Porous Asphalt
W N Surfacing can install Porous Asphalt Surfaces. These asphalts allow liquids to pass through them, removing the problem of surface water making them a great option for surfacing areas which have specific local planning requirements to ensure Sustainable Urban Drainage Systems (SUDS). The surface course is supplied in either a 6mm or 10mm finish and this laid upon a porous Binder Course and Subbase Material as per the specification.
