HDPE Plastic Dimple Drain Board
The bottom plate of the drainage board is made of HIPS and HDPE, which can resist long-term high pressure. There will be no deformation. This long-term compression resistance can not only withstand the weight and load of the concrete floor, but also withstand the external pressure and impact force that cannot be avoided during the construction period, such as vehicles, workers and concrete pouring impulse. Keep the bottom plate out of deformation for a long time, so as to maintain the original displacement. The filter layer soil fabric on the bottom plate is used to ensure that the drainage channel is not blocked by foreign matter, such as backfill soil particles or concrete.
