Definition and Material: Drainage boards are made from raw materials such as high-strength polystyrene (HIPS), high-density polyethylene (HDPE), or polyvinyl chloride (PVC), and are formed by stamping into a porous structure with conical protrusions, reinforcing ribs, or hollow cylinders.<\/p>\n
Classification: Drainage boards are available in both roll and sheet forms. Based on application, they can be categorized as those for plaza landscaping and basements, with common specifications including H20 and H25.<\/p>\n
Main Functions: Drainage boards feature a concave-convex hollow ribbed structure, enabling rapid and effective drainage of rainwater, reducing or even eliminating hydrostatic pressure on the waterproofing layer, achieving active waterproofing. Simultaneously, they protect structures and waterproofing layers, resist soil acids and alkalis and plant root penetration, and provide some sound insulation, ventilation, and moisture protection.<\/p>\n","protected":false},"excerpt":{"rendered":"
