With extensive of hands-on specialist knowledge, we deliver “new or better” results — with confidence and with minimal disruption.

What Is Resin Injection?

Resin injection is a controlled process used to repair structural cracks. In essence:

A low-viscosity resin is delivered through discreet ports into weakened soil zones.
As it expands, it re-supports the structure.
The technique stabilises structures without major excavation.
It’s often recognised as a “no-dig” or “minimal disruption” alternative to underpinning.
Many projects are finished quickly.

By working directly within the soil or structure, resin injection eliminates voiding while maintaining the property’s appearance and reducing site disruption.

When Resin Injection Is Needed

Resin injection can eliminate issues such as:

Ground movement due to poor soil conditions.
Underground cavities from washout.
Fractures in walls or floors risking further damage.
Structural alterations needing additional support.
Soft or compressible subsoils.

If left untreated, such conditions can lead to:

Progressive cracking
Damp and mould
Safety hazards
Soil instability

Resin injection is a cost-effective solution that rebuilds before more serious damage occurs.

Common Indicators of Subsurface Issues

You may need resin injection if you notice any of the following:

Horizontal or vertical cracking in concrete

Movement under footfall

Sticking doors or windows

Gaps appearing between floors and walls

Ground depressions

If you recognise these warning signs, Structural Repairs can arrange a no-cost survey to check if resin injection is needed.

How Structural Repairs Works

1. Survey & Diagnosis

We begin with a full assessment of the affected area, including:

Detailed site inspection
Crack mapping and level monitoring
Geotechnical sampling where required
Assessment of load paths

2. Design & Specification

A tailored repair strategy is developed to suit the structure:

Selection of the correct resin type
Determining injection pressures and sequence
Preparation of access and utility clearance

3. Preparation & Port Installation

Before injection begins, we prepare the structure and install access points:

Bond checks
Post-injection monitoring
As-built documentation

4. Resin Injection Execution

The resin is injected with precision and real-time monitoring:

Controlled pumping
Monitoring of uplift and soil compaction
Injection continues until design criteria are achieved

5. Quality Control & Testing

After injection, we ensure the repair meets required performance standards:

Surface cleaning
Positioning of injection tubes
Pre-injection testing

6. Aftercare & Maintenance

We provide ongoing support to help maintain long-term performance:
Future advisory support
Scheduled inspection visits
Optional integration with other services

Benefits of Resin Injection

Resin injection offers numerous advantages compared to conventional underpinning or excavation methods:

Low-disturbance installation — properties stay in operation with little mess.

Rapid curing — often completed the same day.

Exact control of injection points — treat specific problem zones without unnecessary disruption.

Ingress prevention — helps prevent future deterioration.

Low added mass — ideal for sensitive structures.

Budget-friendly — thanks to faster project turnaround.

Many clients experience long-lasting improvement and renewed confidence in their building’s integrity.

Risks of Delaying Resin Injection

Delaying repair can have serious consequences:

Potential for injury — movement of structural elements.

Soil contamination — moisture and chemicals entering the structure.

Reinforcement corrosion — issues that multiply quickly.

Higher repair bills — claims may be rejected.

Resin injection provides a timely fix, keeping your property safe, compliant, and ready for long-term performance.

Resin Injection FAQs

Is resin injection permanent?

Yes — when properly designed, it offers permanent stabilisation.

Can resin injection lift floors or foundations?

Yes — calibrated pressure allows partial or full re-levelling.

Is resin injection disruptive?

Very little. Most work is quiet and completed quickly.

Is resin injection safe for nearby structures or utilities?

Yes — all works are monitored to avoid displacement or utility interference.

How much does resin injection cost?

Generally affordable compared to rebuilding, thanks to reduced labour and downtime.
