DESCRIPTION
FLAGON BSL membrane is a non-reinforced, synthetic PVC-P membrane made by co-extrusion. It is highly resistant to attack by micro-organisms and perforation by roots. It is a different color on each side:
- the upper surface (light green), which accounts for less than 20% of the total thickness, forms the "signal layer".
- the underside (dark grey) is highly resistant to puncture and perforation by roots.
FLAGON BSL is not UV resistant. It’s also available FLAGON BSL/300, having a non-woven geotextile 300 g/m2 coupled on the lower face of the membrane.
CIVILROCK attaches the highest importance to the quality of its products. This is why we operate a quality assurance system according to ISO 9001 BSI certified.

PACKING AND STORAGE
INTENDED USE OR USES
FLAGON BSL is a two-colored membrane used as a waterproofing layer in civil engineering and building structures, such as:
- Tunnels and buried galleries
- Cut and cover tunnels
- Underground works
- Coverings of buried structures
- Underground car parks
The waterproofing membrane FLAGON BSL includes a thin coloured layer on the visible face of the membrane that allows a quick visual check of any damage occurred to the membrane during the application. This layer is called the "signal-to-layer".
FLAGON BSL membrane can be used as part of a single layer waterproofing system, compartmentalised or not, and in Flag Vacuum system. The sheets are welded together by applying hot air or using hot wedge, with manual or automatic welder. The welding can be made either with a track that with double track. The double track allow to perform a pneumatic test with air.
