It won't fix itself

What is subsidence, and why does it matter?

Subsidence occurs when the ground beneath your home becomes unstable and can no longer support the structure evenly. Over time, this causes parts of the house to settle lower than others, leading to cracks, uneven floors, sticking doors and a range of other issues.

At Foundation Solutions, we specialise in stabilising homes affected by subsidence using screw pile underpinning, a proven method for halting movement and re-levelling homes affected by unstable ground.

House affected by subsidence

What causes house subsidence?

It's usually about what's happening in the soil beneath your slab.

Reactive clay soil cracking
Reactive clay soils

Soils with high clay content expand when wet and shrink when dry. These changes can lead to constant movement in the ground, which stresses and destabilises your foundation over time.

Water leak under a slab
Poor drainage or water leaks

Broken pipes, poor stormwater management or surface water runoff can wash away or soften soil under your foundation, causing parts of it to sink.

Large tree near a home
Tree roots drawing moisture

Large trees near your home may extract significant moisture from the soil, especially during dry periods. This shrinkage can lead to foundation settlement.

Inadequate site preparation
Inadequate site preparation or fill

Homes built on poorly compacted fill or with inadequate footing support can start to move within just a few years of construction, especially under load.

Stop movement before it worsens

Our solution to subsidence is engineered and proven

House subsidence won't resolve itself, and cosmetic fixes won't last if the ground is still moving. Repair methods like resin injection may only have a temporary effect if the root causes are not addressed. Here's how we tackle it:

  1. Begin with a Home Check-up to assess signs of subsidence, such as cracking, uneven floors, and sticking doors or windows.
  2. If needed, we provide a forensic structural engineering report to confirm the cause and recommend the right solution.
  3. We then design and install screw pile underpinning, targeting the unstable zones to stabilise and, if required, lift your foundation.
  4. Once the home is stabilised, you can move forward with confidence, knowing your structure is secure and future movement is no longer a risk.

If you suspect your home may be affected by subsidence, early action is key. The sooner it's diagnosed, the more options, and better outcomes, you'll have.
