What are the standards for control joints in concrete???
(OP)
I was wondering what the industry standards are for vertical and horizontal concrete? We believe we may be way overdoing our control joints at 8' for 4" flat concrete and every 12' for 6" concrete. Also, we have lost a job because of our reccommended thickness for a basement foundation wall. We recommended a 12" thick 9' tall wall for a 66' span. Did we overcompensate with concrete thickness? What would you have reccomended?

Also, make your joint pattern as nearly square as practicable and with no more than a 1.2 to 1 ratio of length to width.
