Another source of information is to call large stadiums. Most all have a concrete base and when they have "horse events" (rodeos, horse shows) they bring in base/footing. Your concrete will act as your "base layer." Top will be your "footing." Your "loose footing" is normally determined be your discipline. Dressage riders like 2," Hunter jumpers like 3-4," while your western performance riders will want 6."
Just remember, You never cut into your base. So be careful who you let "run your tractor!" Indoor's are easier than outdoor arenas. Base is so important in your outdoor arenas.
Figure your costs. You might be able to bust up the concrete, compact it, and let it stay as your base, and reduce the amount of "dirt" loads for your top layer. You will be amazed at the cost of "dirt!" Good luck! |
