Revolutionize Your Drainage Solutions with High-Performance Efficiency

Product Specification

Our 3D Composite Drainage Net is an engineered geosynthetic solution designed for superior water collection, conveyance, and pressure distribution in demanding civil, environmental, and construction applications. Combining a rigid 3D core with nonwoven geotextile filters, it delivers unmatched performance in subsurface drainage, replacing traditional gravel systems with a lightweight, cost-effective alternative.

Key Features & Benefits

1. Triple-Layer Performance:

   • High-Strength 3D Core: A unique dimpled or studded polymer (HDPE or PP) core forms an open channel network for rapid water flow, even under high loads.

   • Integrated Geotextile Filter(s): Thermally bonded nonwoven geotextile(s) on one or both sides prevent soil intrusion while allowing water to freely enter the core. Choose single-sided or double-sided filtration based on your project needs.

   • Protective Separation Layer: The geotextile also acts as a separator, preventing intermixing of soil layers and protecting the drainage core.

2. Exceptional Hydraulic Capacity:

   • High Flow Rate (Transmissivity): Maintains excellent in-plane water flow capacity (up to XX l/s/m under Y kPa pressure - insert specific test data) even under high compressive loads and long-term use.

   • Superior Drainage Efficiency: Rapidly collects and removes water, reducing hydrostatic pressure and preventing waterlogging.

3. Outstanding Mechanical Strength:

   • High Compressive Strength: Resists deformation and maintains flow channels under extreme soil pressures and dynamic loads (e.g., traffic, fill material). Typical compressive strength: XX kN/m².

   • Excellent Tensile Strength: Provides structural integrity during installation and service (Longitudinal: XX kN/m, Transverse: YY kN/m - insert specific data).

   • Puncture & Tear Resistance: Durable geotextile resists damage during installation and from sharp substrates.

4. Long-Term Performance & Reliability:

   • Clogging Resistance: Optimal geotextile pore size (O90 ~ ZZ microns - insert specific data) effectively filters fine particles while minimizing clogging potential.

   • Chemical & Biological Resistance: Resistant to degradation from soil chemicals, alkalis, acids, and microorganisms (HDPE/PP core).

   • UV Stabilized: Formulated for resistance to ultraviolet degradation during exposed installation periods.

5. Significant Project Advantages:

   • Cost Savings: Reduces or eliminates the need for expensive granular drainage layers (gravel/sand), lowering material, transport, and labor costs.

   • Faster Installation: Lightweight rolls are easy to handle, cut, and place, dramatically accelerating project timelines.

   • Space Efficient: Ultra-thin profile (typically 5mm-10mm core thickness) saves valuable vertical space compared to gravel drains.

   • Reduced Site Disturbance: Minimizes excavation requirements.

   • Consistent Quality: Factory-controlled manufacturing ensures reliable performance, unlike variable natural materials.

   • Environmentally Considered: Reduces quarrying of natural aggregates; lighter weight lowers transportation emissions.

Applications

• Landfill Drainage Layers: Leachate collection (base & cover systems), gas venting.

• Retaining Walls & Bridge Abutments: Back-of-wall drainage to relieve hydrostatic pressure.

• Tunnel & Underground Structures: Perimeter drainage, waterproofing protection layers.

• Green Roofs & Plaza Decks: Drainage layer beneath growing media or paving systems.

• Sports Fields & Landscaping: Subsurface drainage to prevent waterlogging and extend usability.

• Road & Railway Construction: Edge drains, separation/drainage layers in embankments and subgrades.

• Foundation Drainage: Around basements and footings.

• Pond & Canal Liners: Drainage/protection layer beneath geomembranes.

Easy Installation

1. Prepare a smooth, compacted subgrade free of sharp protrusions.

2. Unroll the drainage net with the geotextile filter side facing the soil/fill (double-sided can be placed either way).

3. Overlap adjacent rolls minimally [e.g., 100-300mm] and secure overlaps as recommended (tape, adhesive, or stitching).

4. Cover promptly with backfill material, taking care not to damage the geotextile. Use lightweight equipment initially.

5. Compact cover material in thin lifts.
