We did this job in Springfield, Virginia. Replaced old carport driveway and front entryway as it was a very bad shape (more than 45 years old). We use the 4000 PSI concrete with wire and fiber for more support. We dug down in the carport and installed footers so the new carport would not fail.
We put rebar rubber for 2 foot on center in the carport. We installed control joints as needed. We put expansion in front of the carport and also in front of the apron. We also did a light broom finish. Turned out beautiful!
