Fireplace chimneys made of rock or brick are usually pretty heavy. Large footings were typically poured to help distribute this weight, adding MORE weight to an already heavy structure. Because of this, chimneys often settle more quickly than the houses they are connected to causing a lot of distress. On the Emerson Chimney project, VersaGrade underpinned the chimney with Helical Piles. The chimney had settled several inches, and was pulling away from the house, taking the hearth with it. After re-leveling, the distress disappeared!
