New Const. 2 garages: 26′ x 26′ & 17′ x 56′, need advice
I have read many posts on concrete garages. I understand that wire mesh is a waste of time. I know that I need expansion joint material all the way around the perimiters. It has been advised to put 6mill plastic down as a vapor barrier. I plan on drilling into the surrounding foundation cement 5/8″ holes, 5″ deep and epoxy in 4 foot long #4 rebar every 2 feet. I then will connect across in both directions #4 rebar to make 2′ x 2′ grid and hold them up from the 7 inch base (one garage has gravel and the other has small chip rock) with bricks to make the rebar imbeded in the middle of the cement.
How does this sound. I am having a professional sub do the work, but want to know what I need to have him do to get the best garage floors.
Too much? Over kill? Too little? Am I missing anything? How thick cement? 5″? 6″? Any guidance from those in the know would be appreciated.
