How thick will the mason pour the concrete in the sidewalk and driveway?
Must local building codes call for 4″ of 3,000 to 3,500 psi concrete in sidewalks or pedestrian walks. This of course, must go on top of a tamped earth. Two inches of ¾” crushed stone as our base. Tamp tight and pour four inches . In the driveway, we also tamp the earth first, and then install four to six inches of crushed stone. Tamp stone tight to earth and install 9 gauge steel wire flats on three lifts. Pour six inches of 3500 psi concrete.
