InfraRentals Expanding Seal

When maximum tightness is required for sheet piling, especially in landfill construction with contaminated soil, a polyurethane (PU) based interlock seal provides the solution in many cases. InfraRentals Expanding Seal is a product that leads to a watertight wall. The water-swellable polyurethane (PU) based sealant swells on contact with moisture up to 350% of its original dry state. It is applied to the sheet pile wall interlocks prior to site with a simple putty gun to seal them.

 

InfraRentals Expanding Seal has been specifically designed for the following applications

  • Sealing of interlocks between sheet piles.
  • Sealing of construction joints in cast-in-place concrete in a damp substrate.
  • Sealing of joints in prefabricated concrete elements (shafts, cable or pipe penetrations in wet or underwater conditions).
