Royal Warrant

Setting the winning standard in equine surfaces


An additive proven to improve the stability and structure of a sand arena, CLOPF Fibre allows the horse to work ‘on top’, rather than ‘into’ the surface, allowing freedom of movement and reducing strain and risk of injury.

At Martin Collins Enterprises Ltd, we are pleased to confirm that we do NOT use waste carpet in CLOPF, only virgin material is used and sourced. This ensures the product does not have contaminants that may come from using post-consumer material. The fibres used have been Laboratory analysed for Persistent Organic Pollutants (POPs) which are chemical substances that may pose a risk to health and the environment, and we are pleased to confirm that the levels contained within our CLOPF are well below the concentration limits stated in the Government guidance.
CLOPF is the optimum surface enhancer for private, professional and competition arenas.

The Environmental Agency in the UK, recently (Spring 2021) confirmed they are withdrawing the automatic allowance for the use of shredded waste carpet in equestrian surfaces (LRWP43). If you are looking for a clean, safe fibre then CLOPF should be your choice. 

As the ultimate performance fibre, CLOPF will completely transform deep, dry and dusty surfaces, improving consistency, adding energy return and enhancing the stability underfoot.

By adding CLOPF Fibre to an existing sand surface, you create more ‘root structure’. This allows the horse to work on top of the surface, rather than into it – for an even, balanced and confident riding experience.

  • Add to existing sand surface
  • Excellent moisture retaining qualities
  • Can be used both indoor and outdoor
  • Secure footing
  • Even surface for better performance

CLOPF Fibre reduces tracking and surface displacement, and improves energy return and stability, reducing the risk of concussion and injury from working on a poor and uneven surface. This not only helps to enhance performance, but can help to increase the lifespan of your arena too.

It’s important to keep a sand and fibre surface moist at all times, for optimum performance – either through rainfall or watering. However, the moisture retaining qualities of CLOPF Fibre may reduce the amount of watering needed in long spells of dry weather. 



  • Pau Racecourse France

    The addition of CLOPF® by Martin Collins Ltd to the existing fibre-sand surface at Pau racecourse, in view of a renovation, has given entire satisfaction. The works were completed within the agreed deadline, and the reduction in kickback (the principal original problem), is significant.

    The indoor arena is admired by all, especially the surface, which makes us the envy of the District!
