Hydro-Keep Arena Hydrator

Hydro-Keep Arena Hydrator

Hydro-Keep Water Retention Additive

Premier Hydro-Keep is a safe, non-toxic chemical crystal that can reduce your arena watering by 50%! The crystal expands when wet, absorbing and retaining water. Over time as the soil dries, the crystal contracts, gradually releasing water and hydrating the surrounding area. As an added benefit, this continuous expansion and contraction reduces soil compaction.


Hydro-Keep Details

  • Retains water in your arena
  • Reduce watering intervals
  • Helps reduce dust
  • Used indoors and outdoors
  • Lasts up to three years
  • Non-toxic and safe for horses

Research shows that Hydro-Keep super absorbent polymers can release up to 95% of the water absorbed, making it available for your surface. One pound of Hydro-Keep can absorb 40 gallons of tap water and 31 gallons of rain water. With an essentially neutral pH, Hydro-Keep will break down into nitrogen, carbon dioxide and water with no residual toxicity. Hydro-Keep can be added to any of our other additives for enhanced moisture retention.

“My dressage arena gets used constantly – and for everything, not just dressage. We jump, play and ride in there with several horses every day. I used to have to water it twice a day and even then it was dusty after a couple of hours with the dry Colorado air. Since mixing in Hydro-Keep, I water it every 3 – 4 days. That is just amazing to me. It is economical to use and it’s saving me a lot in tractor/equipment use and valuable water supplies.”

How Arena Surfaces Affect Horse Biomechanics

Every stride is influenced by how the hoof interacts with the ground and the various qualities of the arena layers. An ideal horse arena footing surface allows horses to move efficiently, minimizes concussion, absorbs shock, provides support, and returns energy back to the horse.

*Please Note: Premier Equestrian can guide you to find a footing solution suitable for you and your budget. However, unless you are contracting our consulting services, choosing the correct sand and mixing the product is your responsibility. Results can and will vary depending on what material is available in your area. If you choose to perform your own installation, which many people do, Premier Equestrian can not be and is not responsible or liable for your installation.

Sand Note: All our footings are designed to be mixed with sand. There are, however, significant variations in sand in each area. Not all sands are appropriate to use as footing for your equestrian arena. There are many factors you should consider in determining the appropriate sand, including, without limitation, your riding style, the number of horses using the ring and the duration of such ring use, watering capability for the ring, the status of any current existing footing materials, seasonal weather conditions, and whether you ride on an indoor or outdoor horse arena. Combining Master’s Blend Footing with the correct type and depth of sand is required in order to build a safe arena surface. Please choose properly sized arena sand based on your proposed use. Feel free to call and discuss your arena questions with one of our representatives today!
