HW-PSD10 (103) Professional drainage board floor is made ​​of high impact and high compressive strength polystyrene (HIPS) with anti-Can resist long-term hypertension, no deformation. This long-term resistance to stress not only be able to withstand the weight of its load of concrete base plate, during construction and can withstand a inevitable external pressure and impact, such as vehicles, workers trample and the pouring of concrete momentum. Long base plate is not deformed, thus maintaining the original displacement.
On the floor of the filter layer of geotextile uses to ensure drainage channel is not blocked by foreign objects, such as granular or concrete backfill
