This is commonly seen with concrete slab floors and concrete driveways.
In this situation, sub soils have been compromised either due to water washouts, reactive clay soils, and damage from surrounding vegetation. Symptoms that may be noticed include, pumping slabs and unlevel concrete slabs. Slumped concrete slabs can often be seen in residential homes and factory floors.
How to Repair Sunken Concrete
We inject our resin under the slabs, void filling the affected area, and increasing the load bearing capacity of the soils which is supporting the affected slab.
Part of the re-levelling process is re-supporting adjoining areas that could have been compromised due to the subsidence. Additionally, piers could also be installed in certain situations.

Frequently asked questions
What do I have to do before your crew arrives?
In order for us to carry out the works, it is ideal for you to have all your services located. Please ensure that you have this on hand when we arrive. i.e., water, gas, sewers, storm water drains, phone lines, TV cables and irrigation piping
How long does it take for the resin to cure?
Our resins cure in minutes; once the injection is completed, there will no further chemical reaction taking place. For example, Driveways and factory floors can be used immediately after the clean up.
How urgent is it to address a compromised foundation?
Leaving an unstable structure can cause further issues. By having an early assessment/treatment, will save further costs and lessen further damage occuring.
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.
What is the alternative to resin injection?
Traditional underpinning can be carried out as an alternate method. However, this generally requires a lot more time on site, bigger equipment, with more disruptions and ultimately more expensive.
What noise and dust is to be expected?
Our generator has been enclosed in a custom-designed cabinet to minimise noise levels, so it is relatively quiet. Drilling may be noisy, but this is completed quickly, and when drilling indoors, we capture the dust with vacuum cleaners and small amounts of water.
