Guides and explainers
Plain-English, engineering-grounded answers on concrete cancer, house subsidence and underpinning. Start with the signs, understand the causes, then compare methods and costs before you talk to anyone.
Understand the problem
A practical way to read a crack in your wall, based on width, direction and behaviour, so you know whether it is harmless or worth an engineer's opinion.
The specific warning signs that a house is subsiding or its footings are moving, and what each one is telling you about the ground below.
Why Australian homes move, from reactive clay soils that swell and shrink with moisture to thirsty trees, leaking pipes and poorly compacted fill.
Concrete cancer is corrosion of the steel reinforcement inside concrete. Here is the mechanism, the causes, and where it shows up in Australian buildings.
How concrete cancer is properly repaired, from removing failed concrete and treating the steel to patching, protecting and preventing it coming back.
The main ways a footing is strengthened or re-supported in Australia, how each method works, and the situations each one suits.
Where Australian home insurance typically does and does not pay for structural movement and concrete repair, and how to read your policy before you assume you are covered.
Plan the repair
Realistic Australian price ranges for underpinning and concrete cancer repair in 2025, what drives the cost, and why quotes vary so widely.
The checks worth doing before you hire, from licensing and engineering to how a quote should be written, so you back the right contractor for a structural job.
From the first crack you notice through engineer's report, quotes, the works themselves and monitoring afterwards, so you know what a proper job looks like.
