Arkil Ltd has developed a high friction material for anti-skid applications.
The product has been developed and tested under the guidelines for High Friction Surfacing (HFS) and is now in full production at its High Polished Stone Value (HPSV 72+) stone quarry in Lispole, Dingle, Co. Kerry.
The PSV of the stone is 72+ which makes it comparable to the market standard calcined bauxite which is also 72+. Arkil Ltd has focused in on this rare stone quality and is marketing this new product as an alternative for HFS.
The advantages of Calcined Bauxite:
- Lower Carbon Footprint: As it is a natural source, its production energy costs are much lower and not therefore market price index is not as volatile to energy markets
- Price Competitiveness: Due to lower production costs as it’s produced from a natural rock source
- Arkil Ltd is strategically located to supply UK/US and European markets also much lower carbon footprint in production and transport.
Typical Applications:
- Approaches to Roundabouts
- Junctions
- Traffic Lights
- Pedestrian Crossings
- Cycle Lanes

Our high friction material & how it works
HFS stands for High Friction Surfacing. Also known as anti-skid surfaces, these are pavement surface treatment systems that are composed of “tough” polish-resistant, abrasion-resistant aggregates bonded to the pavement surface using a resin. Although both “hot applied” and “cold applied” HFS processes have been used throughout the world. Cold applied HFS are the most commonly used in the U.S.
High friction surfaces are used primarily for restoring or enhancing the skid resistance of a pavement surface, but can also be used for lane delineation, bike paths, traffic calming or for decorative purposes.
HFS Technical Specification
Our high friction surfacing has been tested for all the regular stone properties such as polished stone values, aggregate abrasion value, Los Angeles etc. and has also been subjected to the Wehner Schulze method of testing for skid resistant values of road surfacing in the Transportation Road Laboratory in France where it has performed very favourably with the competition.
High Friction Surface (HFS) Facts
- HFS enables the skid resistance on existing pavements to be restored
- In instances where friction demand is highest, HFS is an ideal solution for “spot treatment” of a pavement
- In comparison to replacement or removal of existing pavements, HFS is an effective, low cost treatment
- HFS installation can be achieved in short timeframes (4 – 6 hours)
- HFS adds minimal thickness (1/8″ – 1/4″) – which is an advantage in circumstances where overhead clearance is limited
- Installation can be applied to a wide variety of pavement types
- HFS can be coloured in order to enhance delineation
Uses And Applications
Our high friction surfacing can be used in various locations such as dangerous bends, pedestrian crossings, approaching roundabouts, school areas, high stress areas, slip roads to motorways, steep inclines and junctions.
