  1. SealGuard II Polyurethane Grout Injection to Stop Water

    Comments Off on SealGuard II Polyurethane Grout Injection to Stop Water

    The seam on this dam tunnel was actively leaking water.  SealGuard II, a dual component polyurethane grout, was injected into the leak path to seal the water flow.  With just a drill, a dual component caulking gun, and some SealGuard II, a water leak of up to 50 gallons per minute can be stopped.  SealGuard II is manufactured by SealGuard, Inc. and the grouting was performed by Sub-Technical, Inc.
