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.

The picture on the left is water traveling down the outside of de-watering pipe in a hard rock mine. The picture on the right is after the annulus of the pipe was injected with polyurethane grout to control the unwanted groundwater infiltration. This high-pressure injection of grout was able to stop the water in about fifteen minutes. The polyurethane grout used was SealGuard II, dual component material that reacts in 1-3 seconds to create a rigid foam. SealGuard II is manufactured by SealGuard, Inc. and the injection was performed by Sub-Technical, Inc.
