verify the tensile strength, strain, and

modulus of the composite strengthening system based on the nominal layer thickness reported on the manufacturer’s data sheet and used in the design calculations.

3) The composite tensile properties used in the design calculations must be lower than the average of the test results unless calculations are performed with the reported average tensile properties show that the strengthening requirements are satisfied.

b. Fabric Systems 1) One panel from a minimum of 15% of all sample sets shall be selected

for tension testing performed in accordance with ASTM D7565 and/or ASTM D3039.

D. Defects

1. Small delaminations less than 2 square inches are acceptable so long as the delaminated area is less than 5% of the total laminate area and there are no more than 10 such delaminations per 10 square feet.




2. Large delaminations greater than 25 square inches shall be locally cut away and a new material shall be applied with an equivalent number of layers and sufficient development length overlaps.

3. Delaminations between 2 square inches and 25 square inches shall be injected with epoxy or replaced, depending on the size, number of delaminations, and locations.

E. Remedial Measures

1. If the composite tensile properties used in the design calculations are higher than the average of the laboratory test results, design calculations shall be resubmitted, showing that the target design performance has been achieved. If this is not the case, additional layers shall be applied until the target design performance is reached.
