Missouri
Foundation Repair Design and Oversight
Engineer-designed foundation repairs: pier layouts, underpinning and wall bracing, with inspection and a final letter.
What the work involves
After diagnosing a problem, an engineer can design the repair: number and spacing of piers, underpinning, wall anchors or bracing, and drainage changes. The design lets you get comparable bids and is often required for permits. The engineer may inspect during installation and issue a completion letter, which helps at resale.
