Abstract

Device and method for reinforcement and sealing a rock wall, which device comprises a reinforcement bar (1) adapted to be introduced into a bore hole (30) in the rock wall, into which bore hole a filling material (31) is intended to be injected, and also comprises a non-return valve (4) for the filling material. The device further comprises a tubular shaped expander (20) for anchoring the device in the rock wall, which expander, before the expansion, exhibits at least one, preferably at least two, axially extending indentations (22), whereby the expander has a peripherical length in its cross-section which exceeds the circumference of the bore hole (30), but has a largest diameter which is less than the diameter of the bore hole, said expander (20) being arranged to be expanded and thereby plastically deformed essentially without its peripherical length increasing, at anchoring of the device in the rock wall.
