PART 3 EXECUTION
A. Verify substrate conditions under provisions
of Section [ ].
A. Perform grouting to established concreting procedures
according to ACI recommendations. Clean all grout contact surfaces of
oil, grease, scale and other loose and deleterious substances. Chip
out unsound concrete, leaving surface level but rough.
B. Saturate grouting area with water 12-24 hours
prior to grouting. Remove all excess water before placing grout.
A. Observe application information and precautions
stated in manufacturer's literature.
B. Pouring: Forming must provide for rapid continuous
grout placement. For pouring, allow a minimum clearance of 3 inches
(76.2mm) for entry and 6 inches (152.4mm) minimum grout "head".
C. Venting: Forming must provide for venting to avoid air entrapment.
Do not make close fitting forms, allow 1/2 inch (12.7mm) clearance and
1 inch (25.4mm) for "head".
D. Mix, place and cure grout in accordance to manufacturer's written
