Resiplast Spetec GT 1100 Gel | Solvent and phthalate free, water reactive, hydrophilic, one-component flexible polyurethane injection resin designed to shut off water leaks.

Product Data Sheet


  • 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
  • Automatic sewer injections with packer systems
  • Soil stabilisation
  • Injection of water cut-off membranes and liners in tunnels


  • 1 Component hydrophilic PU resin, additional mechanical water shutoff through expansion after curing
  • Can be injected as 1 component or 2 component in combination with water
  • Depending on the amount of water added, a rubbery foam (200 to 500%) or stable PU gel (500 to 700%) is formed.
  • As 1C injection resin, PU GT1100 can be accelerated by adding maximum 5% H100 ACC or F400 ACC
  • 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.


Read the technical and safety data sheets prior to commencement of the injection works. Vigorously shake the H100 ACC or F400 ACC before use if used for the 1C application (max. 5%). Mix the accelerator homogeneously into the resin and protect against moisture and rain to prevent premature reaction.
