Description
A synthetic membrane of plasticized PVC, manufactured by co-extrusion, producing a single layer membrane with different colour surfaces. The upper signal layer is coloured white and the lower surface black, which enables damaged areas to be immediately identified.
Features and benefits:
- Displays high mechanical resistance and is resistant to roots, washout water action, low temperatures and eddy currents.
- The liner can also be supplied with inherent fire resistance to Class ‘B’ in accordance with DIN 4102/1.
- Joints are fixed/ sealed by welding. Laps are dependent on location and welding method.
