I've been doing my research on this and can't seem to find what I'm looking for. If anyone is knowledgable about this or could point me in the right direction it would be greatly appreciated.
I've come across an indoor ring that has had concrete poured in it for alternate use. Now we're going to try to turn it back into a riding ring..... How much filler would be required to make it safe for the horses to be ridden in there occasionlly?
Thanks so much!
