Details description
Description:
Composite waterproof and drainage plate adopts a special craft plastic plate extrusion enclosed barrel shell protrusions formed concaveconvex
shell membrane, continuous, with three dimensional space and certain supporting height can withstand a long high, can not generate deformation.
The top of the shell covering geotextile filtering layer, to ensure that the drainage channel does not block due to external objects, such as particles
or concrete backfill.
Municipal Engineering: road subgrade, subway tunnel,landfill.
Construction:building a base or lower, underground outdoor wall, seepage prevention and insulation level.
Traffic engineering: highway, railway subgrade, dam and slope protection layer.
