Mine Backfill

Mine stability after placement

Mine backfill technologies help to provide an optimum balance of high early strength and sustainable long term strength, ensuring dimensional stability after placement to meet or exceed design fill performance requirements. BASF’s range of MasterRoc backfill admixtures can help customers challenge conventional physical limitations by:

  • Improving backfill durability
  • Controlling retardation, acceleration and rheology
  • Modifying viscosity, reducing yield stress and pumping pressures.
