Need house foundation repair services?

Subsidence causes movement in the ground beneath your foundations, exerting stress on your foundation which can damage your home.

Signs of subsidence at your home:

Fixing Cracked Walls

We drill injection holes below foundations and into the subsoil centered at approximately 1.2m to 1.5m. This allows us to inject at multiple depths forming 'piers' to support the structure over the affected area.

I had three quotes for a major slab extension job. Resinject was by far the most comprehensive and detailed in scope. Richard, the technical assessor was able to propose two scenarios relevant to the site which was complicated by plumbing issues. When Julio, the project manager arrived on site, he was well briefed. He and the team did a great job, keeping me informed of the progress. The slab has been stabilised and underpinned with good lift achieved. Thank you Resinject.

I submitted a request for an on-site inspection and was contacted by Richard the same day. He was extremely knowledgeable and made arrangements to come to my place within days.Not only did he show up on time he gave me a courtesy call 30 mins before arriving. After a thorough inspection Richard gave me an honest account that my place didn’t require work currently.My place is a federation home on Sandstone footings which is moving due to moisture content. Richard gave me things to look out for and an understanding of what was happening to the sub floor.There was no sales pitch just an honest guy. If/ when I need work done I will definitely be calling him!

We recently got Resinject Pty Ltd to do some underpinning done at our house in Junction Hill NSW, and we were very happy with the service they provided. Starting with a very professional detailed written quote issued by Nathan, covering all aspects of the job, through to Chelsey keeping me informed on when the work was to be done & then arranging the final date, then to Matt and his professional team who did the actual work and walked me through the whole process onsite. Basically the whole job from start to finish couldn't have gone any smoother. I have no problems at all in recommending this company to do underpinning should it be required. Cheers, Pat McCauley

Professional, efficient, and excellent open communication. Julio was a delight to work with and everything was done by the time we got home from work! Fast quote and turn-around to the injection happening, even in Dubbo. Very happy with service and communication throughout. Thank you!

Richard came to inspect my house yesterday. He is incredibly helpful, very knowledgeable, trying to find the root problem and best solution (instead of providing just a short-term quick fix) to fix the crack problem in the back part of the house. Although at the end, he believed his company couldn't offer the right product for my house, he was keen to suggest someone to help first explore if water draining issue is the root cause, and if it is then once resolved, re-bricking would be the way to go (and perhaps with resin to stabilise the foundation if necessary during re-bricking). The house also got cracks on the retaining wall, and again he made very good suggestions on how to address the situation. What really impressed me is Richard's integrity and working philosophy: keeping the company's reputation is more important than just making money for his family business. I would highly recommend Resinject to anyone who needs to fix cracks and related problems in their house.

I had issue with my cracks in walls due to problems with the foundations. I called Resinject and Richard came out within a week and gave me a quote on the day. The next day I had the written quotation in my email. The guys came out on the appointed day, on time and did an excellent job.Resinject has treated us like ‘family’. Resinject’s response during COVID-19 across the job and also assisting us with payment has helped us to get our house corrected.I would always recommend them to anyone having similar issues. They are highly ethical company. I usually do not say this, but proud to see an Australian company delivering great service to our community.

Richard was very courteous, trustworthy and transparent when explaining what Resinject could and could not do.The team, led by Adam, who came to do the job continued this culture of transparency and courtesy, showing me exactly what they were doing and why, and setting expectations that the goal wasn't necessarily to close gaps but to reinforce the foundations of our home to prevent future movement.Indeed the house reacted very well to the job as you can see from the photo with some closed up gaps, but there were also some gaps that opened slightly wider too, which was emphasised before the job started. However, after the recent large downpours, I didn't notice any visible change in gap sizes in our home, which meant the underpinning has been done its job so far, which is pleasing to see.My family also commented that there was less cleaning required after the underpinning due to gaps closing up between cornices and the wall. In the past, debris would be falling from the roof cavity on a regular basis.Adam was also careful not to damage any recent new extensions we added to the home as well, which I appreciate.All in all, except for needing to seal up a few holes in the house from drilling and adjusting the strike plates on our doors after the movement in the house, I was very happy with the final result.Thank you Resinject!

Frequently asked questions

Will the wall cracks be eliminated?

Our first priority is to minimise the risk of future 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 1-3 mm 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 6 – 8 weeks after works before carrying out any cosmetic repairs.

What are the guarantees of your product?

Drawing on over 60 years’ combined experience, Resinject has a resin that has an Australian Standard. This resin can be injected to a depth of up to 3.5 metres ensuring support on all points is installed. This is why we offer a 50 year warranty against shrinkage of the product.

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 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.

Drawing on over 60 years’ experience for dependable, lasting results - with Resinject you will get nothing less!
