Priorities - Indoor Arenas:
Prority 1: make this a Long-Lasting facility - by using the correct type of sand, in the correct blend of particulate sizes
P2: provide superior "cushion" against concussive injuries to the horses - to prolong the career of the performance horse
P3: provide the correct traction + flexibility ("bounce") - to provide the "perfect competition conditions" suitable for an FEI-approved riding arena
P4: provide a low-maintenance surface that will retain the desirable sand conditions - such as level of sand compaction without "deadening the sand," moisture retention, etc.
