ABSTRACT:
A mesh hose bears upon a liquid pervious, for instance helical-spring shaped support body, and upon such mesh hose there lies a paper-like hose. This structure is loosely placed in an external mesh hose portion. The paper-like hose can be impregnated. If such sealing device is placed with closed ends into a concrete joint, which then is to be closed with concrete, the sealing device then can be drilled from the outside through the concrete and filled with a sealing compound or agent which penetrates through the wall of the device into untight or leaky concrete locations and can seal the same. The paper-like hose successfully prevents the clogging of the device by concrete grout or the like.
