The rock bolt ,as described here, is a standard Permanent Ground Anchor . Both the bond between the steel strands and the casing and the bond between the casing and the surrounding ground are provided by the backfill grout as described. The reliability of the system hinges on the efficiency of the shrink compensating grout additives, which are expected to avoid the formation of a gap at the two interfaces upon completion of grout curing.
