DELTA®-MS - B1 (flame retardant) for Tunnel Ceiling & Wall Application
DELTA®-MS B1 is equipped with highly effective flame retardants. It meets the stringent requirements of DIN 4102, Class B1 and is therefore ideally suited for drainage applications in tunnel construction projects with specific fire hazard regulations.
DELTA®-MS B1 (flame retardant) provides a reliable and effective seepage and drainage layer in tunneling construction projects.
Dimpled membrane made of special, high-density polyethylene and flame retardants.
When installed on the surface of tunnel walls or ceiling, DELTA®-MS B1 provides an effective drainage layer for seepage water emerging from the rock substrate.
