Understanding Cracked Walls: Subsidence Causes and Factors
The issue of subsidence, especially in the context of cracked walls, stems from a multitude of causes and contributing factors. All of these share a common thread—a shift in the ground, resulting in soil movement.
Moreover, the impact varies depending on the type of ground involved. When the ground undergoes changes, building subsidence becomes a prevalent concern.
In such cases, foundations or footings lose their full support and begin to sink due to the weakened ground.
Moisture levels in the soil affect reactive clays as they expand and contract.
Oversaturated clays lose their strength resulting in footing subsidence. In loosely packed soils, such as sand and silt, the fine particales in the soil can wash away causing the footing to settle.
Neighbouring trees and shrubs absorb water using their roots causing movement in the soil as it soaks up moisture in the ground.
Poor foundation design or inadequate compaction of soil during construction results in movement of the structure as it settles.
Burst or cracked water pipes including blocked sewage and rain gutters can oversaturate clay soils or wash fine particles from sand and silt soils and cause footings to subside.
Extreme or Seasonal Weather
Natural disasters such as flooding, drought and earthquakes affect soil moisture levels in particular clay resulting in excessive foundation movement.
Renovation or Construction
Vibration caused by nearby construction activity such as drilling or piling, or heavy road traffic causes soil particles to shift and settle, resulting in ground subsidence.
Types of cracks
Often found on masonry walls, they appear like steps in the brickwork / blocks and typically follow mortar lines. The mortar and masonry deteriorates due to the movement of the affected wall.
Found running horizontally between bricks and in some instances, they transition to become a step crack. Internally they typically appear as gaps between skirting board and floor or between the cornice and ceiling.
Usually visible in building extensions where two walls join and in modern buildings at the sides of large window and door openings. The gap is often wide at the top of the joint, exposing the lining.
Expansion Joint Crack
When footings subside, gaps can open at door and windows.
Start measuring wall cracks from the convenience of your home.
If you notice wall cracks around your home that are:
Large cracks that start at windows, doorways or corners of buildings
Cracks wider than 5mm
Jagged, horizontal or vertical, zig-zagged, stepped in brickwork or follow mortar line
These characteristics may indicate weakness in your property’s foundation.

How do you know if a wall crack is serious?
To determine the seriousness of a wall crack, look for the following signs that may indicate a significant problem with the structural integrity of your home, potentially necessitating extensive foundation repair work, including underpinning and rebuilding:
- Width: Any crack wider than 25mm is a strong indicator of a serious issue.
- Shape: Cracks that are wider at the top than the bottom, or those visible from the external walls, can suggest subsidence.
These are crucial indicators that should prompt you to seek professional advice and assessment from Mainmark Solutions for a comprehensive evaluation and potential solutions.

- Cracks measuring less than 5 millimeters in width are typically confined to the plaster and can be easily repaired and concealed.
