Leak Seal Services in Brighton

Leak Seal Services in Brighton, Sussex

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


At Structural Repairs, we offer leak seal services in Brighton, providing engineered, lasting repairs that restore your structure to “new or better” condition. With over 35 years of proven experience and industry recognition, we deliver solutions that are watertight, durable and compliant.

How Leak Sealing Works

Leak sealing is the process of injecting 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 seal structures from within.

  • Works internally
  • Resins expand and bond 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 restores durability for years to come.

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.
