Bowing or Bulging Walls – Who Should I Call?
A wall that appears to bow, bulge or lean out of line can be caused by several different forms of movement. Because the underlying cause is not always obvious, significant distortion is something that should be properly assessed rather than simply covered over or repaired cosmetically.
Ask About Your Wall ProblemWhat Does a Bowing or Bulging Wall Look Like?
A wall may appear curved, pushed outward, uneven or no longer vertical. In some cases the distortion is obvious from a distance; in others it becomes noticeable because brickwork, stonework or internal finishes have moved out of alignment.
The movement may affect an entire wall or be concentrated around a particular area. Cracking can sometimes appear alongside the distortion, but a wall can also move without producing a dramatic visible crack.
The important issue is establishing why the wall has moved and whether the movement is stable before deciding how it should be repaired.
Why Can Walls Bow or Bulge?
Loss of Restraint
Walls rely on appropriate connections and restraint within the building. Problems with ties, fixings or structural connections can sometimes allow masonry to move away from its intended position.
Wall Tie Problems
In some cavity-wall properties, deteriorated or defective wall ties may be associated with cracking, movement or distortion and can require specialist investigation.
Roof or Floor Movement
Parts of the building that connect to an external wall can influence how that wall behaves. Movement or inadequate restraint at roof or floor level can sometimes contribute to outward movement.
Ground or Foundation Movement
Movement lower down within the structure may affect the wall above. Cracking, distortion or other signs elsewhere in the property may be present at the same time.
Moisture & Material Deterioration
Long-term moisture, corrosion, weathering and deterioration of building materials can affect how walls and their connections perform.
Older or Traditional Construction
Stone, solid-wall and traditionally constructed buildings can behave differently from modern masonry and may require someone familiar with the construction type.
Wall Distortion Deserves Proper Attention
Not every uneven wall represents immediate structural danger, especially in older buildings where some historic irregularity may have existed for many years.
The concern increases where the movement is new, appears to be progressing or is accompanied by other changes to the building.
Who Should Look at a Bowing or Bulging Wall?
Structural Engineer
Where significant movement or stability is in question, a structural engineer can assess the wall and wider structure and advise what further investigation or repair may be appropriate.
Building Surveyor
A surveyor can be useful where the wall problem forms part of a wider building defect or where you want a broader assessment of the property's condition.
Structural Repair Specialist
Once the problem is understood, specialist contractors may carry out restraint, reinforcement, wall-tie replacement or other specified structural repairs.
Can a Bowing Wall Be Repaired?
In many cases there are repair methods available, but the correct solution depends entirely on the cause and construction of the wall.
Possible work can range from local masonry repairs to specialist restraint or reinforcement systems. In more serious situations, larger sections of masonry may need reconstruction.
That is why diagnosing the problem before choosing a repair method is so important.
Repointing, plastering or filling cracks may improve the appearance without dealing with movement behind the visible surface.
