Protect the structural integrity of your property from the potential risks of subsidence with the expertise and knowhow of Resinject. We provide services in underpinning Canberra wide, as well as throughout the Australian Capital Territory. These services are designed to minimise the potential for damage to your residential, commercial/industrial or government property caused by subsidence, and can assist with everything from concrete levelling to house foundation repairs and much more.
Helping Remedy the Symptoms of Subsidence
Subsidence, or the downward shift of soil, is often caused by erosion and changes to the moisture level below the ground surface. It can also be caused by man-made factors such as vibrations caused by nearby construction and development work. The downward movement, or sinking, of the soil can cause the foundations of your property to sink as well. This can result in a number of symptoms that may cause significant problems for your property including:

Sunken or sinking foundations

Sunken or sinking concrete slabs

Uneven floors

Cracked walls

Jammed doors and windows

Holes and voids

Unlevel structures and more
We have developed a process that is largely non-invasive and won’t take up much of your time. By injecting our non-toxic, Australian made RSJ170 resin into the affected areas of your soil, we can restore its stability and improve its strength. This method of underpinning is highly effective in everything from house foundation repairs to floor levelling and other concrete repair needs.

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.
Drawing on over 60 years’ combined experience, Resinject only uses a resin that has an Australian Standard resin and can be injected to a depth of up to 3.5 metres if necessary with the necessary re-support 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 3.5m.
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.
