The 3D Composite Drainage Net is an advanced geosynthetic material engineered for high-performance drainage, filtration, and soil stabilization. Combining a robust three-dimensional polymer core with permeable geotextile fabrics, it delivers superior hydraulic conductivity and structural durability. Ideal for civil, environmental, and infrastructure projects, it replaces traditional granular drainage systems, reducing costs and enhancing efficiency.
High Drainage Capacity
The 3D polymer core features a unique structure with vertical ribs forming efficient drainage channels and cross-ribs preventing geotextile embedding. This design ensures rapid water flow even under high pressures, with a permeability rate up to 2500 m²/day (under 720 kPa load).
Equivalent to 1 meter of gravel drainage in performance, significantly reducing material and transportation costs.
Exceptional Mechanical Strength
Tensile Strength ≥36.5 kN/m, ensuring resistance to deformation under heavy loads (e.g., soil pressure, traffic loads).
Compressive Resistance: Withstands up to 3000 kPa pressure while maintaining >60% thickness after long-term loading (10,000 hours under 1200 kPa).
Integrated Filtration and Protection
Dual-layer non-woven geotextile (typically ≥200 g/m²) acts as a filter, preventing soil clogging while allowing water passage.
Permeability Coefficient ≥0.2 cm/sec, ensuring optimal filtration and resistance to chemical/biological degradation.
Long Service Life and Durability
Made from UV-stabilized HDPE with carbon black additives for resistance to corrosion, acids, alkalis, and weathering.
Maintains performance in harsh environments (e.g., landfills, tunnels) for decades.
Easy Installation and Cost Efficiency
Lightweight and flexible rolls (standard widths: 2–4 m; lengths: 30–50 m) enable quick deployment without heavy machinery.
Reduces construction time and labor costs by >30% compared to traditional methods.
Landfill Systems
Leachate collection, gas drainage, and detection layers.
Transportation Infrastructure
Road/railway subgrade drainage, slope stabilization, and tunnel waterproofing.
Environmental Projects
Retaining wall back drainage, erosion control, and green roofs.
Urban Construction
Foundation drainage, sports fields, and plaza drainage systems.
Surface Preparation: Clear debris and level the subsoil.
Unrolling: Place the net with the geotextile side facing the soil. Rolls should be perpendicular to the drainage direction.
Joining: Overlap adjacent rolls by 10–15 cm. Secure the网芯 (core) with plastic clips or polymer straps every meter.
Backfilling: Cover with soil/aggregate without damaging the geotextile.
Certified Quality: Complies with ASTM, ISO, and GRI standards.
Customizable: Available in thicknesses (5–15 mm), widths (up to 4.8 m), and geotextile types (e.g., polypropylene, polyester).
Technical Support: Project-specific design and installation guidance.
Q: How does it compare to gravel drainage?
A: It offers equivalent performance at 1/10 the weight and volume, reducing carbon footprint and costs.
Q: Can it be used in steep slopes?
A: Yes, its flexibility allows installation on slopes up to 45° without slippage.
Q: What is the lifespan?
A: >50 years under standard conditions due to HDPE’s inert properties.
Packaging: Rolls wrapped in protective PE film.
Sample Availability: Provided upon request.
Lead Time: 7–15 days after order confirmation.
