Sinking Family Home Releveled with Precision Lift

The Brief

The owner of this three-bedroom home in ACT, purchased in 2015, began noticing troubling signs of structural movement. The corner of their house, which had recently been cosmetically patched and remortared, suddenly developed significant cracks. Inside, the ceiling and corner cornices in the same area showed signs of movement, with gaps and cracks appearing. Concerned by the rapid deterioration, the homeowner contacted Buildfix to investigate the cause and provide a lasting solution.

Their priority was to stabilise the foundation, lift the affected area back into place, and prevent further damage to ensure the safety and longevity of their family home.

The Challenge

Our assessment revealed that the home was suffering from severe foundation subsidence in one corner, caused by reactive clay soils beneath the property. Over time, the clay had dried and shrunk, destabilising the foundation and creating a chain reaction of structural issues.

Externally, the recently patched brickwork had reopened, with significant cracks forming at the corner of the house. Internally, the stress from the subsidence was evident in cracked cornices and gaps in the ceiling, highlighting the seriousness of the issue.

The challenge was to stabilise the reactive clay foundation and lift the sinking corner back to its original level without causing additional strain on the surrounding structure. This required precision and expertise to restore stability and protect the home’s integrity for the long term.

Our Solution

After a detailed site analysis, we implemented our DeepLift injection technique to stabilise the foundation and lift the affected corner. This advanced method allowed us to target the underlying cause—unstable reactive clay soils—while providing a minimally invasive repair.

We drilled to a depth of 2.2 metres at key points around the subsiding corner and inserted aluminium pipes. Through these pipes, we injected GeoPoly™, a specialised resin designed to stabilise and strengthen the foundation. The resin expanded deep within the foundation soils, filling voids and compacting the reactive clay to create a solid base.

As the resin expanded, our technicians carefully monitored the process in real time using a precision laser system. This ensured that the foundation was lifted evenly and with millimetre accuracy, restoring the corner to its original level by 10mm.

The Outcome

The results were transformative. The foundation was stabilised, halting further movement, and the sinking corner was lifted back to level, closing the external and internal cracks. The ceiling and cornices inside were restored to alignment, eliminating visible signs of stress.

The homeowner was overjoyed with the outcome, expressing relief at seeing their family home stabilised so quickly and effectively. “It’s incredible how quickly Buildfix fixed what I thought would take months of rebuilding,” they said.

By addressing the root cause of the problem—reactive clay soils—Buildfix provided a permanent solution. The home now stands safe, stable, and secure, giving the homeowner confidence and peace of mind for years to come.
