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
Completed in as little as one day
Environmentally friendly materials
Immediate load-bearing capability
Non-invasive — no excavation required
Real-time monitoring during injection
Suitable for occupied buildings
Resin Injection — Pros and Cons
Pros
- Minimally invasive with no excavation required
- Most jobs completed within a single day
- Can be carried out in occupied buildings with minimal disruption
- Environmentally friendly, chemically inert materials
- Real-time precision monitoring ensures accuracy
Cons
- Not suitable for all soil types — very soft or waterlogged ground may need alternative methods
- Limited effectiveness for very deep foundation issues
- Requires specialist equipment and trained operatives
- May not be appropriate where extensive structural rebuilding is needed
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. The resin expands rapidly, filling voids, compacting weak soils, and lifting sunken structures back to level — all monitored in real time.
Is resin injection permanent?
Yes. Once cured, the resin is permanent, chemically inert, and does not degrade over time. It provides a long-lasting structural solution that won't break down or wash away.
Can resin injection be used under my home?
Yes, it's one of the most common methods for residential properties. It can be carried out while you remain in your home with minimal noise and no excavation required.
How quickly can I see results?
Almost immediately. Results are often visible during the injection process itself as the ground lifts and stabilises. The resin cures within minutes, providing immediate load-bearing capability.
