High Friction Surfacing (HFS) is a specialist road surface treatment that significantly increases skid resistance and reduces braking distances on high-risk road sections. The treatment works by creating thousands of tiny contact points (micro-texture) between the road surface and vehicle tyres, delivering exceptional grip in both wet and dry conditions.

Grantex supplies precision-screened and dried angular aggregates no larger than 5mm, with the range including calcined bauxites, granite and copper slag, specifically engineered for HFS applications. These materials are combined with specialist binders to create durable, high-performance anti-skid surfaces on bends, junctions, pedestrian crossings and other critical areas.

Anti-skid surfacing aggregates, including our calcined bauxites and granite, create a highly textured micro-surface that significantly improves tyre grip. This skid resistant surface enhances grip, reduces braking distances, particularly in wet conditions, helping to prevent collisions on high-risk road sections such as sharp bends, busy junctions and pedestrian crossings.

The angular shape and controlled particle size of our HFS aggregates deliver the exceptional skid resistance that makes these critical areas safer.

As a proud associate member of the Road Safety Marking Association, we work closely with highway authorities and companies, ensuring our supply is high-quality and high-performing for highways and anti-skid applications.

Grantex aggregates are also carefully sourced, screened and dried using our state-of-the-art facilities. We also conduct our own laboratory testing to ensure the quality and suitability of our aggregates for their intended application.
