Flexible synthetic waterproofing membrane in plasticised vinyl chloride (PVC-P), obtained through a co-extrusion
process. Single layer membrane in two-colour version (signal-layer). The different colours on the two sides, light on
the exposed surface and dark behind, make it possible to immediately identify any damage to the membrane during
installation. Characterised by high mechanical resistance, resistance to the attack of micro-organisms in soil, to roots, to explosion, to low temperatures.
