1. Do not fill joints until existing joint removal operation has permanently ceased.

2. Do not fill joints until the expected air temperature is consistently above 40 degrees.

B. Remove dirt, debris, saw cuttings, curing compounds, and sealers from joints; leave contact faces of joint clean and dry. Blow out all dust and heat lance all to remove all moisture before sealing.

C. Install joint sealant in locations and as specified on the drawings. Do not overfill joint, maintain slightly below top of joint after hardening. Minimum joint depth shall be 1/2". For joints wider than 1/2" use a 1:1 ratio of depth to width.

3.2 CONCRETE SURFACE REPAIRS

A. Damaged Concrete: Repair and patch areas damaged during the removal of the existing sealant as specified by the Government.

B. Perform repairs of concrete, subject to COTR’s approval, using epoxy adhesive and patching mortar.

3.3 FIELD QUALITY CONTROL

A. Testing and Inspecting: Contractor shall perform a field pull test of the sealant to determine if the product is resulting in suitable adhesion of the material to the existing concrete surfaces. When the sealant is pulled it should tear instead of releasing from the concrete surface. If the product is determined not to be adhering to the surfaces, a different primer shall be recommended by the manufacturer and the test shall be performed again.

Testing area shall be no less than 8 feet.

B. Testing and Inspecting: Engage the manufacturer’s representative or testing agency to perform testing and inspections recommended by Sealant Manufacturer; or do pull test that is witnessed by COTR and Hatchery Manager.

3.4 PROTECTION OF JOINT SEALANTS

A. Protect joint sealants from damage and wear during the remainder of construction period and full curing time.
