Geocomposites

Conventional granular layer drains can be replaced by higher performing, easier to install, geocomposite alternatives.
TERRAM geocomposite drains are created by bonding together textiles, membranes and nets in different combinations to suit a specific application, each layer providing a specific performance or function.
The textile layer provides the filter function, allowing liquids and gases to pass into the net core but preventing soil particles from washing into and clogging the core.
The membrane layers are used to provide the barrier function and prevent the passage of liquids and the majority of gases.
