Extreme weather activity in recent years, including heavy flooding, has demonstrated just how vulnerable properties in Brisbane and throughout Queensland can be. Subsidence, which is the downward shifting of the ground – often caused by the likes of erosion, extreme weather and manmade factors like construction and development – can lead to property foundations sinking along with the soil. One of the most effective methods of minimising the risk, or repairing the damage caused by subsidence, is chemical underpinning.
For trusted and experienced underpinning Brisbane wide, and throughout the Gold Coast and other regions of Queensland, contact the professionals at Resinject.
How The Symptoms of Ground Subsidence May Affect Your Property
Whether you’re a homeowner, or you own a commercial or industrial property, it may be susceptible to the effects of subsidence. If the soil beneath the foundations of your property doesn’t have suitable underpinning, subsidence may cause the following symptoms:

Sunken or sinking foundations

Sunken or sinking concrete slabs

Uneven floors

Cracked walls

Jammed doors and windows

Holes and voids

Unlevel structures and more
Effective resin injection underpinning can help to remedy these symptoms. The resin is Australian-made, complies with Australian standards and is non-toxic. Our resin injection process is largely non-invasive. We inject it into the impacted area of the soil; it expands outwards and downwards, filling any holes and providing additional strength to the soil which helps restore evenness and stability to your property.

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.
