I didn't see a great area to ask a question like this so I will ask in this area. What is a good depth for concrete for a basement floor?
any help is appreciated
The usual for slab-type floors us 3 1/2" to 4". Much less and the concrete will be a lot more prone to developing cracks.
Ditto what he said
A sure way to verify is to contact your local building department. What we say is just the code in our areas.
