Hardwood floor in basement on concrete – new house
I’m building a house in CT and I have a question for the forum.
In (under) my basement, I have virgin dirt, 12” of stone, 2-3” of spray foam insulation, then 4” of concrete slab. I am looking to put down ¾” hardwood flooring, and have been given different pieces of advice on what to do.
I was told that I could put down another vapor barrier (6 mil plastic) and then ¾” plywood nailed to the slab, and then the hardwood on top.
I’m worried that if I put the poly on top of the concrete, then I will create a moisture trap around the concrete.
What would you do?
Thanks in advance for the help.
