ECOBASE V-ST PVC waterproofing membrane — textured, for two-layer systems

Roll materials and membranes

ECOBASE V-ST serves as the second layer in two-layer PVC membrane waterproofing of underground structures. One of its sides has a textured surface of profiled studs or embossing, and the system itself allows leak-tightness to be monitored during construction and service. The membrane is made of extruded PVC without reinforcement, elongates by 200% ±20%, retains flexibility on a bar down to −40 °C and is absolutely watertight at a pressure of 1 MPa for 24 h. Rolls of 20 × 2.15 m are packed in opaque film.
