Earlier, strong winds used to cause overhead irrigation heads to break, which led to the ground being watered unevenly. We also got complaints about the footing from customers who rent stalls. I was also always aware of how the wind was blowing and constantly checking to see if the footing was moist enough.

Before Capillary Flow was installed here at IDA, I experienced that the tracks could be too wet if they had just been watered. In the afternoon, the tracks got dusty, hard and even slippery. During the day, it was very difficult to find the perfect moment to ride, when the surface was ideal for my horses.

Before the CapillaryFlow system was installed, it was very important to the farm owner to not install an irrigation system that was heavily computer based because that kind of system easily breaks in thunderstorms, and we get a lot of them in Wellington.

In our other ring, the surface is uneven and has a lot of dry spots because of the top watering. It is hard to keep the surface evenly moist throughout the arena and it’s hard for the horses to ride in that ring.

The Capillary Material ensures a level foundation

The durability of the Capillary Material ensures the groundwork of equestrian arenas doesn’t deteriorate over time. The porosity of the Capillary Material lets fluids sift through but particles won’t migrate into subsequent layers, or eventually into the drainage and irrigation systems at all.

Capillary Material ensures a level foundation

Have pristine sands and lush grass in any weather condition

Capillary Hydroponics grass arenas

The Capillary Hydroponics system grows healthy grass with deeper roots in sand, giving horses and riders just the right cushioning, impact firmness, responsiveness and grip for a safer, more comfortable experience.

Adjustable sand footing

With sub-surface moisture control, one can do away with sand additives like fibers and synthetics making it possible to change swiftly between discipline criteria and ensure optimal footing conditions all the time.

CapillaryFlow Sand Arenas

No sitting water

Total drainage control

The proprietary Capillary Material allows grass to be grown in sand instead of an open medium, making drainage capabilities significantly superior when compared to soil grown grass. This also means, there's no sitting water or slush to deal with even after the heaviest precipitation.


The sub-surface irrigation ensures your arena is perfectly hydrated ensuring both rider and horse aren’t inhaling harmful dust while riding. For your grass the moisture control system provides water to the roots, making them grow stronger for a year round riding experience. All, with significantly less water consumption.


Our system is specifically designed to grow grass that can withstand high traffic and harsh weather conditions, making it an excellent choice for equestrian arenas with busy schedules.

How CapillaryFlow helps keep the perfect sand moisture zone
Perfect moisture level

Regulate moisture levels in any condition

Regardless of top layer, season and geography the surface will always have the moisture level of your choice through subsurface irrigation.

Stronger grass
Subsurface heating
No leakage of fertilizers and pesticides
Moisture & Irrigation
85% reduction in water consumption

Decreased water consumption

Independent studies indicate the Capillary Hydroponics has 85% less water consumption than traditional overhead irrigation. By both collecting rain water and irrigating from below there is less surface water, reducing evaporation which in total is decreasing water loss and consumption. By not using overhead irrigation moisture level is also held consistent with your preferred profile for your sand and grass.

Automated maintenance

Fertilizers and pesticides are distributed through the water in circulation, allowing for lower total consumption and an automated distribution. The moisture levels of sand and turfgrass can be monitored and set virtually for a hassle-free workflow.

No leakage of fertilizers and pesticides with CapillaryFlow

No leaching into the environment

Using an enclosed system with natural sand and underground basins, it filters all water naturally from air and water pollution and then collects it to be reused. By using subsurface irrigation and distribution of fertilizers and pesticides in the water there is no leaching of harmful substances or microplastics into adjacent soil, surrounding water streams or ground water.

No fibers or sand additives in CapillaryFlow equestrian sand

Healthier footing

Doing away with additives, dust control products and other substances helps to improve the horses’ health. Subsurface irrigation creates the perfect moisture levels which is better for the joints of horses. In addition, the Capillary Wash Box allows for the washing and renewal of equestrian sand to make it like new.

By far the biggest advantage of riding on the Capillary Flow arena now is that I never have to worry about the surface not being even or too wet. I can be confident that my horses are always getting the best conditions to perform at their best and that they will last.

Dr Ricardo Gutierez

The horses under my care that have been ridden during this past year on the CapillaryFlow system footing has been a very positive one. The consistency (no dry spots or wet spots) of the footing throughout the day has greatly reduced the necessity of intervention on my part on the horses articulations. In general I have found the Capillary system to be of great benefit in keeping the horses healthy and supple during their training routines.
