KTTL - Geo Composite Drains

KTTL Geo-composite drains are manufactured by bonding together PP geotextiles, & high density polyethylene HDPE membranes Geonet by heat laminating, whose geometry create channels with a high flow capacity, also under pressure and at very low gradients and also create easier-to-install replacements for conventional granular layers. The PP geotextile provides the filter function so this allows liquids and gases to pass into the net core but prevents soil particles from washing into and clogging the core. The net collects the liquids and gases which can then be conveyed to collection points. The HDPE Membranes are used to provide the barrier function and prevent the passage of liquids and the majority of gases.
