3D Composite Drainage Geonet is an advanced geosynthetic drainage material designed to provide efficient water flow, filtration, and protection in engineering applications. It combines a three dimensional HDPE geonet core with nonwoven geotextile bonded on both sides, forming a multifunctional drainage system.
This structure integrates filtration, drainage, and protection into one product. The geotextile layer prevents soil particles from entering the core, while the geonet ensures continuous water flow even under high compressive loads.
Compared with traditional sand and gravel drainage systems, this composite material significantly reduces installation time, material cost, and labor requirements. It also provides more consistent drainage performance and long term stability.
The unique 3D structure allows the product to maintain its thickness under heavy loads up to 3000 kPa, ensuring long lasting drainage capacity. It is widely used in landfill leachate collection systems, roadbed drainage, tunnel lining drainage, and slope protection projects.
