Our new barn (or recycled barn) is nearly finished! It used to be an RV shed built on a concrete pad where a mobile home used to be placed. So it has good drainage all around, a good roof, etc. we just had to enclose it and build the interior walls and stalls. But I do not like the concrete floors, especially since both my horses are pawers and will tear their hooves apart on the concrete in no time. I thought about stall mats but they are very expensive. But we have at our disposal a large amount of long 3 X 12's- they look like they came from an old dock or something. They are very heavy and would easily stand up to a horse, so I am thinking of using them for flooring over the concrete. I think they will be easier on the horse's legs and feet, and warmer in winter. We are planning to install them before building the walls, so they will not need any kind of nails or fasteners to hold them down and will not shift or move around. Is this a good or bad idea? Anyone here have wood floors, and what are the pros and cons?
