Rubber makes for a great cushion and can add that extra bounce you’re looking for in your arena while helping prevent injury to your horse as well.
Wax and Polymer
Wax and Polymer coatings are usually preferred for indoor arenas, but it is a perfect solution for any arena wanting to manage dust or water. The coating will act as a dust-control agent by weighing down the sand particles and keep it from rising into the air. With coatings, you’ll not only have a dust-free arena that you’ll never have to water again, but it’s like riding on a cloud!
