Golem is a two component injection product, intended for cavity filling, air and gas sealing and the consolidation of highly fractured strata. Golem is applied using a metering pump and mixing gun.

The mixing of resin and catalyst, in a volume ratio of 4 to 1, produces an immediate foaming reaction, followed by a rapid expansion of the product to as much as 30 times its original volume. After expansion Golem sets hard in just a few minutes. The special properties of Golem (rapid application, high expansion rate, high compressive strength, fire resistance and excellent antistatic properties) produce a cost effective, quick and safe cavity filling solution.


  • High expansion rate
  • Instant foaming action

  • Good compressibility
  • No flame propagation
  • Filling of cavities and roof falls
  • Erection of firewall at a safe distance
  • Crossing rock-fall zones in tunnels and mine workings
  • Rapid construction of stoppings
  • Injection of fractured strata and air leakage cavities
