<p>6759 CAN INVENTOR: PETER KAUFMANN INVENTION: HOSE-LIKE SEAL DEVICE FOR CONCRETE JOINTS AND METHOD OF FABRICATING A CONCRETE JOINT SEAL 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 locations and can seal the same. The fleece hose successfully prevents the clogging of the device by concrete grout or the like.</p> |
