A Sign Of Subsidence
What does un-level buildings mean?
The appearance of internal or external wall cracks, inability to open and close windows and doors, cracked floors and more can all signal an un-level building.
Once a building becomes unlevel, it is crucial to fix it immediately or risk further damage and potential hazards. This requires foundation repair, footing repairs, and house re-levelling.
Using resin injection ground stabilisation, we improve ground compaction. We can then raise and re-level sunken buildings, adding strength to the ground to support the foundation.
We have successfully raised, re-levelled, and re-supported thousands of homes worldwide.

Foundation Repair For Un-level Buildings
Before & After Treatment
Houses that need to be re-levelled often develop cracks in walls, sinking floors, sticking windows or jammed doors.
These houses require their foundations to be re-levelled.
Mainmark’s non-invasive and cost-effective solutions can raise, re-level and re-support your home. Our innovative methods minimise site disruption and completed within one day.

What causes un-level homes and buildings?
There are many different causes of subsidence and various contributing factors.
All involve some change in the ground, which, in turn, generates movement of the soil.
As well, different types of ground are more affected by different conditions.
When ground has been affected, building subsidence is common. Foundations or footings are no longer fully supported, sinking due to weak ground.
Soil Types
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.
Tree Roots
Neighbouring trees and shrubs absorb water using their roots causing movement in the soil as it soaks up moisture in the ground.
Footing Systems
Poor foundation design or inadequate compaction of soil during construction results in movement of the structure as it settles.
Excess Water
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.
