Leak Seal Services in Leeds, West Yorkshire

Even a hairline 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 Leeds, providing fast, effective 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.

What Are Leak Seal Services?

Leak sealing is the process of injecting specialist resins into voids 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 durable barrier
  • Suitable across most materials and conditions
  • Quick to apply
  • Permanent, flexible and maintenance-free

The result? A strong, sealed structure that restores durability for years to come.

Is resin injection permanent?

Yes. Properly designed and applied, it provides a flexible, waterproof barrier lasting decades.

Will I need to excavate?
