Polyurethane flexible injection resin for temporary waterstopping

Sika® Injection-101 RC is a 2-part, polyurethane, low viscous, fast foaming, water-reactive injection resin. It cures to a dense flexible foam.

  • Foaming reaction only takes place in direct contact with water
  • Can be injected as a single component system
  • Free foaming expansion up to 40 times
  • Can be accelerated using Sika® Injection-AC10 in cold temperatures (< + 10 °C)
