Resin Injection
Resin injection is a modern, minimally invasive technique for stabilising ground conditions and re-levelling structures. A specially formulated geopolymer resin is injected through small holes drilled into the ground, where it expands to fill voids, compact loose soils, and lift sunken structures back to level.
Key Benefits
Non-invasive — no excavation required
Completed in as little as one day
Suitable for occupied buildings
Environmentally friendly materials
Real-time monitoring during injection
Immediate load-bearing capability
Pros & Cons of Resin Injection
Advantages
- Fastest ground stabilisation method — often completed in a single day
- No excavation, no heavy machinery, and no mess
- You can stay in your home throughout the entire process
- Resin is permanent, inert, and will not degrade over time
- Real-time monitoring ensures precision and accuracy
Considerations
- •Not suitable for all ground conditions (e.g. very deep voids)
- •May not be appropriate where access beneath the slab is restricted
- •Less effective in highly organic or waterlogged soils
- •Requires specialist equipment and trained operators
How It Works
Survey
Ground penetrating radar and level surveys to map subsurface conditions.
Preparation
Small injection points are drilled — typically 16mm diameter.
Injection
Resin is injected and expands to fill voids and compact soils under real-time monitoring.
Verification
Post-treatment survey confirms ground stabilisation and level correction.
Frequently Asked Questions
How does resin injection work?
A two-part geopolymer resin is injected through small drilled holes into the ground beneath your property. It expands rapidly to fill voids, compact weak soils, and can lift structures back to level — all monitored in real time.
Is resin injection permanent?
Yes. Once cured, the resin is completely permanent, chemically inert, and does not degrade, shrink, or wash away. It provides a long-lasting structural solution.
Can resin injection be used under my home?
Yes, it is one of the most common applications. Resin injection is routinely used beneath occupied homes, and you do not need to move out during the work.
How quickly can I see results?
Almost immediately. The resin cures within minutes and results — such as floor levelling — are often visible during the injection process itself.
