HDPE Geotextile Geonet Composite for Drainage

The three-dimensional composite drainage geonet is an innovative geosynthetic material composed of a high-density polyethylene (HDPE) plastic mesh as its core, with one side bonded to a filter geotextile and the other side to an impermeable geomembrane. This material is uniquely designed with a pore maintenance system that can block capillary water under high loads and serves as an isolation and foundation reinforcement. It is primarily used for drainage in landfill sites, roadbeds, and tunnel walls, effectively replacing traditional layers of sand and gravel. When laid between the foundation and subbase, it can rapidly drain water, block capillary water, and effectively integrate into the edge drainage system, shortening the drainage path and time. Additionally, it prevents fine materials from the subbase from entering the foundation, serving as an isolation layer. In transportation infrastructure projects, the three-dimensional composite drainage network plays a crucial role in the drainage system, impacting the safety and service life of the project.

Product Details

Advantages :

Excellent drainage performance:

With its unique mesh structure and high porosity, the three-dimensional composite drainage network can quickly collect and discharge water, effectively reducing water levels and pressures in the soil.

Compared to traditional drainage materials, it offers higher drainage efficiency, minimizing water accumulation in the soil, preventing soil liquefaction, foundation settlement, and other issues

Good compression resistance:

The mesh structure of the three-dimensional composite drainage network can disperse pressure, exhibiting excellent compression resistance.

It remains stable and durable under heavy loads or vehicle compaction, ensuring the stability and longevity of the drainage system.

Environmental friendliness and pollution-free:

The three-dimensional composite drainage network is made from high-molecular materials that are non-toxic and harmless, posing no threat to the environment.

It does not release harmful substances during use, protecting the soil and groundwater from contamination. It is also recyclable, aligning with green and environmentally friendly principles.

Simple and fast installation:

Made from lightweight materials, the three-dimensional composite drainage network is easy to transport and install.

During construction, simply lay the drainage network in the area requiring drainage and secure it with minimal effort. This significantly reduces construction time and costs.

Stable long-term performance:

The three-dimensional composite drainage network exhibits excellent weather resistance and aging resistance, maintaining stable performance over long periods in various harsh environments.

It is resistant to ultraviolet rays, oxidation, and microbial corrosion, ensuring long-term drainage performance and service life.

Barrier and filtration function:

The fibers and membranes of the drainage network filter out fine particles, preventing soil particles from being washed away and preventing soil infiltration and downward movement, maintaining soil stability.

Consolidation and reinforcement:

The three-dimensional composite drainage network enhances the shear strength and bearing capacity of the soil. Through the interaction between the soil and the grid, it improves the stability and safety of the foundation.

Applications:

Road and Transportation Engineering:

Drainage systems for highways, railways, and other roadbeds: The three-dimensional composite drainage network effectively drains excess water, accelerating the drainage process and protecting road structures for longer service life.

Drainage for bridges and tunnels: It is used to collect and discharge groundwater in bridge and tunnel constructions, preventing moisture from eroding and damaging the structures.

Landfill and Environmental Engineering:

Drainage in landfills: The three-dimensional composite drainage network is placed at the bottom and sides of landfills to effectively collect and drain leachate, preventing the spread of pollutants.

Industrial solid waste dumps and mining tailings ponds: It also plays an important role in drainage and environmental protection in these projects.

Water Conservancy and Civil Engineering:

Drainage control in rivers, lakes, and embankments: The three-dimensional composite drainage network is used in drainage systems for water conservancy projects to effectively control water levels and prevent flooding.

Basement drainage: In basement and underground construction projects, it collects and discharges groundwater to maintain a dry and stable environment.

Landscaping and Greening Projects:

Protection of artificial wetlands and greening systems: The three-dimensional composite drainage network collects and discharges excess water in artificial wetlands and greening systems, maintaining an optimal growing environment for plants.
