TECHNOLOGY · NO-DIG LEAK SEALING

No-dig leak sealing. Considered carefully.

No-dig internal leak sealingVisible blue water spray is suppressed as sealing particles deposit into the leak path. One gel treatment volume travels from the right-hand connection toward the leak, stays while sealing, then moves back to and exits through the same access connection. 03 / ORIGIN NO DIG · LEAK SEALINGSeal the leak from inside.Controlled delivery · particle deposition · residual recovery Leak One accessInject ↔ recover Normal flow →← Controlled treatment pressure ONE CONTINUOUS TREATMENT VOLUMELeak visible → material travels → particles seal leak → residual material returnsGel / fluid and particles are illustrative; sealing particles retained at the leak are not recovered.Exact return-through-entry method requires confirmation against the applicable Origin work method.

Work from existing access,
where conditions allow.

Some internal leak-sealing methods can be introduced through existing access points, reducing the need to excavate the full route. The pipe's condition and geometry, available access and surrounding site constraints affect suitability; excavation or pipe replacement may still be needed.

Method suitability

Use depends on the leak path, pipe material, operating conditions and the verified requirements of the applicable method. This approach does not structurally restore every pipe defect.

  • Difficult excavation access
  • Pipelines beneath roads or landscaped areas
  • Suitable pipelines with an appropriate leak path

Suitability depends on pipe condition, access, geometry and verified method requirements.
