Many hard rock mines have ore rich reserves, contained in unmined area's, commonly referred to as sterilised ore. With the placement of backfill adjacent to these resources, our solutions can maximise the extraction of previously sterilised ore resources, with unique and well proven products and methodologies.
We offer > 18 years experience, proven application success rate, increased revenue profits and optimised control of mineral dilution.
“To date, five pillars have been consolidated allowing us to mine 116,000 ounces of gold earlier than planned and access an additional 23,000 ounces.”

Our FB200 low viscosity, high yield grout is used for many applications within underground mines. We have 20 years experience in using FB200 for stabilising rockfill to enhance stope extraction, constructing explosion rated ventilation seals, filling of large voids and constructing false pillars for pre-driven recovery roads.
We have developed variants for hostile conditions such as saline water, hot water and long distance pumping.
Typically pumped at a 2:1 water:powder ratio, FB200 can be used between 1:1 and 3:1 ratios depending on individual project requirements.
FB200 is supplied as a ready to use free flowing blended cementitious powder that only requires the addition of water in a suitable placing machine.
High yield, long life foaming grout primarily used for ventilation applications and cavity filling. Supplied as a ready to use free flowing blended cementitious powder that forms cement foam on mixing with water in a purpose designed placer.
Uses include explosion resistant ventilation seals, recovery of longwall face falls, backfilling behind steel sets, recovery of falls, rib stabilisation and general void filling.
