Composite Drainage Network 3d Road Base Geonet 3d Composite Drainage Geonet Compound Net Composite Geomat
Three-Dimensional Composite Drainage Network
The three-dimensional composite drainage network is an advanced geosynthetic material designed for efficient drainage and foundation reinforcement. Its core consists of a 3D geonet made from high-density polyethylene (HDPE), featuring thick vertical ribs and inclined ribs at the top and bottom. This structure enables rapid drainage of surrounding water, such as beneath roads or other infrastructure.
On both sides of the geonet core, needle-punched nonwoven geotextiles are laminated, forming a composite with three layers. The geotextiles can be made from needle-punched PET or PP nonwoven fabric, or thermally bonded continuous filament nonwoven geotextile, providing excellent filtration and separation properties.
The system includes a pore maintenance mechanism that effectively blocks capillary water under high loads, preventing water accumulation while maintaining drainage. Additionally, this composite material serves as an isolation layer and reinforces the foundation, improving overall soil stability and structural performance.
Specifications:
Product name: three dimensional composites drainage network.

Tri-dimension composite geonet has the property of geotextile (filtration function) and geonet (drainage and protection function), it can provide a function system: filtration-drainage-protection. The core of net with its unique tri-dimension structure can bear high compression load in construction and remain certain thickness, provide good water conductivity.
1. The drainage ability is strong, can withstand the long-term high load
2. The high tensile strength and shear strength of the pit
3. To reduce the probability of the geotextile is embedded in the network core, can protect the long-term stability of the rate of water.
4. The three-dimensional composite drainage net can withstand more than 2000kpa compression load.
5. Far greater than the ordinary drainage network resilience.
