Our concrete block basement wall 11 feet long was bulging out right in the middle with cracked mortar lines up to 3/8ths of an inch running back to the upper and lower corners of the wall. Also, the wall cracked vertically straight down the walls right through the blocks about 4-5″ from the adjoining walls. Area Waterproofing inspected and gave us 2 options. We chose to have them buttress the inside of the wall with 6 vertical beams anchored in the floor and ceiling joists. Guaranteed 20 years not to move. Friendly crew. Worked quickly, cleaned up and did a professional job. In and out in about 3 hours. Would highly recommend for any similar work.
