1. Remove unsound and foreign materials from the crack in a manner that does not trap debris in the crack and prevent the flow of repair materials.

2. Remove contamination by flushing with water or solvent, allowing adequate time for air-drying or blow out the solvent with compressed air. Any solvents must be fully flushed from the joint unless NSF/ANSI Standard 61 approved.

3. Install the injection ports in accordance with the manufacturer’s directions.

NRCS Spec 35-5

4. Moisture

• For non-structural cracks, moisture must be present for the chemical grout to react.

• Prior to injecting the repair materials, inject the crack with a small amount of water in order to completely moisten the crack.

5. Inject the repair materials, with consideration of the following items:

• Carefully select the pressure of the hydraulic pump or other device, because too much pressure can extend the existing cracks and cause more damage.

• For vertical cracks, start by pumping material into the entry port at the lowest elevation until the material level reaches the entry port above, cap the lower injection port and repeat the process at successively higher ports until the crack has been completely filled, and then, starting again at the lowest port, re-inject into all ports in order to ensure that all voids are properly sealed off.

• For horizontal cracks, start at one end of the crack and work to the other end, filling the crack until the pressure can be maintained.

• For very fine cracks, start the injection of repair material at the widest end and proceed toward the thinner end.

6. Cleanup

• Remove excess surface material by grinding or other appropriate means.

• Coat fittings and holes at injection ports with an epoxy patching compound.

• If crack repairs are part of repair for surface defects, painting with epoxy is not necessary and surface preparation may be started after crack repairs have been completed.

3.6 GROUT FOR LOW-LEVEL GATE REPLACEMENT

A. For low-level gate frame, the Contractor shall clean and prepare the surface as described in Article 3.2. Then the Contractor shall place bonding agent prior to placing grout seal material in compliance with manufacturer’s recommendations and in accordance with the Drawings and General Notes.

3.7 DISPOSAL

A. The Contractor shall dispose of all concrete and debris from the repair works offsite and per applicable permits by the Contractor.

B. No material may be disposed of by burial or burning onsite.

3.8 DUST CONTROL

A. The stabilization measures contained in this section are for controlling air movement of

NRCS Spec 35-6 dust on construction sites.

B. Dust may be controlled by use of irrigation. Irrigation may be accomplished by sprinkling water on the surface until the surface is wet and no longer produces dust or by applying a constant stream of water (i.e. - wet saw). This must be repeated as necessary to minimize dust production.
