Before leading pipelines or cables through external walls being above or below ground level, through ceilings or in so-called sheath tubes, it has to be made sure that the lead-through areas are permanently sealed. Neither pushing water nor gas may permeate by the lead-through of the building resp. the protective pipe sealing.
WIDOS Ring-Seal lead-throughs of buildings and sealing inserts enable simple, quick and clean lead-throughs of pipelines and cables through walls, ceilings and sheath tubes. The sealing inserts are designed in pressure-tight form in two steps (20 mWS / 50 mWS) and additionally prevent a transmission of heat and sound.
