Detail

Product introduction:

Honeycomb waterproof sheet performance: waterproof sheet in the role of rock engineering is mainly for seepage control and isolation, but also play a strengthening and protection role. Chemical corrosion resistance, aging resistance, good wear resistance, low temperature resistance, easy construction without pollution, strong puncture resistance.

Cellular waterproof board uses.

1、Tunnel, subway, underground foundation works of prevention, drainage

2, butt joints, rock circle joints, prevention, drainage

3、Walls, foundations, floors, roofs of the prevention and drainage

Executive standard: GB18173.1-2012-YS
