Leak Seal Services in Edinburgh

Leak Seal Services in Edinburgh, Lothian

Even a hairline leak can become a significant problem if ignored. Water ingress doesn’t just look unsightly — it weakens structures, encourages damp and shortens service life.


At Structural Repairs, we offer leak seal services in Edinburgh, providing fast, effective repairs that restore your structure to “new or better” condition. With decades of proven experience and certified expertise, we deliver solutions that are watertight, durable and compliant.

What Are Leak Seal Services?

Leak sealing is the process of injecting specialist polymers into cracks or defective areas to stop seepage at their source.

This targeted method uses injection resins such as polyurethane or epoxy to stabilise structures from within.

  • Works internally
  • Injection materials react and fill voids to form a watertight barrier
  • Effective for concrete, masonry, foundations and basements
  • Minimal downtime
  • Long-lasting and resilient

The result? A strong, sealed structure that resists water penetration for years to come.

Frequently Asked Questions

Well, it depends on the structure itself. But in most cases, yes – our range of injection systems can handle active, dormant or pressurised leaks.

Is resin injection permanent?

Yes. Properly designed and applied, it provides a flexible, waterproof barrier lasting decades.

Will I need to excavate?

No. Injection sealing is internal — minimal surface access is required.

Almost never. Ports are removed and finishes restored to blend seamlessly.

Can the building remain in use?
