Situation
After noticing significant cracks and gaps appearing throughout their home, the owners of a single-storey, concrete slab-on-ground brick veneer house in Bray Park reached out through our website enquiry form. A site visit confirmed what they feared: their home was suffering from major foundation movement. Our team explained the underpinning process and the importance of an independent engineering assessment, a step the resin provider they had previously consulted had bypassed.
The partnered engineer's inspection revealed extensive signs of structural distress: vertical and horizontal stepped cracks in the brick veneer, cracks in internal gyprock and ceiling cladding, and gaps over 10mm wide around window frames and isolation joints. The report clearly outlined the need for underpinning to stabilise the home and prevent further damage.
Solution
The engineering assessment showed that foundation movement exceeded the thresholds in Table 4.1 of AS2870-2011, with a differential movement of -142mm. To address this, Foundation Solutions installed 24 external underpins around the affected perimeter of the home, reaching depths of approximately 5.5 metres to ensure stable founding conditions.
Our team worked systematically to complete the underpinning with minimal disruption. Clear communication, careful site management and attention to detail were all key to delivering a solution that stabilised the structure and reinstated the homeowners' confidence in their property.
Outcome
The final levels achieved were outstanding, with a remarkable 110mm lift that restored the home to within serviceable tolerances. The homeowners were thrilled with both the technical outcome and the experience of working with our crew. This project is a perfect example of the difference expert underpinning and an honest, engineered approach can make.
"We are so stoked with the results. Both the boys gave 100% every day, and I couldn't believe how clean and tidy they kept the work area. I would 100% recommend them to any friends or family that might need work in the future."
