Professional Materials Stop Leaks-Easily Removed Surface Paste
The 60′ kit is the largest leak repair system that uses Hydra Stop 300 and Peel Paste removable surface sealer and port adhesive. When stopping concrete crack leaks and the appearance matters use the Peel Paste polyurethane foam kit. Hydra Stop 300 expanding polyurethane foam stops the water from leaking into the basement. Peel Paste surface port and crack seal adhesive is then simply peeled off the concrete surface. The plastic surface ports will come off too. 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.
