Drainage Board
The drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) plastic base plate that is stamped into conical protrusions or convex points with stiffening ribs (or hollow cylindrical porous), with a width of 3 meters and a length of 10 meters or 15 meters.
Drainage boards are divided into two series: rolls and sheets. They are used in garage roofs, roof gardens, and the upper or lower layers of building foundations. They can drain water, store water, and prevent roots from damaging the protective layer.
The drainage boards commonly used in construction are: self-adhesive PE drainage boards, plastic drainage boards, storage drainage boards, roll drainage boards, anti-seepage drainage boards, composite drainage boards, three-dimensional drainage boards, sheet drainage boards, etc.
