PLASTFOIL GEO — PVC membrane for waterproofing foundations and tunnels

PLASTFOIL GEO is a two-layer unreinforced membrane of plasticised PVC with a bright signal top layer, without UV protection. It is laid for waterproofing foundations and underground structures, cut-and-cover and bored road and railway tunnels, underground car parks, utility tunnels and inverted roofs; there is a radon resistance report and a frost-resistant version. Nominal tensile strength is 17 MPa, elongation at break is 300 and 320% lengthwise and crosswise. The sheets are welded by machine with a single or double seam, and the double seam is tested with air pressure.
