6759 CAN INVENTOR: PETER KAUFMANN INVENTION: HOSE-LIKE SEAL DEVICE FOR CONCRETE JOINTS AND METHOD OF FABRICATING A CONCRETE JOINT SEAL ABSTRACT OF THE DISCLOSURE A mesh hose bears upon a liquid pervious, for instance helical-spring shaped support body, and upon such mesh hose there lies a fleece hose. This structure is loosely placed in an external mesh hose portion. The fleece 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 loca- tions and can seal the same. The fleece hose successfully prevents the clogging of the device by concrete grout or the like.
