HDPE Drainage Boards Are Used For Construction Projects
Drainage Board
The plastic drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) as raw materials. The plastic bottom plate is punched into conical projections or stiffener convex points (or hollow cylindrical porous). It has undergone continuous innovation and research and development. The raw material has been greatly improved and changed. The compressive strength and overall flatness have been greatly improved.

Product Feature
The surface has a certain number and specifications of convex points, which can increase
the friction between the plate and the soil to prevent the soil from moving and falling off. At
the same time, the convex point on the drainage plate can also play a role in dispersing
pressure, reducing the water pressure inside the building and the bearing capacity of the
foundation, and protecting the building from being damaged.
