dry shotcrete.

  • Alkali-free, avoiding additional leaching and pollution of alkalis and pollution of ground and surface water.
  • When correctly used, marginal reduction of shotcrete strength.
  • Reduction of rebound.
  • Easier overhead spraying by improved bond of shotcrete to rock and concrete.
  • Reduction of dust formation.
  • Chloride-free, suitable for steel reinforced shotcrete and substrates.
