E. The expiration date of acceptance of this material shall be one year after the date of manufacture. Any unauthorized tampering or breaking of the seals on the containers between the time of sampling and delivery to the job site will be cause for rejection of the material.

3.1 GENERAL:

A. The locations for the pressure injection of cracks will be delineated by the Engineer.

B. Ensure that the epoxy manufacturer’s technical representative will be present for the duration of the injection process, and submit details of the proposed method of repairs and the injection procedure for approval.

C. Prior to beginning repair, clean all cracks of loose matter such as dirt, laitance, oil, grease, salt, or any other contaminants.

D. Inject the epoxy with a positive displacement pump system having a suitable mixing chamber where the epoxy components are accurately metered and thoroughly mixed immediately prior to injection. A clear, legible, and accurate pressure gauge shall be located in the supply line adjacent to the mixing chamber.

E. The equipment shall also be capable of providing a continuous and uninterrupted pressure head up to 200 psi to continually force the injection

PRESSURE INJECTED EPOXY CRACK REPAIR 03 64 23 - 3

T-1964-0150 ADDENDUM 2 SP-149C

of epoxy into the cracks. Epoxy flow shall be capable of being fully controlled by the operator controls at the mixing chamber.

F. Ensure that all working personnel are familiar with the equipment, materials, and procedures to be used during the operation.

G. All materials and equipment, including backup equipment, shall be at the work site before injection operations begin. All equipment shall be in proper calibration and in good working order as determined by the Engineer. A pressure check shall be performed by inserting two independent valves and gauges capable of sensing the pressure build-up behind each valve. The valves on the pressure check device shall be closed and the equipment operated until the gauge pressure on each line reads 200 psi. The pump shall be stopped, and the gauge pressure shall not drop below 190 psi within three minutes.

H. The pressure check shall be run for each injection machine at the beginning and at the end of every day that the unit is to be used in the work of crack repair.

I. Epoxy shall be injected only by the use of the automatic mechanical pumping, metering, and mixing equipment described above. Pressure pot systems and caulking guns or grease guns will not be permitted.

J. Mix the two components in accordance with the manufacturer’s recommendations. Maintain the ratio of the components within a tolerance of five percent by volume.

K. Acceptable solvents used for cleaning include mineral spirits, methyl ethyl ketone, acetone, low boiling naphtha, xylene, and any other nonchlorinated solvent.

3.2 PORT INSTALLATION:

A. Prior to injection of the epoxy in the crack, apply a surface seal material to the face of the crack to prevent the liquid resin from leaking out. The surface seal material shall be useable on vertical, horizontal, and overhead applications and completely bridge the crack when applied to the face of the crack.

B. Establish openings to inject the epoxy through the surface seal material along the entire length of the crack and provide entry ports. The holes shall be 3/4 in. diameter, spaced 6 to 12 in. apart and be of sufficient depth to ensure maximum dissemination of the pressure of the epoxy throughout this area.

C. Set inserts in drilled holes that are cleaned to remove any dust or debris left by drilling operations. Exercise special care to ensure that oil or other contaminants are not introduced into the air feed hoses, or deposited on any air blown surfaces.

PRESSURE INJECTED EPOXY CRACK REPAIR 03 64 23 - 4

T-1964-0150 ADDENDUM 2 SP-149D

3.3 INJECTION:

A. Force the epoxy into the internal voids and cracks by means of hydraulic pressure to completely fill all internal voids. If the surface seal material has insufficient strength and adhesion to confine the injected epoxy until it has cured, remove the surface seal material and furnish and place a new surface seal material at no additional cost to MTA.

B. Before injecting any epoxy, test for proper epoxy component mix ratio by removing the mixing head of the injection machine and simultaneously pumping approximately 1 total pint of the two adhesive components through the ratio check device. Both adhesive components shall be simultaneously discharged into the calibrated containers during the same time period and shall be compared to determine the mix ratio. Test the mixing head by activate the automatic mixing and metering pump and discharge approximately 1 pint of the mixed epoxy into a disposable container. The Engineer will observe this trial operation to determine that the equipment is working properly. If the equipment is not working properly, immediately repair it to full working condition or replace with the backup equipment. If the backup equipment is used, additional and fully operable equipment shall be provided as its backup equipment.

C. Testing for proper epoxy component mix ratio shall be performed at the beginning and at the end of every day the unit is used in the work of crack repair.

D. At all times during the course of the work, the contractor must keep complete and accurate records available to the engineer of the ratio and pressure tests.

E. The engineer at any time without prior notification of the Contractor may request the contractor to conduct additional ratio and pressure tests. This request may be made up to one time per day per test.

F. Ensure that the feed line from the mixing equipment is securely held or properly attached to the port. Then initiate the epoxy injection in conformance with the manufacturer’s recommendations.

G. Start the injection at the lowest row of holes and at the hole nearest the center line of structure. Continue injection at the first port until the epoxy begins to flow out of the port at the next highest elevation. Then plug the first port and start injection at the second port until the epoxy flows from the next port. Continue this sequence until the entire crack is repaired.

H. Monitor the injection procedure to ensure the epoxy flow does not cease before the injection epoxy exudes from the adjacent port. If the epoxy flow stops before epoxy appears at the adjacent port, move the feed line to the adjacent port and seal the port just used.

I. During the course of all operations, ensure extreme care to observe for breaking out of epoxy. When breaking out occurs, stop the injection and

PRESSURE INJECTED EPOXY CRACK REPAIR 03 64 23 - 5

T-1964-0150 ADDENDUM 2 SP-149E

move the line to another crack. Resume injecting in the original location after a minimum elapse of 24 hours.

J. Accomplish a continuous injection operation by replenishing the epoxy supply tanks in the mixing equipment before they are exhausted.

Thoroughly stir each epoxy component before adding it to its respective storage tank in the mixing equipment. No discontinuity of epoxy flow through the feed lines of either component shall be permitted.

K. The Contractor shall provide the Resident Engineer with dispensed samples, not exceeding 2 fluid ounces, whenever requested. The samples are to be taken undisturbed at the outlet following in-line mixing. These samples are to be provided in addition to any sampling or other procedures recommended by the manufacturer of the proportioning dispenser.

L. Any work stoppage permitting mixed epoxy to remain in the injection equipment more than 15 minutes requires cleaning the mixing chamber and all equipment in contact with the mixed epoxy. Quantities of epoxy purged from the injection equipment shall not be included for payment.

M. After the injection process has been completed and the epoxy allowed to fully cure, remove the injection ports and surface seal from all surfaces. Cut or knock off ports, and grind off the surface seal and any spillage flush with the original surface.

N. Repair any damage to the concrete due to these operations in a manner satisfactory to the Engineer at no additional cost to MTA.

O. The cured injected epoxy shall have penetrated a minimum of 90 percent of the visible crack. Acceptance will be based upon drilling cores of the repaired concrete to determine the depth of penetration from representative locations selected by the Engineer. If the penetration is less than 90 percent of the visible crack along the sides of the core, the crack from which the core was taken will be deemed unsatisfactory and will not be included for payment. A minimum of three 4 in. diameter core samples for the full crack depth of the member or area being repaired shall be required for each 100 ft or fraction thereof per job site. Fill the cored holes with epoxy grout.

3.4 CORE TESTING:

A. Core testing requirements for this project shall be determined by the Resident Engineer based on the conditins encountered on site at the time of the repairs.

B. When required, cores shall be removed periodically at the sole discretion of Resident Engineer. The results evident by core examination shall be the sole criteria in determining whether the requirements of the specification have been met. The cores shall be at least 2” diameter and 6” in depth. Core locations shall be selected by the Resident Engineer and shall be removed only in the presence of the MTA representative. Cores and core holes shall be carefully indexed as to location.

PRESSURE INJECTED EPOXY CRACK REPAIR 03 64 23 - 6

T-1964-0150 ADDENDUM 2 SP-149F

C. Injection cannot proceed beyond the initial 50 feet until two cores have been submitted to, and approved by, the Resident Engineer.

D. One core is to be furnished from each additional 100 feet or as requested by the Resident Engineer. No cores will be required within 3” of the extremity of the crack seal.

E. Following their removal, the cores will be examined for penetration. If requirements are met, the cores will be demolished. If no major fracture occurs on a glue line, the core is acceptable. If the core breaks on a glue line, the fragments shall be inspected and/or tested to determine if the failure is attributable to improper metering or mixing of the epoxy. If so, the core shall be considered unsatisfactory and additional cores will be required of the contractor at his own expense from the same vicinity to determine the scope of defective work.

F. All cores shall be filled after inspection with rapid hardening cementitious material at no additional cost to MTA.

4.1 PRESSURE INJECTED EPOXY CRACK REPAIR:

A. Pressure Injected Epoxy Crack Repair will not be measured for payment.

B. Pressure Injected Epoxy Crack Repair will not be paid for directly, but will be included in the Reinforced Concrete Bus Pad And Monolithic Curb Repair Item.
