FLAGON BSL is a two-colour membrane used as a waterproofing layer in civil engineering and construction works such as:

• Tunnel and bored tunnels
• Underground tunnel roofs
• Underground works
• Roofing of underground works
• Underground car park

The FLAGON BSL waterproofing membrane has a thin coloured layer on its visible side to allow the rapid visual inspection of any membrane damage that might have occurred during the works. This layer is called the “signal layer”.
The FLAGON BSL membrane can be used in single-layer waterproofing systems, compartmentalised or otherwise, and as a waterproofing layer in Vacuum Flag systems.
The sheets are normally sealed using a hot air or hot wedge system, with a manual or automatic welding machine. Both single-track and double-track welds can be made, allowing for pneumatic testing.
