SikaFix®-501

Silicate based, 2-component fast curing and foaming injection resin for heading face stabilization and void filling in tunnelling and mining

SikaFix®-501 is a quickly foaming resin based on silicate with short reaction times.

  • High free-foaming factor, up to 35 times by volume
  • Also foams on contact with water
  • Very fast curing
  • Foam with a fine cellular structure
  • Easy application due to the mixing ratio of 1:1 by volume
  • Cured foam can be cut almost immediately
  • High penetration ability
  • Low initial viscosity
  • CFC and halogen-free
  • Solvent-free

Usage

SikaFix®-501 is used for preventive securing and stabilization of heading faces in tunnels and mines, plus for the rapid filling of voids and cavities. SikaFix®-501 is also used for stabilizing unstable ground and loose rock in cracks and crevices etc. It is suitable for sealing dry, damp and water-bearing cracks. The cured / hardened foam is ready for cutting and boring immediately.
