Drainage Geocomposites
TERRAPRO™ TERRAM Drainage Geocomposites create easy-to-install replacements for conventional granular layers. For over 40 years they have established an impressive track record in building and construction projects worldwide, standing the test of time with high-quality performance.
The filter/net/filter composites are used for general area drainage and are easy-to-install, factory-assured replacements for stone installations. The 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.
