Plastic drainage board


Plastic drainage boards, also known as plastic drainage strips, come in various shapes, including wavy and accordion-like designs. At their core is an extruded plastic core board, which serves as the structural backbone and primary drainage channel. This core features a parallel cross-sectional design, with both sides wrapped in non-woven geotextiles that act as filtration layers. The core provides essential support while simultaneously directing water absorbed by the filter layers upward and out of the system. As a result, these drainage strips offer an ideal vertical pathway for effective drainage consolidation in saturated cohesive soils such as silts, clayey soils, and fill materials—significantly reducing the time required for soft soil stabilization and consolidation.


Detailed description

Product Introduction:

Plastic drainage boards, also known as plastic drainage strips, come in various shapes, including wavy and accordion-like designs. At their core is an extruded plastic core board, which serves as the structural backbone and primary drainage channel. This core features a parallel cross-sectional design, with both sides encased in non-woven geotextiles that act as filtration layers. The core itself provides essential support while simultaneously channeling water that has seeped through the filter layers upward. As a result, these drainage strips create efficient vertical pathways for dewatering and consolidation processes, making them ideal for treating soft foundations composed of saturated cohesive soils such as silts, clays, and fill materials—significantly reducing the time required for soft soil consolidation.

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.
