With multi-utility openings for buildings without a basement (e.g. by Hauff-Technik or DOYMA), builders can safely route all the necessary supply utilities through the floor slab. Although this is a high-quality opening solution, it must be connected to the floor slab while being airtight and moistureproof at the surrounding flange.

Our MultiUtilitySEAL sealing collar solves the connection problem in no time with its adhesive flange on the floor slab. The elastomer flange fits precisely into the shape of the plastic housing. The butyl strip is a special feature that offers additional air and moisture protection.
