Leak Seal Services in Reading

Leak Seal Services in Reading, Berkshire

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


At Structural Repairs, we offer leak seal services in Reading, providing professional 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.

Our Leak Seal Method Explained

Leak sealing is the process of injecting specialist resins 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.

  • No need for external excavation
  • Resins expand and bond to form a watertight barrier
  • Suitable across most materials and conditions
  • Low disruption to operations
  • Long-lasting and resilient

The result? A strong, sealed structure that protects your asset for years to come.

Frequently Asked Questions

Can all leaks be sealed?

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.

Is the repair visible?

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

Can the building remain in use?

Yes — most projects are completed with no operational downtime.
