Tuffgrip is our established thin surfacing system and is produced in accordance with SHW Cl 942. It was jointly developed with BP for highways and other paved areas.

It uses high quality Polished Stone Value (PSV) aggregates and our approved specially-developed polymer modified binder.

Tuffgrip is tough on noise, skid resistance and on wet weather spray. It is also tough enough to stand up to heavy traffic yet provide an ultra-smooth ride. Tuffgrip is laid only by our Contracting division and comes with a five-year guarantee underwritten by the contractor (clause 942).

The mix design and choice of aggregate size provide a texture depth that is retained throughout the life of the surfacing, and gives significant reduction in noise over more traditional surfacings, such as Hot Rolled Asphalt and concrete. It is available in a range of aggregates and PSV. 


The main advantages of Tuffgrip when used as a maintenance treatment, either as inlay or overlay, or as a surface course for new construction, are:

  • Restores texture and offers skid resistance
  • Strong and durable
  • Excellent resistance to deformation
  • Enhanced ride quality
  • Reduced noise
  • Excellent spray reduction
  • Provided as a system- Hanson manage the approval process
