Tunnels & Aqueducts

Polisystem would like to introduce Polisystem Sub N materials for use in underground conditions. Polisystem Sub N membranes are ideal for use as barriers against fluids during construction of tunnels and underground structures and have been designed to suit underground conditions.

Polisystem Sub N is a waterproofing membrane without reinforcement produced by co-extrusion of Fortuline Golyolefin alloy. The upper and lower surfaces are coloured differently so that the integrity of the membrane layer can be monitored more easily during installation and service life.
