Building floor with standard "code" joists. On cement piers. Subfloor is standard 7/8" OSB.

My plan is to have a rubber gym type floor rolls. 3/4" black rubber roll material.

Would you do between the OSB and rubber?

Seal it?

PAtch the gaps with HVAC tape

PAtch gaps with waterproof roofing sheets and HVAC tape

Use a product I haven't even thought of that is perfect for what I am describing?

Expansion foam?

Be kind. I am a newb. Just want a decent old man shop to piddle, build guitars, cutting boards and woodworking projects in between.

Seems like you’d have a hard time moving machinery and such over rubber matting.

LVT? Easy to put down, can take a beating, water resistant, affordable?

I would lay a moisture barrier, thick plastic sheeting over the ground the building is being built on. Moisture will absorb into the wood eventually and rot the plywood out if not.

Personally, I'd go with 3/4 inch tongue and groove treated plywood for the subfloor. That way they lock together and no need sealing the seams.

How high will the piers be off the ground until you reach floor level. Like mentioned, if real low, do some thick plastic over the ground for moisture abatement. It won't cost much for the peace of mind.

Also like already mentioned. Cushioned floors will be comfortable on the feet if you find yourself standing doing shop work, but moving big tools around if on rollers will not be much fun because wherever they sit for a while, they will settle into the rubber.

Get those foam gym mats that have puzzle price edges, relatively inexpensive and you can move them or toss them when you spill glue all over it

Colossal waste of my fricking time and money.

3/4 Advantech OSB Sub flooring. Tongue and groove. I used this on my house 10' off the ground. Good stuff!

We’re back before the floor again. Roof leaks in more spots that I have buckets.

Wait, you have multiple roof leaks and you're concerned about what type floor to install? Or am I missing something here????

One thing I do know----you build from the foundation up and renovate from the roof down. No point putting work in an older building if the roof is going to leak all over it.

No. This is a new construction. Floor is obtained but not installed. Waited til we finally had a good soaking rain. The ONLY somewhat smart thing I did. Fortunately I had moved everything to one side. By sheer luck it’s the dry side.

So no. While flooring is obtainEd it’s on the back burner now until the roof is a roof. Last night if I owned a maul I’d have beat the whole thing down. Right now I am so disgusted I’m giving myself a day or so to calm down and figure out what I even want.

I keep seeing this as a sure thing, but my grandparents house is raised, almost 70 years old, no moisture barrier, and original floors. I dont think its as big a concern as its made out to be if its open to airflow and not ice cold inside.

How heavy are your woodworking saws, drill presses, lathes, or are you just going to whittle?
