The Ecoguss base body is used in combination with an attachment piece for point drainage, and is equipped with a removable odor trap, and a protective cover for the construction period. The recyclable composite material Ecoguss meets the highest noise protection requirements, is temperature-resistant, resistant to aggressive media, and has a permanently corrosion-free surface. It is also briefly flammable from 100 to 400 degrees Celsius. The glued flange with bolts and screws made of stainless steel is used for the clamping or welding of bitumen and polymer bitumen sheets as well as for polymer and elastomer sealing sheets. Only the sealing sheets tested by the manufacturer may be used for watertight seals. The outlet socket is suitable for connection to SML cast iron pipes. Separate equipotential bonding is not necessary.
