I'm working on the plans to finish my basement and am leaning toward the 1" foam with 3/4 OSB or Plywood over top option.

The pool table is about 1000 pounds.

What do you think? am i going to have a crushed floor?

Also- i live in Chicago and wanted to insulate the floor, otherwise i would probably not do a subfloor.

Thanks for any advice.

If you used blue foam and Advantec subflooring I see no reason it would not work.

Thanks. Any idea what a 4x8 sheet goes for? Doesn't look like they show pricing online.

I have a 1200 sq ft basment and dont want to break the back.

And yes, 1" blue board under.

No clue, last time I bought it, it was lower then CDX.
Make sure it's T X G.

and i would just tapcon that to the floor right?

1000lb pool table divided by 4 legs is 250 lbs per leg. The feet on most pool tables usually spreads out a bit to spread the load. So in reality, it is not much different than a 250lb person standing there.

When I did it I used 1/2 blue foam and 3" long Tap Cons. Floor does not move at all and the screws grabed great.
Unless you can find screws longer then 3" I'm not sure if they would hold with that thick a foam.
The 1/2" was enough to give me a theramal break and it really made the floor warmer.

How thick was your top layer? Did you use advantec?

ryanmcl,

One other factor to consider is the floor joists spacing. Is your floor joist spaced at 16" or 24" O/C?

There is some science in physics behind the answer to your question and concern.

It's a basement. No joists involved.

Looks like im going to move forward with 1" xps and 3/4" adventec T&G. Thanks for the assist.
