Drainage/reinforcement geocomposites

Backfills for geosynthetic reinforced walls should be free draining,because unexpected failure of these structures can be caused by lack of control of groundwater or seepage. An appropriate geocomposite can therefore be incorporated horizontally and/or vertically to provide adequate drainage.

Moreover, the development of geocomposites made of a non woven geotextile and a woven geogrid will allow increasing multifunctional use of geotextiles, affording reinforcement, drainage, and filtration capacity.
