Fiberglass Reinforced Cured-in-Place Lining System

PerpetuWall™ is a cured-in-place composite liner system comprised of fiberglass cloth and a two-component, solvent-free 100% solids, ultra high build epoxy mastic designed to protect from corrosion and stop transmission of fluids also known as infiltration or exfiltration. PerpetuWall™ forms a monolithic liner that completely bonds and conforms to the host structure regardless of shape and size. The liner can be used as the primary protective barrier for structures or as part of a secondary containment system. PerpetuWall™ is designed for use with concrete and masonry structures, but can also be used on timber, metal, and plastic structures.

Typical Uses

New or existing structures where waterproofing is required, or areas where exposure to concentrated acids or other caustic materials may be expected, such as:

  • Manholes
  • Lift Stations
  • Clarifiers
  • Digesters
  • Tanks
  • Large Diameter Pipes
  • Chemical Troughs
  • Wastewater Facilities
  • Secondary Containment
  • Floors and Walls
  • Waterproofing for concrete, metal, and wood
