What Are Leak Seal Services?

Leak sealing is the process of applying specialist resins 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
  • Resins expand and bond to form a durable barrier
  • Effective for concrete, masonry, foundations and basements
  • Low disruption to operations
  • Permanent, flexible and maintenance-free

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

Common Leak Repair Queries

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.
