Backfilling in underground construction
MasterRoc's range of mine backfill technologies have been developed to provide the optimum balance of high early strength and sustainable long term strength, ensuring dimensional stability after placement by meeting (or exceeding) design fill performance requirements.
BASF's range of backfill admixtures includes specialized rheology modifiers, hydration control, and durability enhancers that can be either used alone or in a combination to improve backfill durability.
We push back the conventional physical limits with our innovative technologies such as hydration control, water reducers, superplasticizers, viscosity modifying admixtures (VMAs) etc., and depending on our customers' requirements, we can control and achieve retardation, acceleration, rheology control, modified viscosity, reduce yield stress and pumping pressures. Furthermore we can stabilize fines in the fill matrix and reduce slime run off, segregation and porosity, enhance strength development and optimize binder content.
