Generated explanation

The illustration presents perspective and cross-section views of a foundation repair using a new exterior sister wall alongside an existing foundation wall. The existing wall is shown bulging inward and developing a horizontal crack. The new outside wall bears on a footing extension next to the existing footing, with backfill and topsoil on its exterior side. The cross section calls for relocating the drainage tile beside the extended footing. Wall and floor framing remain above the existing foundation, and a concrete basement floor slab is shown on the interior.
