Frequently asked Questions

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.

Why does it take a licensed builder to carry site assessment?

Only a licenced builder has the knowledge and experience required to assess how a building’s internal structure is going to react to ground consolidation and stabilisation.

How deep into the ground do you inject?

Injection depth can be critical to ensuring long-term ground consolidation. Each situation varies and the injection depth is determined by the state of the ground. That’s why we inject our resin at multiple and different depths varying between 800mm and 3.5m.

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.

What does Resinject provide on site?

Our crew work from a self-contained mobile unit. We generate our own power and bring all the tools and products required to carry out the works.

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 do I have to do before the 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.

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.

Will there be any need for digging around the building?

If there are utility services in close proximity to the injection points, we may have to clear some area for a visual inspection. Otherwise, only small holes are drilled to allow our product to be injected. These are sealed with non-shrink grout upon completion.

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.

How do you ensure perfect levelling?

On arrival, our crew start by confirming the levels recorded in the initial assessment. We then employ laser equipment to monitor the lifting closely throughout the process, ensuring levelling that is precise to the millimetre.

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 from occurring.

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.

How long does it take for the resin to cure?

Our resins cure in minutes; once the injection is completed, no further chemical reaction will take place. For example, Driveways and factory floors can be used immediately after the clean up.

What geographic area do you service?

We have qualified assessors and technicians in NSW, ACT/SOUTHERN and QLD.
