Foundations too shallow
Shallow foundations can turn into a structural risk once movement, frost exposure or added load starts to matter. Foundation depth issues in your area are best assessed before a repair route is chosen.
The earlier this is assessed, the easier it is to protect programme certainty and avoid repeat callouts or rework. When you are ready to discuss delivery, start with the Foundation Depth Issues service overview.

What causes this issue
Foundations may be too shallow because the original build did not account for frost depth, soil conditions, nearby trees or later changes to the structure. Older extensions and altered buildings are especially vulnerable.
Situations where this applies
This is typically needed when recurring symptoms, project risk, or compliance concerns mean a patch repair is no longer a reliable option.
Quick checks you can try
Record crack patterns, any seasonal movement, and whether nearby trees or frost exposure are present.
Signs this issue is becoming serious
Escalate quickly when movement is progressing, doors or floors are changing level, or the foundation depth is visibly below expected support.
How this gets resolved
We review the structure and ground conditions with an engineer, then deliver underpinning, piling or local remedial work to the agreed design so the foundation reaches the required depth.
What affects cost and complexity
Cost and complexity usually depend on access, scale of remedial work, existing condition, and whether supporting works are needed to complete the fix safely.
When to call a groundworks specialist
Call when an inspection flags shallow founding, when cracking suggests inadequate depth, or before loading the structure further.
