Leaking drain repair begins by establishing whether wastewater is escaping and where the defect lies. Damp ground or persistent odour can justify an investigation, but neither proves that a drain is responsible. We use the findings to recommend a repair for the identified fault.
Leaking Drain Repair
Leaking drain repair based on CCTV findings and, where needed, leakage testing to identify the fault.

CCTV and leakage tests
CCTV can identify possible leak points, while watertightness may need a separate specified test.
Repairing the fault
Patch repairs, liners or excavation are selected according to the defect and surrounding pipe condition.
Visible defects and leakage testing
CCTV can show a crack, open joint or displaced pipe, but an image does not establish the watertightness of every joint. A suitable test may be needed where leakage has to be investigated directly. Water can also travel through surrounding ground, so the wettest surface point may not sit above the defect.

Repairing the source of the leak
A patch or liner can repair suitable cracks and joints. Significant displacement or a broken connection may require excavation. The repair covers only the identified section. Restored flow does not prove that every possible source of leakage has been resolved, and any required leakage testing remains a separate check.
Evidence after repair
Completion footage shows the accessible condition of the repaired section, while any specified leakage test answers a different question. If the investigation cannot establish the source of wet ground, that uncertainty remains clear rather than being attributed to the nearest visible drain defect.
Leaking Drain Repair: common questions
Does a damp garden prove the drain is leaking?
Other sources include groundwater and leaking supply pipes. The investigation should establish which source is responsible.
Can a drain leak while water still flows?
A defective joint or crack may leak while the pipe still carries flow.
Will drain cleaning stop a leak?
Cleaning removes deposits and can expose damage. Sealing a leak requires appropriate repair of the defect.
Can the surface stay wet after a drain is repaired?
Ground may take time to dry, and another water source may exist. Continued wetness needs interpreting against the repair findings.
Does lining repair leaking joints outside its length?
No. The repair covers the defined section; other joints require their own assessment.
