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. Master Builders Solutions' 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
