I would like to know if there are any impact tools that I need to make the subfloor permanent or stable to avoid sound later. I don't want to use DRIcore for this matter.
I helped finish a basement 2 years ago with what I thought was the best carpeted floor I have walked on.
You can lay carpet or engineered hardwood on this. Provides a thermal break, a way for water to escape, and is virtually noise free. Some people will say you don need the tapcon screws. You do. I have personally seen a short period of moisture make 3/4" plywood curl up in a basement after it has been down for years.
