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

1

Survey

Ground penetrating radar and level surveys to map subsurface conditions.

2

Preparation

Small injection points are drilled — typically 16mm diameter.

3

Injection

Resin is injected and expands to fill voids and compact soils under real-time monitoring.

4

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.
