Drainage board is made of polystyrene 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. 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

The concave convex hollow vertical reinforcement structure of waterproof and drainage protection boards 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, 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.

Protection and Protection

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.

Sound insulation, ventilation, and moisture prevention functions:

Polyethylene (HDPE) and polyvinyl chloride (PVC) waterproof and drainage protection boards can effectively reduce indoor noise

levels of 14 decibels and 500Hz, and have significant noise reduction and sound insulation functions. Waterproof water guide boards

can also provide good ventilation and moisture resistance when used on floors or walls.
