We installed a new arena (110’ X 200’) a few months ago and are having trouble with the sand that was installed. Our horses are sliding all over the place. Here is what we had installed:
- 4 inches of top soil was removed and the underlying clay was compacted and laser graded.
- A textile fabric was put down over the clay.
- 3 inches of m89 was put down as our base. It was compacted and laser graded.
- 4 inches of quarried sand (NOT manufactured sand, dark red in color, angular in shape) was put down and laser graded.
The problem: We are a private hunter jumper barn and our horses are going straight through the sand to the m89 base as they are trotting/cantering/jumping. Turns are even worse, as the horses’ hind legs literally slide out from under them. We are unsure how to fix it, especially since we blew our budget on the original install. We have considered removing two inches of the sand and replacing it with m10 to add stability to the shearing motion, but aren’t sure it would make it stable enough. We have also considered adding the geo-textile sand additives. Does anyone have any experience with this problem or any other options that we could consider?
