Rapid strength gain


Excellent pumpability


  • Rapid strength gain reduces the likelihood of bed separation or slippage of strata.
  • Rapid strength gain reduces down-time before drilling/blasting can recommence.
  • Non-shrink, unique expansion system compensates for shrinkage
  • Excellent pumpability
  • Economical, high strength gain at significantly lower cost compared to resin grouts
  • Durability, excellent in high saline and/or acidic ground water
