TECHDRAIN Drainage

Mines

Located over the containment liner in caps and closures, drainage geocomposites are used to avoid hydraulic pressure buildup in topsoils Leachate collection layer: Geocomposite drains offer the most reliable system to avoid the accumulation of leachate over the base liner while keeping its structure unsaturated Leak detection layer: Geonet and geocomposite drains are placed in between containment layers to create a void space through which leaking fluids can be detected and displaced outwards Formed by a triplanar HDPE geonet thermally bonded over one or both sides to nonwoven PP geotextiles
