Applications

  • Shut off water leaks in concrete, brickwork and sewers where movement and settlement may occur.
  • Water cut-off of water leaks in foundations such as diaphragm walls, piling sheets and secant piles.
  • Sealing water-carrying cracks and joints in tunnel segments.
  • Curtain grouting behind tunnel, concrete, brickwork and sewer walls.
  • Injection of failing membranes and liners in tunnels and buildings.

Advantages

  • One component hydrophilic PUR resin, additional waterproofing due to post-expansion.
  • Fast reaction with an immediate increase of viscosity.
  • Can be injected as 1 component or 2 component in combination with water, maximum amount of water = 200%.
  • Foam factor 6-8x.
  • Cured polyurethane is highly flexible, ideally suited for structures where a high degree of settlement and movement can occur.
  • Cured polyurethane is harmless for the environment and resistant to biological attacks.
