TERRAM drainage geocomposites provide an easy-to-install alternative to conventional granular drainage layers in building and construction projects.

Filter / net / filter composites are used for general area drainage and are easy-to-install, factory-assured replacements for stone installations.

Filter / net / membrane composites are used to drain from one side only and provide a barrier to the other – a cut-off drain.

Both types can be deployed vertically or horizontally.

The textile provides the filter function, allowing liquids and gases to pass into the net core while preventing soil particles from washing into and clogging the core. The net collects the liquids and gases which can then be conveyed to collection points. Membranes are used to provide the barrier function and prevent the passage of liquids and the majority of gases.

  • Drainage cores manufactured from HDPE nets which provide good flow under high loadings

  • Robust construction provides a long service life

  • Stable under load

  • Good chemical resistance

  • High volume flow paths for gases and liquids

  • Lightweight and easy to handle
