REGUPOL sound and drain 22 is a polyurethane elastomer mat with dimpled underside and laminated geotextile that combines impact sound insulation and drainage under floors exposed to water: balconies, terraces, loggias and external walkways.
The 15 mm dimpled profile leaves room for water to drain away while the elastic rubber reduces footstep noise by ΔLw 28 to 37 dB, depending on the floor finish. It also protects the waterproofing membrane (compatible with bitumen and EPDM membranes). Rolls of 10 × 1.25 m; traffic loads up to 50 kN/m².
