SPECIALTY EQUIPMENT:

A. Vacuum chuck and hollow drill bits.

B.     The equipment used to inject the epoxy shall be acceptable to the epoxy manufacturer and shall conform to all of the following:

1. Capacity to automatically proportion the epoxy material by was of positive displacement type pumps for each components. These pumps shall have the capacity of proportioning components within the tolerances set by the epoxy manufacturer.

2. Capacity to automatically mix the epoxy materials completely in line. Batch mixing will not be permitted.

3. Capacity to inject the epoxy resin under controlled, variable pressures.

4. Capacity to heat each component's reservoir container, and injection hose, so as to enable the heating of the resins to optimal injection temperature.

 

EXECUTION:

A. The top surface of the cracks designated for injection shall be cleaned free of dust, silt, laitance, oil and grease, or any other material that would interfere with the bond of the surface sealer.

B. Entry ports for epoxy shall be provided, spaced far enough apart to assure that when the adhesive material shows at the adjacent port, it has completely filled the crack to it's full depth. Entry ports shall be spaced along cracks and spacing usually determined by the tightness of the crack and the depth of the concrete substrate. Spacing is generally between 6 and 14 inches. A small reservoir shall be provided below the bottom of the port to aid in resin flow.

C. Injection ports shall be inserted into the drilled holes to about 1/2 inch allowing for the small reservoir below the port. The ports are then bordered into position with Epoxy Bonding Paste Product #5or #6, for wet or dry applications, or Epoxy.com Product #48 (Filler 7), for dry applications. Care will be taken not to seal the ports from resin flow. If surface port system is used, care will be taken to insure that the crack is open at the point below the port, and that there is a proper reservoir beneath the port.

D. A surface seal or epoxy patch meeting the requirements of this specification shall first be applied to the exterior crack to prevent the escape of the injection resin. The cracks shall be covered with a bead of Epoxy Bonding Paste Product #5, #6 or #48 and smoothed with a putty knife to insure sealing.

E. Injection of the epoxy resin into a crack shall, unless permitted by the Engineer, begin first at the entry port of lowest elevation and continue until uncontaminated epoxy flows out of the adjacent port. Injection pressure shall be kept as low as practical and shall generally be between 20 p.s.i and 30 p.s.i plus any hydrostatic head. The connection between the entry port and the mix head of the injection nozzle must be sufficiently tight to prevent epoxy from running out on the concrete surfaces.

F. After injection at a given port is complete, this port shall be plugged and injection started at the next adjacent port. This procedure shall be repeated until the crack is completely filled. Upon completion surface to be left as noted on the Drawings.

 

QUALITY CONTROL:

A. The overall quality of the work shall be judged by the Contractors ability to achieve 90% penetration of the cracks. In case of a question as to quality of work, the Engineer will have core samples taken from the completed work and assess the completeness of crack penetration.

B. The cores will be taken at location(s) determined by the Engineer and paid for by the OWNER. The contractor will not be responsible for the presence of inclusions of foreign matter in the cracks and susceptibility of such foreign matter to be removed by the recommended cleaning practices.

EXPERIENCE:

It is expected that the contractor will furnish adequate labor, material and equipment such that the work will progress with out any undue and unnecessary interruption.
