A major cause of cracked walls is the ground beneath the foundations which is in a constant state of change, what kind of change largely depends on soil type.
In granular, sandy soil, there will be some degree of erosion as the sand particles can be washed out. Clay soil, on the other hand, will swell with increased moisture content and shrink as it dries, forming “voids”. Such soils can reach saturation, turning into something of a “bog” with little load bearing capacity.
Other causes resulting in cracked walls include, water services, sewer, storm water services, poor drainage, and damage from vegetation.
Wall Crack Repair
By injecting our resins, compromised soils will be consolidated and stabilised.
Our approach involves injecting our product into the ground to both increase the load bearing capacity of the soils and raise the subsiding part of the building as conditions allow. A pre-assessment to determine key injection points is imperative.

Frequently asked questions
Will the wall cracks be eliminated?
Our first priority is to minimise further movement of the structure by consolidating and improving the load-bearing capacity of the ground. To confirm that this has been achieved, we only need a 1-3mm lift. Once this has been done, we then aim to return the structure as close as possible to its original levels as conditions allow. We cannot guarantee closure to cracks in walls, even though cracks may be minimised through our treatment. Cosmetic work should not be attempted straight after our treatment, due to the structure needing to settle.
How long will it take to complete the job?
Most residential jobs are finished within a few hours. Bigger projects may take over a day; your project manager will discuss the time frame as part of the free site assessment and quoting.
When can I carry out cosmetic repairs?
Wall cracks are the consequence of subsidence, after the injection process the building needs time to settle back into its original shape. You should therefore always wait for a few weeks after a lift before carrying out any cosmetic repairs.
Do I need to vacate the building whilst work is carried out?
Your Project Manager will discuss this potential need with you during the free site inspection and quoting. Sinking floor piers and other circumstances might necessitate your removing furniture and fittings so that we can work inside. But in most cases, there is no need for you to vacate the property, however it is preferable to have the work area cleared prior to our arrival.
Do you have to park on my property?
Our crew will arrive in a self contained truck, when planning road access, our work truck is approximately 8.0m long, 2.5m wide and 3.2m tall. Due to our long hoses we can work up to 70 metres from our self-contained mobile unit, so there should be no need to park any heavy vehicle in a sensitive area.
What are the guarantees of your product?
Drawing on over 60 years’ combined experience, Resinject only use an Australian Standard resin and inject to a depth of up to 3.5 metres if necessary. We also provide plenty of support around each lift point. This is why we can confidently guarantee our product against significant settlement for a full 50 years.
