LOGICBASE V-SL (W) PVC waterproofing membrane — for foundations and tunnels

Roll materials and membranes

LOGICBASE V-SL (W), an unreinforced membrane of extruded PVC, is designed for waterproofing underground parts of buildings, metro tunnels, underground car parks and inverted roofs. It is also laid in municipal solid waste landfills, sludge ponds, artificial ponds and water storage tanks. The membrane is absolutely watertight at a pressure of 1 MPa for 24 h, does not let roots through, has low permeability to radon and methane, and in 15% solutions of salts, alkali and acids changes its properties by not more than 10%. The yellow-and-black signal layer reveals damage during installation.
