“But if prepared correctly, it will indeed absorb shock.”
OK. Tell me more! Oh, or was that covered in the clay base & screenings from one of your above posts? That makes it sound like your footing is a pea gravel/screening mix.
Am I correct in that assumption?[/QUOTE]
It’s not a gravel/screenings mix. There’s a lot more to it than slapping down some clay, putting screenings on top, and then shoveling the gravel on top. Like any good base, the layers should not mix.
The problem with the pea gravel packing down into the clay, described by another poster, will be fixed by putting the screenings on top of the clay (screenings are flat, so they pack down to form a more uniform layer than gravel). This let’s the screenings pack, not the gravel so that there will be a solid base for the pea gravel to sit on top of. Doing this makes sure it won’t pack down, and get hard or uneven. With a solid, uniform base in place, you can add enough of the pea gravel on top so that it’s soft enough to absorb shock, but not so soft that it’ll bog the horses down.
It’s the same as you would pack down the base for a sand arena (in this area at least) so the sand doesn’t just get ground down into the underlying sand/clay (depending if you’re 5 feet this way or that down here).
As an aside, we’ve had 14 vettings done this year, and every one of the vets first went “What?!”, and then loved it. The most important thing to do with this type of arena is make sure that you’ve got the base, depths, etc all correct before starting.
