Flagon BSL
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.

Flagon BSL displays high mechanical resistance and is resistant to roots, washout water action, low temperatures and eddy currents, typical applications include lining of natural and artificial tunnels and as a humidity screen for foundations.

The liner can also be supplied with inherent fire resistance to Class ‘B’ in accordance with DIN 4102/1. Consult manufacturer for details.

Joint laps:

Joints are fixed/ sealed by welding. Laps are dependent on location and welding method. Consult manufacturer for specific recommendations.
