LOGICBASE V-SL (S) is an unreinforced membrane of extruded PVC with a yellow face side and a black back side: the signal layer reveals damage during installation. It is used for underground parts of buildings, metro tunnels, underground car parks and inverted roofs, and also as an isolating layer for municipal solid waste landfills, sludge ponds, lagoons, artificial ponds and water storage tanks. The seams are welded with hot air. Elongation is 350% ±20%, flexibility on a bar is retained down to −45 °C, the membrane is seismic-resistant up to intensity 9, and its potential service life is estimated at 100 years.
