Generally chimneys are built on a separate foundation from the structure they accompany. These heavy structures are placed on a smaller foundation causing the weight to be distributed less evenly over the soil which can accelerate foundation settlement. Leaning chimneys become less stable the more the lean and are subject to collapse during periods of high wind due to their compromised structure.
CNT Foundations can install a helical pier system that will transfer the weight of the chimney deeper into the earth to providing the necessary support.
- Gap developing between the house and chimney, usually larger at the top than the bottom
- A noticeable lean or bow in the chimney
