Drainage Board (hdpe drainage board) - Shandong Traffic Engineering: highway, railway subgrade and pavement, dikes and revetment layer backflow drainage municipal engineering: road embankment, subway tunnel, landfill groundwater and surface water conductivity row building projects: building foundations upper or lower, basement and external wall, green roof drainage seepage and insulation layer greening projects: the garage roof green, roof garden, soccer fields, golf courses, beach and other building projects the construction of the drainage board cone (or hollow cylindrical boss shaped porous) plastic chassis is made of high impact polystyrene (HIPS). Conical projections (or hollow cylindrical porous), the top surface glued a filter layer non-woven fabric to prevent soil particles through, in order to avoid the obstruction of the pore smooth drainage. Drainage board of the advantages of a traditional drainage masonry tile as a guide filter layer, using more pebbles or gravel as a filtering layer, the water is discharged to the designated location. The drainage board replaced pebbles treatment layer to drain the province, effort and energy saving, saving investment, and to reduce the load of the building. Good drainage board drainage system has an important role in normal use and service life of the civil construction cycle and structures. Drainage board, drainage board porous tube composed of an effective the sparse drainage system, the a cylindrical drainage of the long and short board with non-woven to form a drainage system, and thus the formation of a system of seepage, water storage and drainage function.
