StrathAyr Track System

  • The StrathAyr Track

    The StrathAyr Track provides an extremely resilient, safe and long lasting natural grass surface. The racetrack construction consists of a specially engineered profile that incorporates a base drainage layer of gravel and pipes, a lower layer of sand and an upper rootzone layer reinforced with unique ReFlex® mesh elements.

    The result is a natural turf racing surface which combines remarkable surface strength, excellent drainage and improved grass growth, allowing increased usage over a longer period.

    The Hong Kong Jockey Club pioneered this all weather natural turf track concept 20 years ago and since that time StrathAyr has further refined the design and developed specialised construction machinery.

    Cost-Effective Racing Turf

    The StrathAyr Track race track construction is significantly more cost-effective than other natural turf construction options due to the unlimited life of the track profile, lower maintenance costs, no cancellations and greater usage.

    More Racing

    The ability to handle all types of weather conditions, combined with high load bearing capabilities, better wear resistance and faster recovery after damage provides racecourse managers with the opportunity to host more races and increase their returns.

    Safer Racing Turf

    The technology provides greater surface uniformity and the action of the ReFlex® mesh elements provides a cushioning effect on impact, lowering the potential for injury. Throughout 20 years of racing there has never been a fast rating on any of the ReFlex® tracks.

    All Weather

    There has never been a wet weather cancellation on a StrathAyr Track or sportsfield. The drainage capability for each project is designed to suit local climatic conditions.


    Precision installation of the system is facilitated by a number of machines, purpose-designed by StrathAyr.

    Prevents Compaction

    The unique application of ReFlex® mesh elements provides the load bearing capability of a secondary bitumen road which enables horses, trucks and turf equipment to travel over the surface in all weather conditions without compaction.

    Longer Life

    The compaction resistance provided by the inclusion of ReFlex® mesh elements provides a greatly extended life of the rootzone profile.

    Profile Design

    The StrathAyr Track design remains consistent across all countries. Only the drainage design and turf species selection will vary according to the climate.

    Track Management

    This hi-tech track is easier to manage than conventional profiles. Moonee Valley records show the StrathAyr Track requires less irrigation and has a lower maintenance cost than conventional racing turf  profiles.

    The StrathAyr Track is available world-wide.

  • StrathAyr Track Installations

    StrathAyr Track installations include:

    Darley's Osborne Park Training Complex, Australia

    A StrathAyr Track was installed at Darley's Osborne Park Training Complex, Agnes Banks, NSW in 2010.

    Tote Racing Centre, Australia

    A StrathAyr Track was installed at the Tote Racing Centre Launceston, Tasmania in 2008. This regional track hosts day and night racing.

    Kranji Racetrack, Singapore

    The StrathAyr Track at Kranji has been providing safe, all weather racing since 1999. The StrathAyr technology was selected following extensive trials comparing various drainage and growing medium concepts.

    Singapore’s StrathAyr Track now boasts a heavy racing program. Despite rainfall prior to and during meetings frequently exceeding 100mm (4 inches) and on occasions exceeding 200mm (8 inches) there has never been a race cancellation.

    Moonee Valley Racetrack, Australia

    The Moonee Valley Racing Club conducted its first meeting on the StrathAyr Track in 1995. The StrathAyr technology was selected following extensive trials comparing various growing medium concepts.

    Happy Valley Racetrack & Sha Tin Racetrack, Hong Kong

    The Hong Kong Jockey Club pioneered the all weather natural turf track concept in 1988 when the Happy Valley Racetrack was reconstructed. The Sha Tin track reconstruction of 1990 also incorporated mesh elements. The Hong Kong Jockey Club tracks continue to provide an intensive schedule of safe, all-weather racing.


    The StrathAyr System has also been used in numerous stadia including Reliant Stadium, Houston and 7 National Rugby League Stadiums in Australia.

  • Understanding ReFlex Technology

    ReFlex® mesh elements add an extra dimension to the performance of StrathAyr surfaces.


    When ReFlex® mesh elements - 50mm by 100mm (2" by 4") pieces of flexible polypropylene mesh – are blended uniformly within a rootzone profile the mesh elements reinforce three dimensionally, acting like thousands of springs to improve load bearing ability and resistance to compaction.

    The spring back action also creates a cushioning effect on impact, "bounce back" after impact. Improved rootzone aeration is achieved resulting in greatly improved grass growth and recovery after wear.

    ReFlex® performance benefits have been scientifically demonstrated and proven in some of the world's leading sports stadia and racetracks over the past 20 years.
    No alternative product can match the engineering performance of ReFlex®. In fact, some alternative rootzone reinforcement products have the opposite effect and actually increase the likelihood of compaction and poor turf growth.

    Understanding ReFlex® Technology

    • Soil particles interlock with the mesh, packing into the mesh apertures to form a soil/mesh cluster. These clusters then interlock to form a stable composite rootzone matrix.
    • When this matrix rootzone is compressed by players, horses or vehicles the mesh elements provide a dual effect. They act like thousands of springs, flexing vertically as the load is applied to the surface and returning to their original form after the load is released.
    • At the same time the applied load compresses the soil within the mesh apertures causing them to expand laterally. As the load is removed the apertures shrink back elastically and the surface profile recovers. This combined mesh flexing and elastic straining of the apertures provides unique impact absorption and surface recovery properties.
    • Equally importantly it creates and maintains voids along the length of the mesh filaments, which maintain air spaces in the rootzone, enhance capillary water retention and ultimately provide an improved environment for grass growth.
    • The load bearing properties provide a significant increase in surface strength and a built in resistance to compaction - leading to a greatly extended working life
