Duralayer Multi ® / Duralayer Multi ®+

Duralayer Multi® is a close textured, single layer application which is suited to a variety of asphalt surfacing applications where a low textured and deformation resistant one layer treatment is required.

It was designed following a request from a Local Authority for a cost-effective,  single layer solution. It utilises locally-sourced aggregates and for a variety of applications including major roads, rural roads, housing estates, car, caravan parks and trench reinstatements. Duralayer Multi® can be used for a variety of applications. The material has a low surface texture and low air voids, which results in material that doesn’t segregate like traditional materials, therefore protecting lower layers from water ingress. 

Duralayer Multi® is available in 20mm, 14mm, 10mm and 6mm sizes and is laid using conventional paving equipment in line with BS 594987.
