What causes sunken and/or cracked concrete?

The ground beneath your concrete slabs, flooring or foundation is affected by a variety of factors that can cause changes and movement called subsidence.

This can be due to water washouts, reactive clay soils and damage from surrounding vegetation. As the unstable ground sinks and moves, it will cause the concrete above it to crack, slump, pump and tilt.

What are the signs of sunken or cracked concrete?

Subsidence underneath your concrete can be quite obvious. At residential properties it most commonly presents as a sunken driveway and at commercial/industrial sites it can cause cracked and uneven concrete slab flooring.

 You may be at risk if you’ve noticed concrete flooring or concrete slabs that:

  • Appear sunken – unevenly raised/depressed
  • Have cracked
  • Appear tilted or you have noticed a slant walking over them
  • Show movement between them and other fixed structures like railings or walls
  • Very noisy(clunking) should you have forklifts traversing slabs
  • Water being squished from under the slabs when traversed by vehicles
  • Obvious trip hazards between slabs
  • Homes built on slabs that subside result in cracked walls, sticking doors and windows
  • Visible voids under the slab

If you notice signs of sunken or cracked concrete, your property may be at risk of subsidence. Not only does this compromise the integrity property but can also represent a significant trip and safety hazard to personnel as well as potential expenses on machinery maintenance.

 

Is your site at risk?

Industrial and commercial sites can be established on compromised sub soils such as fill, reactive clays and sandy soils that have not been compacted sufficiently or have been compromised for one reason or another, be it washouts, drainage, or plumbing.

Sunken and cracked concrete repair

At Resinject, we inject our resin under the concrete slabs, void filling the affected area and increasing the load bearing capacity of the soils which is supporting the affected slab. Our re-levelling process is also re-supporting of adjoining areas that could have been compromised due to the subsidence, once re-supported we then “stitch” the slabs together. We also can install piers in necessary situations.

A long-term solution for your sinking or cracked concrete

At Resinject we are not about quick fixes, we provide our customers with long-term peace of mind by ensuring that we treat the principle cause of the problem: subsidence. We work with a high quality resin to stabilise and consolidate the ground under your concrete slab and flooring. Our resin is not only certified to the highest Australian standards but we provide a 50 year warranty on our product.

We provide a high quality service, a high quality product and the best value for money. We pride ourselves on being an industry leader and utilising resin that is 100% designed and made in Australia.

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

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

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.

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 are the guarantees of your product?

Drawing on over 60 years’ combined experience, Resinject use a resin that is certified and has an Australian Standard. It can be injected to a depth of up to 3.5 metres if necessary with the necessary re-support installed. Resinject offer a 50 year warranty on the resin against shrinkage

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.
