The planning and design for the roadways, drives and shared spaces of a development of new build homes at Barns Green in West Sussex for Berkeley Homes, incorporated permeable concrete blocks and resin bound to create a mixture of aesthetically pleasing and varied paved surfaces. The two permeable systems worked integrally alongside each other, reducing the need and cost of conventional piped drainage which in turn enhanced the landscape design of the housing estate creating a natural rural look for its village location.
Groundworks company Martin Joyce, contractors on site worked with Clearstone for the resin bound areas. Clearstone’s specifications, gave detailed instructions for the sub-base required for a resin bound surface that is fully SuDs and NPPF compliant for sustainable drainage.
Resin bound surfacing provides a water-permeable surface when laid on an open grade binder asphalt, the mixture has open voids across the surface, allowing air to flow freely and the rainwater falling onto it to filter straight into the ground making it an ideal permeable system for this site which had existing mature trees and newly planted woodland areas
