“Surface water drainage from developed areas is increasingly affecting our river catchments. As development intensifies, so more water runs rapidly into rivers and less filters through the soil. This sealing of the ground can and does lead to localised flooding and water pollution, and will only get worse as our climate changes. We need a new approach to drainage that keeps water on site longer, prevents pollution and allows storage and use of the water”

“Sustainable Drainage Systems” The Environment Agency Advice Note

Our resin-bound macadam allows surface water to pass directly through it into the ground, surfacing or storage systems beneath. We are currently developing construction techniques which will combine our porous surfacing with a geo-grid or other ground strengthening technologies to provide a high performance SUDS.

We have recently completed trials of a SUDS system in conjunction with BASF chemicals at their eco trial house at Nottingham University. We are monitoring the system’s performance and are continuing with further trials.
