Leak Seal Services in Reading

Leak Seal Services in Reading, Berkshire

Even a hairline leak can become a serious problem if ignored. Water ingress doesn’t just look unsightly — it damages structures, creates mould and compromises integrity.


At Structural Repairs, we offer leak seal services in Reading, providing engineered, lasting repairs that restore your structure to “new or better” condition. With decades of proven experience and industry recognition, we deliver solutions that are watertight, durable and compliant.

Understanding Leak Sealing

Leak sealing is the process of introducing specialist resins into joints or defective areas to stop water ingress at their source.

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

  • No need for external excavation
  • Injection materials react and fill voids to form a durable barrier
  • Suitable across most materials and conditions
  • Quick to apply
  • Permanent, flexible and maintenance-free

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

Your Questions Answered

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.
