STABLEdrain

The application of STABLEdrain in the upper levels of the filter drain media provides a reinforced layer within the filter drain structure.  STABLEdrain distributes the loads imposed by vehicles and so can withstand both accidental overrunning and being traversed in an emergency, resulting in a dramatic reduction of both stone scatter and vehicle embedment, which can require clear-up and recovery operations respectively.

Carnell's STABLEdrain improves road safety and reduces the impact and cost of vehicle encroachment.

The patented technology was independently tested by TRL in December 2002 and successfully completed 78 individual tests, which involved the trafficking by a range of vehicles at various speeds.
