Roadrain

Road Drain is a drainage geocomposite designed to protect roads, and is commonly known as an EDRC, or Roadside Drainage Screen.
Road Drain collects and channels laterally-migrating ground water which is captured over the entire face of the screen and runs into a perforated pipe incorporated into the solution, for subsequent discharge at an appropriate point.
It has an impermeable geospacer core that prevents any sideways migration of the water.
It provides an economical alternative to conventional solutions using aggregates and is a far simpler solution that is much faster to implement.
The geospacer’s void ratio (i.e. the proportion of voids in the material) is significantly higher than that for aggregate materials and the water flows much faster as a result. Road Drain has a much better flow capacity than 50 cm of stones.
