Professional Equipment and Materials to Stop Leaks
The largest kit for stopping leaking foundation cracks with Hydra Stop 300 polyurethane foam. Repair the leaking basement cracks from the inside of the basement. There is no digging, drilling holes or chiseling out the crack. Hydra Stop 300 Polyurethane foam is injected into your concrete cracks. After injection the Hydra Stop 300 begins to foam and expand. It seals cracks, voids and deteriorated concrete that leak water. Poxy Paste is a low odor mercaptan based fast setting surface port and crack seal adhesive. The Spring Drive Gun gives a smooth and continuous flow of the Hydra Stop 300 into the crack. This ensures that the crack is filled entirely the length of the crack. After curing the crack will not leak water.
