Viaflow

Viaflow is a porous asphalt available for use in Base, Binder Course and Surface Course pavement layers. It may be used as part of a designed SUDS (Sustainable Urban Drainage System) which are designed to dissipate surface water through the material to a suitable drainage system. Viaflow is most commonly used in conjunction with a free draining sub-base, and carefully selected geotextiles,geogrids and/or geomembranes
