Leak Seal Services in Plymouth, Devon

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


At Structural Repairs, we offer leak seal services in Plymouth, 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 sealants into cracks 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
  • Resins expand and bond to form a flexible barrier
  • Effective for concrete, masonry, foundations and basements
  • Low disruption to operations
  • Permanent, flexible and maintenance-free

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

Leak Seal FAQs

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.
