What is crack injection repair used for?

Crack injection repair is used to fill and seal cracks in concrete or brickwork. It can help with structural stabilisation, leak sealing, and limiting further deterioration where moisture or movement is affecting the structure.

What is the difference between epoxy and polyurethane injection?

Epoxy injection is generally used when the aim is to bond and strengthen the cracked section. Polyurethane injection is often chosen for active leaks because it can expand into small gaps and help block water ingress.

Can injection repairs stop water coming through concrete?

They can be very effective where water is travelling through cracks, joints, or small voids. The success of the repair depends on the source of the leak, the condition of the substrate, and using the right material for the job.

What you can expect from us

5-year crack repair guarantee

Lasting protection for resin, epoxy, and polyurethane crack sealing.

Complimentary site evaluation

On-site damage review to determine whether epoxy or polyurethane injection is required.

Two decades of injection expertise

Skilled application of high-pressure resins to stop active leaks and restore load capacity.

Stopping cracks before they spread

Cracks in concrete and brickwork rarely stay still. We provide resin injection repairs to fill voids, restore continuity, and help stabilise damaged areas before movement or moisture causes bigger trouble. When water ingress is present, this work complements our wider waterproofing services to keep moisture out completely. Epoxy injection is often used where strength matters, while polyurethane injection is useful for sealing active water paths and stubborn leaks.

That makes this kind of repair a practical choice for structural crack stabilisation, concrete crack repair, and brick crack repair without ripping everything out first. We've spent 20 years dealing with concrete problems, and Brick-Crete brings that experience to industrial and commercial sites across Southampton. If water is getting in or a crack is widening, a targeted injection repair can be a far cleaner fix than full replacement.

Choosing the right injection for the job

Not every crack behaves the same, and that's why the repair material matters. Our approach starts with the condition of the structure, the depth of the crack, and whether water ingress is part of the problem. Epoxy resin is suited to bonding and stiffening damaged sections, while polyurethane can expand into fine gaps to create an effective leak seal. We use these methods for water leak injection where seepage is affecting floors, walls, or joints. Around Southampton, Brick-Crete helps you make sense of the problem before any repair work begins.
