Product Description: The drainage board is made of polystyrene (HIPS) or polyethylene plastic plate after punching cone penetration units made (or hollow cylindrical porous) from the top surface of plastic drainage board manufacturers phone, tapered projections access layer filter geotextile to prevent soil particles through, thus avoiding drainage obstruction, so that smooth drainage. The traditional use of brick tile drainage as a guide filter layer, the use of more pebbles or gravel as a filtration layer, the water discharged to the designated place. Now replace the pebbles treatment layer with a drain to drain is saving time, effort and energy saving investment, but also reduce the load of the building. Product Features: Good drainage system for normal use and life cycle of construction and civil engineering structures play an important role. HW type Drainage Board porous tubes with an effective drainage system sparse, long and short cylindrical drain and geotextile form a drainage system drainage board to form a water seepage, water and drainage systems. Laying procedure: 1. Clean the laying site of garbage, cement screed, so that there is no obvious bump at the site drainage board type, outdoor garage roof and roof garden need to find the slope of 2-5 ‰. 2. Green roofs and outdoor garage roof greening can be equipped with a porous pipe use, so can drain the water discharged into a local focus under or near the city sewer pipes. 3. Ground water seepage in the basement, on the basis of the above overhead floor, which is done in front of the floor drain is to do one round projections downward drainage board material left around the blind ditch, groundwater up the mountain, Natural seepage inflow through space around the blind ditch drainage board, and then through the blind ditch into the sump.
