Geocomposite drainage systems are specifically developed to replace costly, conventional open grade aggregate and perforated-pipe subsurface drainage systems. This drainage System is created by laminating a filtration geotextile on one or both sides of a Geonet. Geocomposite Drainage Systems have acquired acceptance as state-of-the-practice because they feature sufficient in-place drainage and offer reduced material cost, installation time and design complexity over conventional systems.
The basic principle behind Geocomposite materials is to mix the best features of different materials in such a way that specific applications are required in the best possible manner and at reduced cost. In this way, the benefit/cost ratio is optimized. These geo composites will normally be geo synthetic materials, but not forever. In some situations it may be more beneficial to use a non-synthetic material with a geo synthetic one for best performance and/or least cost. As seen in the following, the number of possibilities is great — the only limits being one's ingenuity and imagination.
When a geotextile is applied on one or both sides of a geonet, the separation and filtration functions are always gratified, but the Geocomposite drainage function is immensely improved in comparison to geotextiles by themselves. Such geo composites are usually used in intercepting and conveying leachate in landfill liner and cover systems and for conducting vapor or water beneath pond liners of different types. These drainage geocomposites also make improved drains to intercept water in a capillary zone where frost heave or salt migration is an issue. In all cases, the liquid enters through the geotextile and then travels horizontally within the geonet to a suitable exit.
