OBIC 2261 & OBIC 2262 MaxSeal

Typical Use

OBIC 2261 & OBIC 2262 MaxSeal is a dual-component moisture activated, expanding, rigid hydrophobic polyurethane foam. OBIC 2061 & OBIC 2062 MaxSeal is designed to permeate soil granules and fill large and small voids where water is leaking into structures. It withstands wet/dry cycles, permeates well, and reacts quickly with water to form a dense, impermeable rigid foam. The convenient cartridge package allows easy access to hard-to-reach places.

  • Fills voids on the exterior of below-grade structures
  • Stops mid to high volume and mid to high pressure leaks in below-grade structures
