About Resin Injection

What is resin injection?

Resin injection is a modern ground engineering technique that uses expanding polyurethane resin to fill voids, stabilise soil, lift concrete slabs, and repair subsidence. The resin is injected through small holes and expands to fill spaces, strengthen ground, and provide structural support.

How does resin injection work?

We drill small holes (typically 16mm diameter) into the affected area and inject expanding polyurethane resin under controlled pressure. The resin expands to fill voids, bind soil particles, or lift structures. It cures within minutes, providing immediate strength and stability.

Is resin injection better than traditional methods?

Resin injection offers several advantages over traditional methods: it’s faster (days vs weeks), more cost-effective (typically 50-75% less expensive), non-invasive (no excavation), and provides immediate results. It’s particularly effective for subsidence repair, void filling, and slab lifting.

How long does resin injection last?

Resin injection provides a permanent solution. The polyurethane resin doesn’t degrade, maintains its strength indefinitely, and is unaffected by moisture or ground conditions. We back all our work with comprehensive warranties.

Is resin injection environmentally friendly?

Yes. Our polyurethane resin formulations are eco-friendly and won’t contaminate soil or groundwater. The process produces minimal waste, requires no excavation or disposal of materials, and has a significantly lower carbon footprint than traditional methods.

Cost & Pricing

How much does resin injection cost?

Costs vary depending on the specific application, extent of the problem, property size, and ground conditions. As a guide, resin injection typically costs 50-75% less than traditional underpinning or concrete replacement.

Do you offer free assessments?

Yes, we provide free site assessments and no-obligation quotes. Our experienced engineers will visit your property, assess the problem, and provide a detailed quote with no commitment required.

Is resin injection covered by insurance?

Many home insurance policies cover subsidence repair, which may include resin injection. We recommend checking your policy or speaking with your insurance provider. We can provide detailed reports and documentation to support insurance claims.

Are there any hidden costs?

No. Our quotes are comprehensive and include all materials, labour, and completion of the work. There are no excavation costs, disposal fees, or unexpected extras. What we quote is what you pay.

Project Timeline

How long does a typical project take?

Most residential projects are completed in 1-2 days. Subsidence repair, void filling, and slab lifting can often be done in a single day. Larger commercial projects may take longer, but are still significantly faster than traditional methods.

How quickly can you start work?

We aim to schedule work as quickly as possible after your assessment. Depending on our current workload, we can often start within 1-2 weeks of your initial enquiry. Emergency work can sometimes be accommodated sooner.

Do I need to move out during the work?

Usually not. Most resin injection work is carried out externally with minimal disruption to your home. You can typically remain in your property throughout the process. We’ll advise you during the assessment if any temporary relocation is necessary.

When can I use the treated area after completion?

Immediately in most cases. The resin cures within minutes, and treated areas can bear full loads within 15 minutes to an hour depending on the application. We’ll provide specific guidance for your project.

Technical Questions

Will resin injection damage my property?

No. Resin injection is non-invasive. We drill small holes (about 16mm) which are sealed after completion. There’s no excavation, no damage to landscaping, and minimal visible evidence of work once completed.

Does resin injection require planning permission?

No. Resin injection doesn’t require planning permission as it’s a repair method rather than new construction. This saves considerable time and avoids administrative complications.

Can resin injection be used on any soil type?

Yes. Resin injection is effective across all soil types including clay, sand, silt, and made ground. Our engineers assess your specific ground conditions and adjust the injection parameters accordingly.

What if the problem returns?

Our resin injection provides permanent solutions, and problems rarely return when properly applied. All our work is backed by comprehensive, insurance-backed warranties. If any issues arise, we’ll address them under the warranty terms.

Can you work in all weather conditions?

Yes. Unlike concrete work which requires specific weather conditions, resin injection can be performed in most weather including rain and cold temperatures. This allows for more flexible scheduling and faster project completion.

Specific Services

Can you repair cracks in my walls?

Yes. If cracks are caused by subsidence or foundation movement, resin injection stabilises the underlying cause. Once stabilised, surface cracks can be filled and repaired by a builder or decorator.

Can you lift my sunken driveway?

Yes. Slab lifting is one of our core services. We can lift and re-level sunken driveways, patios, paths, and garage floors to their original position quickly and cost-effectively.

Do you repair basement water leaks?

Yes. Our water sealing service uses expanding resin to seal cracks, joints, and leak points in basements and underground structures, creating permanent waterproof barriers.

Can you strengthen foundations before an extension?

Yes. Our ground improvement and structural support services can strengthen existing foundations to support additional loads from extensions or extra stories.

Do you work on commercial properties?

Yes. We provide all our services for residential, commercial, industrial, and infrastructure projects. We have experience with warehouses, offices, car parks, roads, and more.
