Resin Injection Repairs in Portsmouth

Resin Injection Expert in Portsmouth, Hampshire

Structural Repairs provides resin injection — a high-performance method for stabilising foundations across Portsmouth and the greater Hampshire area.

With decades of structural repair experience, we deliver “new or better” results — safely and without excavation.


What Is Resin Injection?

Resin injection is a controlled process used to restore movement-affected structures. In essence:

  • A low-viscosity resin is pumped at controlled pressure into voids beneath structures.
  • As it expands, it fills and seals the affected area.
  • The technique strengthens structures without major excavation.
  • It’s often called a “no-dig” or “minimal disruption” alternative to underpinning.
  • Many projects are carried out with minimal downtime.

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

When To Consider Resin Injection

Resin injection can address issues such as:

  • Subsidence due to poor soil conditions.
  • Voids or hollow zones from poor compaction.
  • Cracks in concrete or masonry risking further damage.
  • Structural alterations needing additional support.
  • Soft or compressible subsoils.

If ignored, such conditions can lead to:

  • Progressive cracking
  • Damp and mould
  • Safety hazards
  • Contaminated runoff

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

How Structural Repairs Works

1. Survey & Diagnosis

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

  • Comprehensive visual survey
  • Crack mapping and level monitoring
  • Geotechnical sampling where required
  • Settlement evaluation

2. Design & Specification

A tailored repair strategy is developed to suit the structure:

  • Material specification tailored to site conditions
  • Design of the injection plan
  • Health and safety planning

3. Preparation & Port Installation

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

  • Core sampling
  • Instrumented verification
  • As-built documentation

4. Resin Injection Execution

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

  • Sequential injection for even distribution
  • Monitoring of uplift and soil compaction
  • Verification of fill and structural response

5. Quality Control & Testing

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

  • Crack sealing and preparation
  • Positioning of injection tubes
  • Pre-injection testing

6. Aftercare & Maintenance

  • We provide ongoing support to help maintain long-term performance:
  • Future advisory support
  • Performance monitoring over time
  • Preventative maintenance advice

Why Resin Injection Works So Well

This approach outperforms many traditional techniques in terms of speed, efficiency and overall impact:

Low-disturbance installation — projects remain fully functional with little mess.

Immediate structural improvement — often completed within hours.

Precision targeting — treat only where needed without unnecessary disruption.

Ingress prevention — helps prevent water penetration.

Minimal structural impact — ideal for sensitive structures.

Efficient and economical — thanks to faster project turnaround.

In many projects, results are “as good as new — or better”, providing long-term assurance.

Consequences of Leaving Problems Untreated

Delaying repair can have unexpected consequences:

Risk to occupants — progressive instability.

Environmental impact — moisture and chemicals entering the structure.

Freeze-thaw cracking — issues that multiply quickly.

Insurance complications — urgent interventions cost more.

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

Resin Injection FAQs

Is resin injection permanent?

Yes — when professionally managed, it offers permanent stabilisation.

Can resin injection lift floors or foundations?

Yes — controlled expansion allows partial or full re-levelling.

Is resin injection disruptive?

Very little. Most work is clean and completed quickly.

Is resin injection safe for nearby structures or utilities?

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

How much does resin injection cost?

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