This limestone quarry was experiencing large volumes of ground water which was flooding the pit. To reduce the need for costly pumping, the high wall was injected with polyurethane grout. The grout used was SealGuard II. SealGuard II is a dual component polyurethane that reacts within seconds to form a 900 PSI compression strength foam. SealGuard II is produced by SealGuard, Inc. and the grouting was performed by Sub-Technical, Inc.
