I am in the process of planning a new shop to go in a new to us home. The original plan had been to make it with concrete floors so future owners could convert it into more garage space easily if they wanted but the house we ended up putting under contract won’t support a driveway into the back yard just a 4’ walkway so the decision of which is better has come back up and I’m curious what others think.
Some of the Pros and Cons of both from what I can see.
Wood floors are easier on the back and feet. My last couple garage shops have had concrete floors and even with mats after 4-6 hours my back is pretty sore. I took a one week class at The Woodwright’s School and while I was tired at the end of the day even after 8 hours of standing on the wood floors I wasn’t as sore as my time on the concrete floors. I thought about putting sleepers with a wood floor over the top on concrete but that really adds to the price of the shop since your paying for concrete floors as well as wood floors and you likely would have to tear it all out if you sell the space as a garage.
Concrete floor would be at grade making moving tools and materials in and out of the shop easier. While this is true I wonder just how big of a deal long term this really is. If you have a shop that is 2-3 steps up or has a ramp moving lumber into and projects out of it wouldn’t be to hard even in my case where I’m going to need to use a cart to wheel it from the shop out to the driveway. Tools might be problematic but once they are in your shop how often really do you need to get them out so it seems like more of a one time deal that can be solved with some strong backs and maybe something like a engine hoist.
Floor load concerns with wood floors. This is one I am struggling with a bit. Taking a Grizzly 15” planner as a example and using weight / footprint I can see needing to space the wood floor joists around 200 pounds per square foot and this isn’t the largest tool possible one could buy. If I went wood joist floor what would a good number be for planning purposes? I would like to keep the floor as low to grade as possible so was thinking 2X6 or 2X8’s spaced 12” on center with support every 5’ but am having a hard time finding load tables on the Internet with that high of numbers. I will likely consult a Structure Engineer to help with designing the floor after we close on the house anyways but I would like to know ahead of time what I should aim for and if I’m possibly just over thinking this problem or if concrete floors much higher load capabilities is worth being harder on the back?
Heat/Cooling of the space. I was planning on putting hard foam insulation under the concrete floor to thermally break it from the ground and hopefully keep it from getting damp as well but wasn’t sure how well that would work. It seems like wooden floors with insulation would work better but I have never had a well insulated space either way so am not sure.
Power and dust collection under the floor. I don’t know if the design I have in my mind currently will let me run dust collection under the entire floor but it should let me extend dust collection and power into the center part of the floor easily enough. I have always had to step over these things in my shops or send it overhead and deal with the occasional interference so it would be really nice to have that under the floor. While I know I could run those under a concrete floor it does seem like a pain to me. You have to worry about drainage of the trench and how it’s covered not to mention what future buyers might think of it which does seem like a hassle. Not unsolvable just less than ideal in my mind.
Cost? I have no idea how to compare the cost of these two solutions at this point. I guess once I get into the house and can talk to some contractors I can compare them a bit better but right now I can only guess. The only thing I am thinking is that while I can do most of the wood floor construction myself as it’s basely a free standing deck I would probably hire out the entire concrete part of the job to someone with the skills and equipment to do it.
Anything else I am not thinking about?
I appreciate any and all feedback,
