NextStar High Pressure Concrete Crack Repair Kit for poured concrete wall crack repairs. High-Pressure Polyurethane Foam Injection for crack repairs between 8-12' of small to hairline cracks that are actively leaking or not. Includes blended 100/800 viscosity Injection Foam, High-Pressure Gun, ½ inch packers, etc.

DESCRIPTION: High Pressure Crack Repair Kit provides HIGH PRESSURE injection repair of concrete foundation cracks as narrow as .002", and repairs 8-12' long of 8" thick poured foundation wall. Polyurethane material is injected up to 2500 psi with this repair method. The 100/800 Polyurethane expands on contact with water or moisture while sealing and expelling out water. This repair method works on actively leaking foundation cracks or all small concrete wall cracks. Ideal kit for those concrete wall cracks that have been previously repaired by hydraulic cement. The blended Polyurethane can expand to 25 times its volume size. For standard cracks with 1/6 inch or larger, we recommend using a low-pressure repair method instead.
