Q. Hi there! I wonder if its possible to put in a polished concrete floor on a first floor above a double brick structure? Do concrete floors have to be on the ground floor only due to their weight or can you have one on a first floor? Thanks
A. You can have a concrete floor on the first, second or third floor if the sub-floor will support the weight.
Concrete weighs 25 lbs per sq. ft. at 2 inches thick. Check with a structure engineer for an analysis of your project. They could tell you what, if anything, needs to be done before you can pour a concrete floor on your 1st floor.
