Now even homeowners can repair their own foundation leaks and save money. Make your basement dry by repairing the leaking foundation crack. Water will no longer be able to enter through the concrete crack. Your basement will be dry and have reduced mildew odors caused by a damp basement. We make it easy for the novice. No prior experience is needed. Just view the included instructional video.

Hydra Stop 300 is a low viscosity liquid. That means it will flow into cracks 1/32″ wide to seal them and stop water leaks. The urethane foams and expands inside the basement crack to expand and prevent water from entering your basement. Once the urethane has cured, it is tightly bonded to the concrete and cannot be pushed out by groundwater.

The Peel Paste Surface Sealer and Port Adhesive is removable. This gives the finished repair a clean look for when appearance matters.
