Drainage Cell

Plastic drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) as raw materials, and the plastic bottom plate is punched into conical protrusions or reinforcing ribs with convex points (or hollow cylindrical porous). Through continuous innovation and research and development of raw materials, it has been greatly improved and changed. Now it is made of polyvinyl chloride (PVC) as raw material, and its compressive strength and overall flatness have been greatly improved. The width is 1-3 meters and the length is 4-10 meters or more.
