One of our dojos in our federation put down 1 X 3 boards on edge as a frame that would support a 4 X 8 X 3/4" plywood sheet, attaching the plywood to the boards with screws. Then he put another layer of 4 X 8 X 3/4" plywood at right angles to the first layer, attaching it with nails. It's coated with several layers of polyurethane finish to protect the plywood and the feet. All of this was done over a concrete substrate with vinyl tiles on the concrete. It has the advantage of being easier to disassemble if he decides to relocate the dojo.
