Fantastic job resin underpinning our bungalow. Everything was explained clearly and the price was less than other quotes.
Steve WatsonFriendly, professional and thorough service. The issue was explained in a way that was easy to understand.

susan fishendenKnowledgeable, friendly and very honest. They advised that the house did not need underpinning.

What we do and why it matters
Not every crack is subsidence, but movement should not be ignored. If the ground is still moving, decorating over cracks or forcing doors to close is only a short-term fix. We help you understand the cause, stabilise the support and protect the property before repairs, sales or insurance decisions become harder.

The person who assesses your ground carries out the works
No sales targets, no standardised solutions and no one arriving on site who was not part of the original conversation. The person who assesses your ground is also the person on the phone when you have a question.
Soil science
Understanding how ground behaves, why clay shrinks in dry summers and swells in wet winters, how bearing capacity changes with moisture, and where a problem actually originates.
Building knowledge
Knowing how a structure loads the ground, how movement transfers through a building, and what else might be contributing to the visible symptoms.
Technical resin knowledge
Product selection based on soil type, moisture content and required outcome is a technical decision, not a catalogue choice.
Honest advice
If resin injection is not the right answer for your situation, we will say so before you spend money on the wrong repair.
The team behind every job
RFR operates with a trusted network of specialist advisors covering soil science, structural engineering, geophysics and building conservation. Where a job demands independent ground investigation, third-party verification or specialist structural input, that expertise is drawn in directly.
Depth without the overhead
Clients get the depth of a large consultancy without the unnecessary layers. At the centre is Ruairi Lennon, who spent years as a soil science researcher before moving into building, renovation and land reclamation. He coordinates the technical network, carries out every assessment and remains the single point of contact from first call to completion.
Small enough to care. Capable enough to deliver.
When you call, you reach someone who knows your job. No hold music, no departments and no handoffs. On a job involving your foundations, that matters more than it might seem.
Our guarantees
Some of the strongest guarantees in the industry
Every RFR project is backed by clear documentation, defined treatment areas and honest advice about what is and is not covered.
25-Year Company Guarantee
We stand behind our work with a 25-year guarantee covering workmanship and the performance of the injected resin system within the defined treatment area.
10-Year Insurance-Backed Guarantee
Where required, RFR provides a 10-year IBG underwritten by an approved insurer. Required by many mortgage lenders and insurers, documentation is provided on completion for lenders, insurers and future property records.
Clear scope from the start
The guarantee covers stabilisation of the treated ground and resin performance within the agreed treatment zone. External causes such as unresolved drainage defects are explained upfront.
Environmental reassurance
Safe for the ground, safe for the environment
RFR uses cured resin systems designed to remain stable in the treated ground without negative impact on surrounding groundwater or soil.
MDI-based polyurethane systems
The resins used by RFR are specialist MDI-based polyurethane systems selected for ground stabilisation and resin injection work.
Chemically inert once cured
Once injected and cured, the resin is chemically inert. It does not leach, does not degrade over time and becomes a permanent, stable addition to the ground.
Technical data available
Material safety data sheets and technical data sheets are available on request for clients, engineers, insurers and professional teams.
Precision injection
We only inject where it is needed - and we can prove it
Where the situation warrants it, RFR commissions or works alongside independent geophysical surveys, including Electrical Resistivity Tomography (ERT), to map the exact location and depth of ground anomalies before a single lance goes in the ground.
The result: less resin, lower cost, better outcome
On a recent industrial unit project in the West Midlands, a 70-metre warehouse elevation affected by subsidence was assessed with a pre-injection ERT survey by independent specialists. The injection programme was designed around the data, and a post-treatment survey confirmed the result.
Independent verification
"This process of prior and post surveys greatly reduced the required resin and targeted the key areas."
The report was prepared and signed off by two Chartered Geologists registered with the Geological Society of London.

What Is Subsidence?
Subsidence is downward movement of the ground that causes part of a building to lose support. It can create cracks, distortion, uneven floors and problems with doors or windows.

Signs of Subsidence
Subsidence does not always look dramatic at first. Small changes that repeat, widen or appear in clusters can be more important than one isolated hairline crack.

Resin Injection vs Underpinning
Underpinning is well known, but it is not the only way to stabilise a building. Resin injection is a modern alternative for suitable ground improvement and foundation strengthening projects.

Foundation Repair Costs
Foundation repair pricing depends on the cause, the size of the treatment zone, access and the evidence required. A quick quote without understanding the property is rarely helpful.

FAQ
Frequently Asked Questions
Straight answers before you book a survey.
How do I know if I need foundation repair?
If you have widening cracks, sticking doors or windows, uneven floors, gaps around frames or a surveyor has raised subsidence concerns, it is worth arranging an assessment before cosmetic repairs.
How quickly can you help?
Send photos and your postcode through the get started form and the team can triage the issue quickly. Free home survey requests include one preferred date and time.
Do you use traditional underpinning?
Our focus is resin injection and no-dig ground stabilisation. If a property needs a different engineered solution, we will be clear about suitability.
Can I stay in the property during the work?
In many domestic resin injection projects, yes. The process is usually far less disruptive than open excavation, although access and safety arrangements are confirmed for each job.
Do you cover the whole UK?
Yes. Resin Foundation Repair Ltd works across the UK from Scotland to Cornwall, while still providing local area pages for common North West search locations.
