ReitenRight is an impressive additive that was designed to bring life to your indoor or outdoor arena. Its high quality materials, natural rubber and an interlocking textile web provide great rigidity and a durable, long-lasting outcome. ReitenRight itself will not freeze which helps to prevent your sand from freezing in the winter months. Olympian and early ReitenRight ambassador, Leslie Reid, has found that ReitenRight works really well as an additive for her sand paddocks. Given its porous nature, ReitenRight binds well with your sand, preventing it from blowing away in strong winds. It does very well after a winter of heavy snowfall and while you can expect a small amount of material to run off after heavy rains, it holds up much better than any other type of additive material.
