Products Description

Geonet Drainage Composites The latest geosynthetic material introduced in the market showcases a unique composition. It comprises a three-dimensional geomesh core, complemented by needle-punched non-woven geotextiles affixed to both sides. The geomesh core showcases an intricately designed structure, featuring a prominent vertical rib and a diagonal rib positioned at the top and bottom respectively. One of the primary advantages of this material is its exceptional ability to swiftly drain groundwater from the surrounding area, making it highly suitable for road applications. Additionally, it boasts a remarkable pore-maintenance system that effectively prevents the passage of capillary water, particularly under heavy loads.
Products Usage

Application and characteristics of Geonet Drainage Composites
A layer is placed between the foundation and the bottom to facilitate the drainage of water and prevent capillary water from seeping through. This layer effectively integrates with the edge drainage system to enhance the road's longevity.
The aging of the road and the formation of cracks result in the infiltration of rainwater into the pavement. To mitigate this issue, one solution is to directly install a three-dimensional composite drainage network beneath the road surface instead of using a traditional drainage foundation. This innovative structure offers significant benefits by prolonging the lifespan of both rigid and flexible road systems alike.
3. Laying Geonet Drainage CompositesThe isolation role of the base can effectively prevent the entry of fine materials into the base. Additionally, the geonet allows a limited amount of aggregate base to enter its upper part, thus acting as a barrier. This barrier function also restricts the lateral movement of the aggregate base, similar to the reinforcement provided by a geogrid. The composite drainage network in many geogrids enhances the tensile strength and rigidity, thereby improving the foundation's support capacity. Overall, these limitations greatly contribute to the reinforcement and support of the foundation.
4. In northern climates, laying Geonet Drainage CompositesThe use of mesh in foundations can be a great solution to counter the effects of frost heave. When the freezing depth is exceptionally deep, placing the mesh in a shallow position within the foundation can effectively block capillary action. By doing so, the formation of ice crystals can be significantly reduced, thus eliminating the need to restrict traffic loads during the spring thaw in cold regions. This innovative approach not only helps alleviate the negative consequences of frost heave but also provides a practical way to ensure smoother transportation without compromising structural integrity.
5. Geonet Drainage Composites With its numerous advantages of superior drainage effect, rapid drainage speed, excellent load capacity, strong compressive ability, as well as its cost-effectiveness, the geocomposite drainage netting has become widely popular in engineering applications such as landfill and road reinforcement. This innovative product not only facilitates the laying and transportation of winding material but also provides robust reinforcement and protection. All these features make it a reliable solution for achieving exceptional drainage outcomes and perfect stability in diverse engineering projects.
