Description: RoaDrain Roadway Drainage System provides a synthetic subsurface drainage layer that outperforms open-graded base layers. The RoaDrain System features durable, nonwoven geotextile filters laminated to top and bottom of a tri-planar geonet core. These components offer distince benefits: while the geonet core provides a viod-maintaining structure with high compressive strength to resist deformation, the geotextile material offers superior separation and filtration of fines and other materials. 

Uses:  The RoaDrain System can be specified for any application exposed to excessive moisture including highways, airports, railroad trackbeds, embankments, and detention ponds. 

Advantages: Installed directly beneath a Portal Cement Concrete pavement surface to remove water rapidly. Beneath PCC joints and joint repairs. Beneath the aggregate base course to shorten the drainage path. Above the subgrade to act as a capillary break over frost-susceptible soils, helping to eliminate frost-heave.
