Although I am not an owner of high dollar riding arena footing, I like to think I treat other people’s facilities as mine.
So, in the event that I were to own one of these facilities, I have been curious about the geotechnical design of riding arena footing and the care and maintenance of these surfaces.
While I respect the rules of whatever facility I am at, as an engineer, I do not understand any technical reasoning for some of the restrictions. The footing starts with the prepared sub-base, to which is added 4"-6" of base on which 2"-4" or footing is added.
I don’t see how lunging or a horse doing a “free school” during winter, would incur any different “damage” than the wear and tear of that footing that happens by use of that surface in a jumping course.
Below is a Penn State Ag Extension write-up on this subject.
