Sloping floors? Your foundation might be to blame

Uneven or sloping floors are often a sign of subsidence or structural movement beneath your home.

Sloping floors aren't just a quirk

A floor that feels uneven or noticeably slopes in one direction isn't something to ignore. While minor variations in older homes can be harmless, significant or worsening slope is often caused by structural movement, typically foundation settlement or subsidence.

At Foundation Solutions, we specialise in identifying and fixing the underlying causes of sloping floors. With our structural assessment process and screw pile underpinning solution, we help restore your home to level, and your peace of mind.

Measuring floor levels in a home with sloping floors

What causes floors to slope?

Structural movement is the most common culprit. Here's why it happens.

Crack in cement foundation with tape measure
Uneven foundation settlement

When fill that has been placed settles over time, it contributes to subsidence within the structure.

Subsidence from poor soil conditions
Subsidence from poor soil conditions

Expansive or unstable soils can change volume with moisture levels, gradually undermining parts of your foundation. This differential movement puts pressure on your slab and causes it to tilt.

Plumbing leak under a slab
Plumbing leaks or stormwater issues

Water escaping under or around your slab can erode or soften the supporting soil, contributing to settlement and sloping.

Cracking from poor construction
Poor construction or inadequate soil compaction

In some homes, sloping floors appear within years of construction due to poorly compacted fill or substandard foundation preparation. These flaws reveal themselves slowly over time.

Restoring level starts with stabilising your foundation

How we fix sloping floors at the source

Floor levelling compounds or re-tiling won't solve the problem if the ground beneath your home is still moving. Nor will polyurethane or resin-like injection material, which can't be seen as a guaranteed fix if the root cause of poor soil conditions is not addressed. Our screw pile underpinning process focuses on permanent structural repair, installing typically below the influence of these factors:

  1. We begin with a non-invasive Home Check-up to assess the severity of the visual defects.
  2. If movement is present, we offer a forensic site inspection report to formally diagnose the issue, with floor levels, which is a must.
  3. Our screw pile underpinning system is then designed and installed to stabilise the foundation and re-level the affected areas with controlled hydraulic lifting.
  4. Once stable, we can advise on cosmetic rectification options that won't need to be redone.

If your floor feels like it's sinking or sloping, let's find out why, and fix it for good.
