Cracks in your
foundation.

Cracks in foundation are caused by loss of load bearing pressure. As the footings and foundations are supported by this pressure, compromises in it can lead to cracks in your foundations and footings. Resinject can stabilize your foundation, protecting your property from further damage.

Why do foundations crack?

While foundations are resilient structures, they are highly dependent on the ground upon which they are set on. If the ground beneath the foundation experiences excessive changes or movement, called subsidence, it can transfer forces into the foundation forcing it to crack.

The reasons why the ground beneath your foundation may change and move include:

  • Un-compacted soils
  • Reactive clay soils
  • Soil erosion
  • Insufficient drainage
  • Poor plumbing serviceability
  • Extreme weather conditions – storm water flooding/extreme heat
  • Nearby construction and excavation
  • Excessive forces exceeding foundation design limits

 

Signs of cracks in your foundation:

  • Cracks in internal or exterior walls
  • Cracks above door frames and windows
  • Doors getting jammed against the floor or frame when you close them
  • Floors that slump or spring when you step on them
  • Gaps between your skirting boards and floor

You may not realise that cracked walls and ceilings, and sinking floors are often the result of broken or cracked foundations. If you’re concerned about cracked foundations due to subsidence or settlement, the wellbeing of your entire property could be at risk. Call the experts at Resinject today!

Are cracks appearing throughout your home?

Foundations are built to withstand a barrage of forces acting upon them. So when cracks in your foundation appear it is critical that you take notice and act to prevent them from getting any bigger and compromising the entire structure of your property.

Foundation crack repair methods

The key to dealing with subsidence is to introduce enough constants to the ground to support the foundation so as to minimise the risk of future movement. At Resinject, our resin injection approach to fixing cracked foundations is far more cost effective and unobtrusive, with very minimal downtime, compared to traditional underpinning. We consolidate and lift your foundation, re-levelling and re-supporting footings back to their original state as conditions allow.

A long-term solution for cracks in your foundation

We work with the best chemical resin that is designed, made and certified to an Australia standard. We inject our resin at different depths, supporting the existing footings and increasing the load bearing capacity of the soils surrounding them. We offer a 50 year warranty on our product against shrinkage.

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

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.

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.

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 and or dependant on geo-technical reports. That’s why we inject our resin at multiple and different depths varying between 800mm and 3.5m.

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 areas 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
