Removable Natural Turf System
StrathAyr Natural Turf modules enable stadiums to host a wide range of natural turf and hard surface events. The natural turf modules are located either in the stadium or an outside nursery.
Large & Strong
The system consists of 2.4m by 2.4m (8ft by 8ft) galvanised metal modules. The modules incorporate the proven StrathAyr System rootzone, incorporating ReFlex® mesh elements, to maximise grass growth and durability in a shallower, lightweight rootzone.
The turf modules are easily exchanged to overcome excessive wear and the effects of extended time in the shade. For hard surface events the entire field can be removed to an outside nursery.
The modules are moved with forklifts and generally installed on a concrete base. Air and heating channels are incorporated within the module design.
The StrathAyr Natural Turf Modules are proven under the precise requirements of Davis Cup tennis finals, American Football and soccer.

A modular tennis court is owned and maintained by Australian tennis’ governing body to enable ties to be held on grass at various venues around the country. Tennis requires a perfect grass surface, with heavy clay profile and grass cut to 4-5 mm.
The court was used in the Davis Cup tie between Australia and USA in March 2016 in Melbourne. It was transported 1,800 kilometres/1,100 miles for the event and installed three weeks before match practice to provide an excellent playing surface. Footage can be viewed at www.daviscup.tv/video-archive.
A previous version of the court was used for three seasons of Davis Cup finals between 2001 and 2005 in Melbourne and Sydney. That also yielded first-class results and elicited favourable comments.
NRG Stadium, Houston, Texas
NRG (previously Reliant) Stadium is a retractable roof, multi-use venue. It hosts NFL, international and major league soccer, college football, rodeos, rock concerts, monster trucks, Disney on Ice, circus, basketball, presentation dinners and numerous other events.
The StrathAyr system was installed in 2002 as the stadium required a flexible surface and frequent use at a reasonable cost.
The 1,250 modules that constitute the turf surface and perimeter area have been removed more than 20 times a year for a variety of events. The modules are moved out in eight hours and reinstated in 10 hours. The modules at NRG were in use from 2002 to 2015 and are now undergoing refurbishment.
Sam Houston Race Park, Texas
The system combines a natural turf racetrack with a roadway crossing for heavy vehicles. On race days the modules provide a perfect racing surface. On non race days the modules are removed to create a durable roadway. The StrathAyr system has been in use since 2008.
A modified design of the StrathAyr system makes a large part of this major flower show portable, with modules prepared in a nursery and trucked to the city centre display once mature.

it's STILL GROWING
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.
How ReFlex® Technology Works
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
