Composite drainage products

Terram drainage composites are designed for a wide range of applications where drainage is required.

The composite consists of an extruded drainage net or cuspate which is heat bonded to either a geotextile on both sides or geotextile with a geomembrane. This type of construction provides both filtration and drainage properties in a single flexible sheet.

The extruded net products provide very high flow rates under pressure and are suited to high performance applications such as landfill cell leachate drainage, tunnel drainage and buried structures subject to lateral pressure.
