“No more waiting for cementitious grout to cure. Now we can just drill, inject and mine!” – Jolyon Jardine, Mine Manager, Kanmantoo Copper Mine, SA.

Case Study: Kanmantoo Copper Mine

Recently, at the Kanmantoo Copper Mine in South Australia, MasterRoc RBA 380, our fast-reacting, instantly thickening anchoring resin, was successfully injected into a dozen 9-metre self-drilling anchors (SDAs).

Challenges with Traditional Cementitious Grouts

Typically, cementitious grouts are used for deep embedment support systems such as cable bolts and coupled SDAs. These generally have a longer re-entry time due to the subsequent curing rate, with most operations waiting up to 12 hours before advancing.

Innovative Solution: MasterRoc RBA 380

By choosing MasterRoc RBA 380, contractors are now able to continue excavating safely almost instantly, as the injection resin reaches >35 MPa in just 5 minutes.
