ParaDrain® geogrids (Figure 1 and Figure 2) are planar structures consisting of a biaxial array of composite geosynthetic strips. The strips comprise of a core of high tenacity polyester tendons encased in a polyethylene sheath. The longitudinal strips have a channel profile, which has a geotextile filter strip laminated to it. This forms an open channel for the drainage of water contained within soils.
ParaDrain® is a unique and new generation of geogrid, combining reinforcement and drainage functions in one product. ParaDrain® can be used in embankment and slope reinforcement where the combined reinforcement and drainage functions can operate effectively in marginal fills.
