3D composite drainage geonetThe needled non-woven geotextile composite three-dimensional geomesh core is a recently developed drainage material. Its composition includes a structure that consists of a geo-mesh core embedded within a needled non-woven geotextile.
3D composite drainage geonet，The geonet is designed with a core thickness ranging from 5 mm to 8 mm. It can reach a width of up to 4 meters, and its length can be customized as per the user's needs. The geotextile used can be either a staple fiber geotextile or a long filament geotextile, and it typically weighs around 200 grams.
Product features: 3D composite drainage geonet
The combination of geotextiles and drainage networks creates an overall functional effect that involves filtration, drainage, and maintenance. This innovative solution integrates the filtration effect of geotextiles with the reinforcement impact of the drainage network, providing excellent performance and protection. The synergy of both technologies offers an efficient and cost-effective way to ensure long-term stability and sustainability of infrastructure projects such as roads, railways, and dams. By using this filtration-drainage-maintenance approach, we can optimize the durability and lifespan of these projects, saving time and money while ensuring safety and quality.
The unique 3D composite drainage geonetIn the process of use, it is essential for the material to withstand high pressure load while ensuring quick drainage. Additionally, it should possess remarkable resistance to corrosion, acids, and alkalis, while also serving as an effective isolator and reinforcing foundation.
