Drainage and Retention Board


The drainage and storage board features a professional mechanical design, with uniformly thick walls on its protruding structures and integrated reinforcing ribs, ensuring high compressive strength while maintaining excellent flexibility. It resists degradation, drains water effectively, and remains stable over time. After being installed via hot-melt welding, the board exhibits uniform resistance to plant punctures, as well as outstanding chemical resistance—specifically to acids and alkalis—and exceptional aging performance. This creates a robust, flexible protective barrier that seamlessly integrates with building waterproofing systems, keeping the waterproof layer securely enclosed in a controlled environment and significantly reducing the risk of premature aging. As a result, the service life of the waterproofing system is dramatically extended.


Detailed description

Product Introduction:

The drainage and storage board features a professional mechanical structure design, with evenly distributed wall thickness across its protruding ribs and integrated reinforcing ribs, ensuring high compressive strength while maintaining excellent flexibility. It resists degradation, drains water effectively, and remains stable over time. After being installed via hot-melt welding, the board exhibits uniform resistance to plant puncture, as well as outstanding chemical resistance—withstanding acids, alkalis, and environmental aging. This creates a robust, flexible protective barrier that seamlessly integrates with building waterproofing systems, keeping the waterproof layer securely enclosed in a controlled environment and significantly reducing the risk of premature aging. As a result, the service life of the waterproofing system is dramatically extended.

The unique concave-convex hollow rib structure of the drainage and storage board efficiently channels rainwater away, significantly reducing—or even eliminating—the hydrostatic pressure on the waterproof layer. This proactive water-conducting mechanism enables an effective, active waterproofing solution.

The drainage and water-retention board material itself is an excellent waterproofing material. By using a reliable, overlapping installation method, the board further enhances its effectiveness as a supplementary waterproofing solution.

Drainage and water-retention boards effectively reduce indoor noise. When used on floors or walls, drainage protection boards also provide excellent ventilation and moisture-proofing benefits.

Main applications:

Landscape Engineering: Garage Roof Greening, Rooftop Gardens, Football Fields, Golf Courses.

Municipal Engineering: Road Subgrades, Subway Tunnels.

Construction Engineering: Upper or lower layers of building foundations, interior and exterior walls of basements, as well as roof waterproofing and insulation layers.

Transportation Engineering: Highways, railway subgrades, embankments, and protective layers.

Strong technological capabilities and robust R&D expertise


Long-filament geotextile

Long-fiber geotextiles are nonwoven geosynthetic materials made from polyester (PET) or polypropylene (PP) long fibers, produced via needle-punching or thermal bonding processes. They feature high strength, corrosion resistance, and excellent water permeability and filtration capabilities, making them widely used in engineering applications such as roadways, railways, and water conservancy projects for separation, filtration, protection, and drainage purposes.

Short-fiber geotextile

Short-fiber geotextiles are nonwoven geosynthetic materials made from short polyester (PET) or polypropylene (PP) fibers, processed through a combination of carding, web formation, and needle-punching techniques. Compared to long-fiber geotextiles, these materials feature shorter fibers and lower production costs, making them ideal for applications where moderate strength is required alongside cost-effectiveness—in isolation, protection, and drainage filtration projects such as temporary roads, landfill liner systems, and other similar uses.

Soft-body volleyball

Soft revetments (flexible bottom protection systems) are made by weaving high-strength synthetic fibers—such as polyester or polypropylene—into a mesh-like base fabric, which is then filled with materials like gravel, concrete blocks, or geotextile bags as stabilizing loads. These flexible protective structures are fabricated through sewing or tying processes. They are primarily used in applications such as riverbed protection, coastal erosion control, and slope stabilization, where they help dissipate the impact of water flow, preventing soil erosion beneath the surface and ensuring the structural integrity of engineering projects.

Laminate Film Machine-Woven Fabric

The split-film filament woven fabric is produced by high-density weaving of flat filaments made from polypropylene/polyethylene through a specialized split-film process. It boasts high strength and excellent resistance to aging, making it widely used in engineering projects such as highways, railways, and water conservancy for reinforcement, isolation, protection, and filtration-based drainage—tasks that effectively enhance structural stability.

Long-filament woven fabric

Long-filament woven fabrics are produced using polyester (PET) or polypropylene (PP) filaments as raw materials, processed through a high-strength weaving technique. These fabrics feature a uniform and stable mesh-like structure, making them widely used in reinforcement, isolation, protection, and drainage applications for projects such as highways, railways, and water conservancy works. They significantly enhance the structural integrity and durability of these projects by improving their resistance to deformation.
