Product Introduction:
Plastic drainage boards are made by pressing plastic base plates made of high-impact polystyrene (HIPS) or high-density polyethylene (HDPE) through punching to form conical protrusions or reinforced ribs (or hollow cylindrical multi-holes). Through continuous innovation and research and development, the raw materials have been greatly improved and changed. Now they are pressed from () as raw materials, with significant improvements in compressive strength and overall flatness. The width is 1 to 3 meters, and the length is 4 to 10 meters or more.

Performance features:

Water drainage and guiding property
The concave-convex hollow ribs structure that all the waterproof and drainage protection boards have can quickly and effectively guide out rainwater, greatly reducing or even eliminating the hydrostatic pressure on the waterproof layer. Through this active water guiding principle, an active waterproofing effect can be achieved.
Waterproof performance: Polyethylene (HDPE) and polystyrene (PS) waterproof and drainage protection board materials themselves are excellent waterproof materials. By adopting reliable connection methods, the waterproof and drainage board becomes an excellent auxiliary waterproof material.
The protective and shielded drainage protection board can effectively protect structures and waterproof layers, and resist various acids and alkalis in the soil as well as root pricks from plants. When backfilling soil against the exterior walls of underground structures, it can safeguard buildings and waterproof layers from damage.
Sound insulation, ventilation and moisture-proof functions:
Laboratory data shows that polyethylene (HDPE) waterproof drainage protection boards can effectively reduce indoor noise by 14 decibels at 500 Hz, demonstrating a significant noise reduction and sound insulation effect. When used on the ground or walls, the waterproof drainage boards can also provide excellent ventilation and moisture-proof performance.

Applications and Uses:
Landscape Engineering: Garage roof greening, roof gardens, vertical greening, sloping roof greening, football fields, golf courses.
Municipal Engineering: Airports, road subgrades, subways, tunnels, landfill sites.
Building Engineering: Upper or lower layers of building foundations, interior and exterior walls and floor slabs of basements, waterproofing and insulation layers for roofs and floors.
Water Conservancy Engineering: Seepage prevention for reservoirs, water storage tanks, artificial lakes.
Transportation Engineering: Road and railway subgrades, embankments and slope protection layers.
