Drainage board is made of polystyrene or polyethylene 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. It is now made of polyvinyl chloride 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.

Water guiding and drainage properties: Both waterproof and drainage protection boards have concave convex hollow vertical

reinforcement structures, which can quickly and effectively discharge rainwater, greatly reducing or even eliminating the static water

pressure of the waterproof layer. Through this active water guiding principle, the effect of active waterproofing can be achieved.

Waterproof performance: Polyethylene (HDPE) polystyrene (PVC) waterproof and drainage protection board material itself is a

very good waterproof material. By adopting a reliable connection method, the waterproof and drainage board becomes a good

auxiliary waterproof material.

Protective properties: Waterproof and drainage protection boards can effectively protect structures and waterproof layers, and

resist various acids and bases in the soil as well as plant roots. When backfilling the basement exterior wall, it can protect the building

and waterproof layer from damage.
