You can seal the cement or you can maybe put a flooring down. I was going to do tile flooring with a drain. I think there are a lot of ways you can do it.I have space as well but what do you put on the floor and how do you clean it?? My barn has cement, so I cannot put the wood shavings directly on the cement. I was thinking about layers of styrofoam and then wood shavings on the top.. but again, cleaning?
