Leak Seal Services in Dover

Leak Seal Services in Dover, Kent

Even a minor leak can become a serious problem if ignored. Water ingress doesn’t just look unsightly — it weakens structures, creates mould and shortens service life.


At Structural Repairs, we offer leak seal services in Dover, 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.

How Leak Sealing Works

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

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

  • Non-invasive process
  • Injection materials react and fill voids to form a durable barrier
  • Suitable across most materials and conditions
  • Quick to apply
  • Long-lasting and resilient

The result? A strong, sealed structure that restores durability 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.
