3D Geomesh Plastic Geonet Composite Drainage Net For Highway Projects Flexible Drainage System
Description of 3D Composite Drainage Net
3D composite drainage geonet is made of a unique tri-dimension geonet crated geotextile on the boat sides. It has the property of geotextile (filtration function)and geonet (drainage and protection)and provide a function system"Filtration-Drainage-Protection".
The core of net with its unique tri-dimension structure can bear higher compressing load in construction and remain the certain thickness provide good water conductivity.

3D Composite Drainage Net Advantages compared to traditional materials
Performance | Composite drainage net | Traditional gravel layer |
Drainage efficiency | Equivalent to 1 meter thick gravel layer | Requires thicker layer (2-3 meters) |
Stress resistance | 3000kPa | Easy to be compressed and deformed |
Construction costs | Reduce by 30%-50% | Requires a lot of manpower and transportation |
Life | More than 50 years (corrosion resistance) | Easy to age and clog |
Application scenarios of composite drainage nets
Composite drainage nets are widely used in many engineering fields due to their high-efficiency drainage, pressure resistance and anti-filtration characteristics.
Traffic Engineering
1. Road Drainage
- Roadbed Drainage: laid at the bottom of the roadbed or under the ballast layer, quickly draining groundwater and surface seepage, reducing roadbed settlement and mud bubbling, and extending the life of the road.
- Tunnel Drainage: blocking the rise of capillary water, preventing frost heave damage, and protecting the tunnel structure.
- Railway Drainage: removing water from the ballast layer, preventing track deformation, and enhancing the bearing capacity of the roadbed.
2. Highways and Municipal Engineering
- Used for highway roadbed drainage, reducing the thickness of the base layer and improving the bearing capacity;
- Combined with green belts in municipal roads to form an integrated drainage system to improve rainwater collection efficiency.

Environmental protection and municipal engineering
1. Landfill
- Drain leachate, groundwater and biogas, protect the anti-seepage membrane and prevent the spread of pollution.
2. Sponge city construction
- Rainwater garden and green space: laid at the bottom to form a drainage layer to prevent the soil from being too wet and promote plant growth;
- Roof greening: pre-buried drainage pipes, collect rainwater and introduce it into the recycling system to reduce roof erosion.

Water conservancy projects
1. Reservoirs and slope protection
- Remove water from the slope to prevent water pressure from damaging the structure and enhance stability.
2. Underground structures
- In underground garages, subway tunnels and other scenes, it is laid on the side walls and bottom to quickly drain the water.

All products are loaded into containers by trained factory personnel under real-time supervision to ensure proper handling and maximize transport safety. This process helps minimize damage during transit and ensures your goods arrive in excellent condition.
