Road shoulder drainage provides an alternative to the conventional solution using a ditch filled with aggregate and protected by geotextile whose purpose is to filter water. The rainwater falling on the road surface is drained away by culverts. This also involves draining the groundwater from the roadside Rainwater from embankments can also flow into the road shoulders. The need to drain embankments has become as pressing as that for draining the carriageway itself.
Our Roadrain and Stabidrain geocomposite road shoulder screens used for road and motorway drainage are extremely effective at speeding up road shoulder drainage.
