Application of Huwang drainage board Landscape engineering: garage roof greening, Roof garden, football, golf, beach Engineering Municipal Engineering: road subgrade, Metro Tunnel Construction: building foundation above or below ground, internal and external walls, roofing seepage proofing and thermal insulation layer Traffic engineering: highway, railway subgrade, dam and slope protection layer Tectonic Huwang drainage board Cone bosses (or hollow cylindrical porous) plastic floor, made of high impact polystyrene (HIPS) made of. Cone bosses (or hollow cylindrical porous) of the top surface of a layer of non-woven adhesive filter, to prevent the soil particles through the channel, so as to avoid congestion, the channel smooth drainage. Advantages of Huwang drainage board Traditional drainage system using brick tile as a filter layer, the use of more pebbles or gravel as the filter layer, the water is drained to the specified location. And now with the drainage plate to replace the cobblestone filter layer to drainage time saving, labor saving and energy saving, investment saving, and reduce the building...
