Question

Pressure Treated Lumber for Basement?


Is pressure treated lumber really needed for a bottom plate? I'm wanting to create a curved wall which I will do the top/bottom plates out of 3/4" plywood. Not sure if Home Depot/Rona has 3/4" Pressure treated Plywood?

Can I just use standard 3/4" plywood?
If not, what would work for this curved wall?

I do believe, that HD carries Pressure Treated 3/4" plywood. If not, a lumber supply company should have it.

Another option: use adjustable steel track.

Good option.

Yes, it has to be treated lumber. You can get ACQ treated plywood, but you'll have to go to a lumberyard. I don't think most box stores have it.

My house is only a year old and the builders installed the framing and insulation around the perimeter. They used 2x3 and no pressure treated bottom plate. Should I rip down everything around the exterior and install a pressure treated piece or is using that sill gasket foam (white thin stuff) under the bottom plate and over the concrete going to be fine?

If you can isolate the untreated lumber from the concrete, you'll be ok. Foam sillsealer like you described should work well, provided you can get it in there.
