Product Description
Reinforced Composite Drainage Geonet
A multi-functional composite material engineered for highway and railway projects, integrating drainage, filtration, and reinforcement capabilities in a single solution.
This advanced geonet is optimized from standard composite drainage geonets by increasing geonet core thickness and enhancing non-woven geotextile tensile strength. It provides rapid seepage water discharge while improving foundation bearing capacity, stress distribution, and preventing foundation deformation.
Manufacturing Process
High-quality HDPE material (density ≥ 0.94 g/cm³) forms the geonet core, with increased vertical ribs and inclined supports for enhanced compressive strength and drainage capacity. Upper and lower non-woven geotextiles use high-strength polypropylene fiber processed by needle punching to improve tensile strength and filtration performance.
The composite process employs hot-melt bonding + needle punching technology, creating a firm connection between geonet core and non-woven geotextile that integrates drainage, filtration, and reinforcement functions.
Technical Specifications
Complies with ASTM D6391-17, EN ISO 10318:2010, and GB/T 17642-2011 standards:
| Parameter | Specification |
|---|---|
| Geonet Core Thickness | 8-25 mm |
| Non-woven Geotextile Weight | 100-300 g/m² (per layer) |
| Longitudinal Tensile Strength | ≥ 30 kN/m |
| Transverse Tensile Strength | ≥ 30 kN/m |
| Compressive Strength | ≥ 300 kPa (no obvious deformation) |
| Drainage Capacity | ≥ 0.5 m³/(m*h) (under 200 kPa pressure) |
| Elongation at Break | ≤ 15% |
| Wear Resistance | ≥ 500 cycles (no damage) |
Application Scenarios
- Highway and railway projects including subgrade drainage for highways, railways, and bridge approaches
- Airport runways and freight yards for rapid seepage water discharge and enhanced subgrade bearing capacity
- Prevention of subgrade softening and settlement in various infrastructure projects
- Slope protection drainage systems to ensure slope stability and structural integrity
