High Strength Geocomposite Drainage Net for Reliable Subsurface Drainage

1. High-Efficiency 3D Drainage

The three-dimensional geonet core creates continuous drainage channels that quickly collect and discharge seepage, rainwater, and gases. Its high flow capacity helps reduce pore water pressure and maintain effective drainage under demanding site conditions.

2. Excellent Filtration

The bonded non-woven geotextile allows water to pass through while retaining soil particles. This helps prevent soil migration and drainage channel blockage, supporting stable drainage performance over the long term.

3. Dual Protection Function

The geotextile and geonet core work together to form a protective layer between different construction materials. The composite structure helps reduce the risk of puncture or mechanical damage to overlying materials, such as geomembranes, during installation and service.

4. Strong Chemical & UV Resistance

Made with durable PE and PP components, the drainage composite offers good resistance to common acids, alkalis, chemicals, and UV exposure. It can be used in a range of demanding civil and environmental engineering conditions.

5. High Compressive Strength

The robust three-dimensional core is designed to maintain its drainage structure under sustained loads. Even when covered by soil, aggregate, or other construction layers, it helps preserve an effective drainage path.

6. Excellent Creep Resistance

The reinforced composite structure helps limit deformation under long-term loading. This is particularly valuable in landfills, retaining structures, tunnels, and other projects where drainage performance needs to remain stable for many years.

7. Fast and Practical Installation

Supplied in rolls, the geocomposite drainage net is easy to transport, cut, lay, and connect on site. Its integrated drainage and filtration structure can also reduce the number of separate installation steps, helping simplify construction and save labor.

8. Space-Saving & Low-Maintenance Solution

Compared with conventional aggregate drainage layers, the geocomposite requires less installation space while providing an efficient drainage path. By combining drainage and filtration in one product, it also helps reduce the risk of clogging and the need for frequent maintenance.

1. Landfills & Tailingts Dams

Geocomposite drainage nets are installed between primary and secondary liner systems to form an efficient leachate collection and drainage layer. They help collect and discharge leachate quickly while reducing hydraulic pressure and protecting the integrity of the geomembrane liner system.

2. Tunnels & Underground Structures

Installed behind waterproofing membranes or between lining systems, the drainage composite creates a continuous path for groundwater to move away from the structure. This helps control water pressure, reduce the risk of water accumulation, and maintain a dry and protected tunnel environment.

3. Building Basements & Green Roofs

For basement walls, the drainage layer can be installed outside the waterproofing system to collect and redirect groundwater while reducing hydrostatic pressure. In green roof systems, it provides a drainage path above the waterproofing layer and helps protect the membrane from damage caused by overlying materials.

4. Sports Fields & Landscaping

Installed beneath the sub-base or growing layer, the geocomposite drainage net helps move excess water away from the surface. It reduces waterlogging, supports a more stable foundation, and helps maintain usable and well-drained sports fields, landscaped areas, and recreational spaces.

5. Retaining Walls & Reinforced Structures

Installed behind retaining walls, the drainage composite helps collect groundwater and direct it toward designated outlets. By reducing water pressure behind the wall, it can support overall drainage performance and help protect the structure over its service life.

6. Roads, Railways & Infrastructure

Used beneath roads, railways, and other paved structures, the drainage layer provides a controlled path for excess water within the subgrade or base layers. Effective subsurface drainage helps limit water accumulation and supports long-term pavement and structural performance.
