What Sinking Floors and Concrete Slabs Indicate
The presence of sinking floors and uneven floors is something that many people are not aware of. Occupying a property for an extended period of time may result in progressive changes being so slight that they are not detected, yet newcomers to the building may notice a slope straight away. Tell tale signs can be the pet toys always accumulating along one wall of the room or your eggs always slide to the back of the fry pan.
Fortunately in instances where the construction has suspended timber floors, most floor sagging can be corrected by adjusting the supporting stumps or piers. However, where there are masonry walls, either internally or around the perimeter, the continuous strip footing will need to be corrected. In the case of concrete slabs, this would also be addressed by treating the foundation elements together with the panels, across the entire affected area.
Not all floor settlement represents foundation movement. Infill slabs are a flooring system that is independent of the perimeter walls and so are capable of moving in isolation. Therefore the mechanism of failure may be unrelated to external factors that typically influence perimeter foundations. Commonly, deterioration of the underlying ground below the slab, due to poor preparation or plumbing failures, leads to unacceptable level variations. As with structural slabs, treatment involves supporting the portion of the slab that is out of tolerance and requires correction.
Our Results Speak, See How We Rectify
Every project is assessed on its individual merits, with treatment tailored to the mechanism of movement, whether that is suspended timber floors, masonry strip footings, or independent infill slabs. Below is a look at real before and after outcomes from our residential slab and floor levelling work.

What Are the Leading Causes of Sinking Concrete?
Explore the leading causes of sinking concrete slabs, from soil shrinkage and tree root invasion to poor drainage and construction impacts, safeguarding residential stability.
Soil Shrinkage and Swelling
Changes in moisture levels, especially in clay-rich soils, cause ground to swell when wet and shrink when dry, leading to uneven foundation support and subsidence.
Tree Root Intrusion
Trees and large shrubs absorb significant water from the soil, causing shrinkage beneath foundations. Roots growing under houses physically move soil, destabilising foundations.
Water Erosion and Leaks
Persistent water leaks from broken pipes or poor drainage wash away or soften soil under foundations, leading to subsidence as the ground loses bearing capacity.
Excessive Weight Load
Adding extensions or conservatories without proper ground assessment can exceed the soil’s bearing capacity, causing the foundation to sink. This is a common issue when expanding residential properties.
Construction and Excavation Nearby
Excavation and construction work adjacent to properties disturb soil stability. Vibrations from heavy machinery and removal of adjacent support significantly impact foundations.
Leaks from Plumbing
Leaking pipes, especially under houses, erode or soften soil foundations over time. Unnoticed leaks frequently cause subsidence by changing soil consistency and bearing capacity.
