Abstract
A member (1) for insertion into a borehole (9) in a receiving material (10) has an axially extending generally cylindrical hollow body (2) closed at its leading end (4) and open at its trailing end (5) and into which a mortar mass and anchor member can be inserted. The hollow body (2) has a sieve-like mesh wall. At least one circumferentially extending strip (8) of a compressible elastic open pore material is secured on the outside surface of the hollow body (2) for cleaning the surface of the borehole while the member is inserted into the borehole.
