Device for sealing a structural joint has elastic sealing element clamped to building and with co-extruded compensating element facing building to swell up on contact with water

摘要

The sealing device has an elastic sealing element (D) which is clamped by a flange to at least one side of the joint and has pointing at least in part to the building structure (14) a co-extruded compensating element (20) which swells up on contact with water as a result of its material additives such as bentonite, organic resin, hydrophilic polyurethane resin. The additives can be super absorbers with nanostructure. The sealing element is made from thermoplastics materials such as polyvinyl chloride, polyethylene, polypropylene.
