High-Flow Core for Superior Leachate Drainage in Landfills & Efficient Water Management in Green Roofs

I. Product Overview
This high-performance 3D Composite Drainage Net is a versatile geosynthetic solution designed for two critical applications: landfill drainage layers and roof gardens. Its unique three-dimensional structure features a rigid, geometrically patterned core thermally bonded to a nonwoven geotextile filter fabric. In landfill engineering, it serves as a primary or secondary leachate collection layer, providing an unparalleled in-plane flow capacity to quickly channel leachate away from the geomembrane liner, protecting its integrity. In green roof systems, it replaces heavy gravel drainage layers, drastically reducing structural load while efficiently managing water runoff and preventing root zone saturation. Its high compressive strength resists long-term loading, ensuring consistent performance.
