Why GreyCoat and HyperFlex?

GreyCoat is a premium 100% solids epoxy that offers outstanding chemical resistance and lasting durability with adhesion to concrete substrates and metal surfaces. Prepackaged as a no mess coating system that offers extensive coverage and shrink resistance, GreyCoat is excellent for structural spot repairs.

  • Structural repair
  • Long-lasting
  • Reduces product waste
  • Superior adhesion
  • Fast cure time
  • 100% solids monolithic

HyperFlex is a single component, pre-catalyzed hydrophobic polyurethane grout that has proven to be extremely versatile in a variety of infrastructure rehabilitation applications. Because of HyperFlex’s slower reaction time, the material is able to travel further with better coverage to seal the leak and protect against future infiltrations.

  • Pre-catalyzed
  • Water resistant
  • Extensive coverage
  • Non-shrinking
  • Long-lasting

Installation Steps:

Sealing a leak or crack in a basement can be a messy and time-consuming process. With S1E’s Basement Repair Kit, GreyCoat and HyperFlex work together in order to create a permanent and reliable repair. Ports are attached along the crack and secured in place using the GreyCoat two-part epoxy. GreyCoat is then applied throughout the crack. HyperFlex polyurethane is then injected into the ports—forcing the material deep inside the wall to create a seal.
