Are your floors sinking? When this happens, it reduces the carrying capacity and limits the designed use of a slab, whether it be traversing with heavy machinery, heavy equipment or heavy storage for logistical and commercial warehouses. Sinking floors can not only cause significant structural problems but also downtime for homes and businesses.

What causes sinking floors?

Sinking floors and uneven floors are usually caused by voidage that then leads to subsidence. This means that the ground beneath your flooring may be moving in response to a variety of factors such as un-compacted fill, voidage from compromised plumbing services, such as storm water, sewer, or leaking water mains. This will result in the moisture content of the soils changing: in reactive clays, this will result in the ground expanding and contracting forming voids; and in sandy loams and sands, these factors will contribute to washouts, again compromising the load bearing on the slabs. Other factors affecting the ground are poor drainage and poor site design that compromise the bearing capacity of the ground. Extreme weather factors can also impact on structures.

What are the signs of a sinking floor?

If you worried about sinking floors caused by subsidence or voidage, there are signs:

  • Cracks in your external and/or internal walls and ceilings
  • Cracks in external and/or internal concrete slabs, cement, steps or floors
  • Doors that are jamming against the floor or frame when you close them
  • Areas in your floor that slump or sound “hollow”
  • Variation of your “skirting boards” where the slab is lower than originally intended

Subsidence and voidage can represent a serious structural problem to the integrity of your home, business or worksite and a potential hazard to you and those around you. This can cause Work Health Safety issues relating to injuries sustained by forklift operators from traversing uneven slabs, not to mention the maintenance costs of the actual forklift. If you notice your floors are sinking, call the experts at Resinject!

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.

How to fix sinking floors

At Resinject we stabilise and support sinking floors by injecting our resin under the slabs, void filling the affected area, and increasing the load bearing capacity of the soils which are 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 – “stitching” the adjoining slabs together is a standard operation when treating industrial slabs.

A long-term solution for your sinking floor

At Resinject we always provide long-term solutions to fix your sinking floors. This is because we address the root cause of the problem: subsidence and voidage. The high quality chemical resin that we use to stabilise your slabs and foundations is not only certified to Australian standard but so tough, durable and dependable that we provide a 50 year warranty on our product.

Reliable, communicated every step, very happy with end result

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

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

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.
