TERRAM drainage geocomposites are manufactured by laminating geotextiles, geonet cores and non-permable membranes to produce a composite product suitable for replacing traditional granular drainage systems.

Geosynthetic drainage systems, such as the collection and transportation of rainwater, groundwater or other fluids such as leachates and gases, are being increasingly used as a more effective and economic alternative to traditional granular based solutions.

In critical structural drainage applications such as basements, bridge abutments and retaining walls TERRAM geosynthetics are used extensively, replacing porous concrete blocks, no-fines concrete and other conventional materials.

Typical applications include:

• Landfill Caps
• Retaining Wall Drainage
• Basement Protection
• Highway Drainage
• Verge Toe and Batter Drains
• Bridge Abutments

Geocomposite drains offer a low weight, easy to handle, factory controlled, environmentally friendly alternative to \'traditional\' drainage methods such as low fines graded stone.

Geocomposite drains comprise of three key elements; a filter fabric, a free draining core and a filter fabric or impermeable membrane and are perfect for a number of applications including road and structural drainage, green roofs, Sustainable Drainage Systems (SuDS) and in the collection and venting of landfill leachate and gases.
