Foundation Crack Repair

Across NSW, QLD and ACT!

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 stabilise 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 repair is often required for older houses as they have usually withstood more force changes over the years.

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.

Frequently Asked Questions

Leaving an unstable structure can cause further issues. By having an early assessment/treatment, will save further costs and lessen further damage from occurring.

Most residential jobs are finished within a few hours. Bigger projects may take over a day; your Structural Consultant will discuss the time frame as part of the free site assessment and quoting.

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.

With over 100 years of combined experience, Resinject exclusively uses an Australian-engineered resin that can be injected to depths of up to 6.5 meters when needed, ensuring proper re-support is installed. We do offer a 50 year guarantee against shrinkage with our product.

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 6.5m.

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.
