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.

The Geocomposite must:
  • Be robust to survive installation and service life
  • Be stable under load to resist deformation

  • Chemical resistance

The Geotextile filter must:
  • Possess an apparent pore size to suit the soil and prevent the ingress of fines
  • Provide sustained performance without blocking

KTTL Geocomposite drains are proven to satisfy these criteria and stand the test of time. The product have established an impressive track record in building and construction projects across the globe.

KTTL Geo-Composite Drain Benefits:
  • High-volume flow paths for liquids and gases
  • Light weight and easy to handle
  • Quick and easy to install
  • Cost-effective replacement for primary natural resources
  • Reduced environmental impact by avoiding the use of natural occurring minerals
KTTL Geo-Composite Drain Applications:
  • Highways: vertical edge-of-carriageway drains intercept the lateral flow of ground water.
  • Retaining walls and bridge abutments: to reduce pore water pressure and avold backfill saturation.
  • Engineered landfills: with the additional requirement of long-term chemical resistance and high compressive strength.
  • Tunnels: ground-water-seepage interception between rock face and the tunnel lining.
  • Buried structures: vertical and horizontal drains for basements, culverts, car parks, reservoirs.
  • Roof gardens: Green roof systems require lightweight components capable of high In-plane water flow.
