This material consists of either bi-planar or tri-planar high-density polyethylene (HDPE) geonet having non-woven polypropylene (PP) geotextile heat bonded on both sides.
As a seepage interceptor, the material functions ideally under high loading conditions for directional channeling of drainage behind MSE retaining walls and sub-surface drainage for steep slopes and embankments. This solution is also used to control water seepage between a rock surface and tunnel linings.
Industrial and environmental applications for TerraFlow™ include landfill cell and capping, liner cushioning protection, and for protecting geomembranes with effective drainage of mitigating gas and liquids for leachate ponds, brine ponds and wastewater ponds.
