ABSTRACT:
A grouting anchor to be inserted in a pre-drilled hole (3) comprises a stopper (4) sealing the drill hole at its orifice, this stopper being provided with an inlet opening (6) for the grouting compound.
In order to be able to monitor from the outside the formation of the plug of grouting compound, the stopper (4) is equipped with a backflow opening (7) for grouting compound, this opening terminating into a forward, air-permeable collecting cage (8) which latter, after curing of the grouting compound, can be separated from the stopper (4).
