Have you experienced large washouts, damaged plumbing or extreme weather events that have caused voids and erosion beneath your slabs or infrastructure? If so, Resinject has a sustainable solution for you.
Voids can be found in mining, civil construction, the transport industry, and beneath residential homes. Voids can destabilise your foundations or overlying assets and make them prone to cracks and sinking.
At Resinject, our void filling method uses unique, expanding resin to achieve a rock-solid result. Don’t wait to protect your property or asset. Call Resinject now and get a free, no-nonsense assessment.
How Does Void Filling Work?
In the past, filling voids under concrete meant just one thing – more concrete. Concrete void filling simply plugged the gaps with more of the same materials, and whilst this method is still used, to varying degrees of success, technology has evolved.
At Resinject, our void filling services use a powerful expanding resin. We inject our expanding polyurethane material, which expands to fill even the most hard-to-reach spaces.
The result? An enduring resin, specially formulated to outlast the toughest conditions, that leaves a firm foundation and an unbeatable void filling solution. Simply put, our resins out-perform concrete void filling, any day of the week.
Why Resin is the Best Choice
Filling voids under your concrete or infrastructure can be a quick and simple process. When you contact Resinject for your free assessment, we can walk you through the entire process and explain why our expanding resin injection is the best choice for your asset.
Our Structural Consultant will be in contact, on the same day, to discuss a time to meet onsite to check your foundations and any structural issues you may be experiencing. If we believe our void filling services will genuinely benefit your property or the asset, then we’ll give you a quote and can begin work asap.
This is a powerful approach to slab jacking that offers unbeatable value for money.

Frequently Asked Questions
Yes, voids can be effectively filled using our high-strength, engineered expanding resin injection technology. At Resinject, we inject specialised resin into the affected area, where it expands to fill gaps, compact loose soil, and restore stability. This process strengthens the foundation, prevents further movement, and provides long-lasting support—all with minimal disruption.
As a chemical underpinning company, we fill underground voids using our proprietary high-strength engineered expanding resin, ‘RSJ170’. The process begins by drilling small injection points into the affected area. We then inject a specialised resin that expands upon contact, filling gaps, compacting loose soil, and reinforcing the ground. As it cures, the resin forms a solid, water-resistant foundation that stabilises the area and prevents further movement. This method is quick, non-invasive, and provides long-lasting support for structures affected by subsidence or soil instability.
We use our proprietary high-strength engineered expanding resin, ‘RSJ170’ to fill voids in concrete. This specialised resin is injected through small holes, where it expands to fill gaps, compact the surrounding soil, and restore stability. It’s a fast, non-invasive solution that strengthens the foundation, prevents further movement, and ensures long-lasting support.
Whilst void filling can be a simple process when completed professionally, it is extremely important you do not undertake any repairs yourself.
Incorrect concrete void filling can cause more harm than good, with practices, processes and materials that can ultimately be not fit for purpose.
For this reason, if you are considering any kind of concrete void filling, then we encourage you to contact Resinject today. Our free, no-obligation assessments will help you decide the best strategy for your property.
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.
