Leaning Pillars/Chimneys

Just like all foundations, chimneys are influenced by the performance of the ground supporting them. There is a distinct difference though between the average house wall and a chimney, the weight. The height and design of a chimney requires many more bricks in its construction and this contributes to greater weight. This heavy mass sits on a footing that occupies a relatively small area, making the chimney more susceptible to detrimental changes in the soil’s characteristics.

Typical mechanisms of chimney failure involve loss of support for the chimney footing. This can be driven by changes in the moisture levels within the soil, which alters the strength and volume of the soil upon which it sits. Problems arise when the movement is differential with one side of the chimney footing moving more than the other side, or moving relative to elements of the house to which it is attached. 

The change in support for the chimney can be compounded by the nature of the footing system. The foundation may be tied into or part of the existing house foundations or an independent element that can consist of a single component (concrete pad) or was manufactured from numerous pieces (stacked stone, brick corbel). The strength and integrity of the footing and inter-relationships with surrounding building elements will influence the problems that can manifest themselves when the ground support is compromised.

Foundations may settle unevenly through over-wetting or soil drying, causing the structure to tilt and lean. The degree of rotation being compounded by the height of the chimney, its connection to other parts of the building and the strength and cohesion of the foundation. Frequently chimneys will lean away from the building, pulling away from adjoining walls or causing interference. The results being large wall cracks on attached walls, distortion and protrusion of perimeter walls and deflection of surrounding floors. If movement is severe, the chimney itself may exhibit masonry distress, with cracks propagating through brickwork and noticeable rotation affecting the balance of the entire structure.

The team turned up on time and carried out the work efficiently. Although my cracked render didn't close up totally, I'm happy in the knowledge that the ground is underpinned. When I get the cracks repaired, they are unlikely to crack again. Thanks again, guys.

I cannot recommend this company enough, they were absolutely incredible! From my first meeting with Phil I felt assured that he knew exactly what he was talking about and he made the stressful situation we were going through so much easier. We then had Sam come out and he was fantastic and again put us at ease so it was a no drainer that we would be going with them. The team that came and completed the job were again so amazing, professional and friendly. They left the house so clean and made sure to inform me of what was happening every step of the way. Thank you to the Rectify team for an amazing experience from start to finish.

Rectify was really prompt with their service, did a great job explaining the details of the problem, the work involved, and the process to correct it. The resin injection process is very precise and can be targetted with great accuracy. The work itself didn't take long at all and the turn around time was great; having the work done about a week after agreeing to the quote. Highly recommend.
