Rock Bolting

QPS provide Rock bolts for stabilising rock excavations where random unstable exterior rock is likely to fail. The rock bolt acts to confine the unstable rock by anchoring into a stable rock mass beyond.

The rock bolt comprises of a steel bar that is grouted or chemically anchored using epoxy resin into a drill hole beyond the unstable material. The rock bolt is then preloaded via a nut and plate on the rock surface.
