Product Overview

The 3D Composite Drainage Net is a high-performance geosynthetic solution engineered to efficiently manage both surface runoff and subsurface water flow in civil, environmental, and construction projects. Combining a robust three-dimensional polymer core with a nonwoven geotextile filter layer, this innovative system rapidly channels water away from critical structures, preventing waterlogging, soil erosion, and hydrostatic pressure buildup. Ideal for roads, landfills, green roofs, and sports fields, it ensures long-term drainage efficiency while reducing installation costs and environmental impact.

Key Advantages

1. Dual-Action Drainage

   • Surface Water Control: Rapidly diverts stormwater and runoff, preventing ponding and surface erosion.

   • Subsurface Drainage: Captures and redirects groundwater, relieving hydrostatic pressure on foundations and retaining walls.

2. High Flow Capacity

   • Hydraulic Conductivity: Up to 0.5 cm/s (ASTM D4716), outperforming gravel layers by 10x.

   • Clog-Resistant Design: Geotextile filter prevents soil ingress while maintaining optimal water flow.

3. Structural Integrity

   • Compressive Strength: 50–500 kPa (ASTM D1621) to withstand heavy loads from soil, traffic, or equipment.

   • UV & Chemical Resistance: Polypropylene/polyethylene core ensures durability in harsh environments.

4. Cost & Time Savings

   • Lightweight & Easy to Install: Reduces material transport and labor vs. traditional gravel systems.

   • Low Maintenance: No sediment removal or replacement required for 50+ years.

Applications

• Road & Railway Bases: Prevents frost heave and subgrade saturation.

• Landfill Leachate Management: Collects and channels contaminated liquids to treatment systems.

• Green Infrastructure: Roof gardens, urban drainage, and permeable pavements.

• Sports Fields & Golf Courses: Eliminates waterlogging, ensuring playability in wet conditions.

• Retaining Walls & Foundations: Relieves hydrostatic pressure to enhance structural stability.

Technical Specifications

• Core Material: High-density polyethylene (HDPE) or polypropylene (PP) 3D mesh.

• Geotextile Layer: Nonwoven polypropylene (100–300 g/m²).

• Thickness: 4–8mm (customizable).

• Flow Rate: 0.2–0.5 cm/s (ASTM D4716).

• Tensile Strength: 8–20 kN/m (ASTM D4595).

• Roll Sizes: 2–4m width × 30–50m length.

3D Composite Net vs. Traditional Drainage

Installation Simplified

1. Prepare Subgrade: Compact soil and ensure a 1–2% slope for drainage.

2. Roll Out Net: Place geotextile side facing upward; overlap edges by 300mm.

3. Secure & Connect: Use adhesive or mechanical fasteners for seams.

4. Backfill Immediately: Cover with soil or aggregate to protect from UV exposure.
