Specialist repair — high value, low frequency
When the problem is the pipe, not what's inside it
Trenchless rehabilitation — including CIPP (cured-in-place pipe) lining — repairs a cracked, offset or collapsed drain or sewer line from the inside, without breaking floors, paving, or landscaping to reach it.
How it works, briefly
CCTV confirms the damage
This starts as a CCTV inspection finding, not a standalone request — you need to know exactly what's broken and where.
A liner is inserted
A resin-saturated felt liner is fed into the existing pipe, positioned across the damaged section.
It's cured in place
The resin hardens against the pipe wall, forming a new, jointless pipe inside the old one.
Flow is restored
No excavation, no broken flooring, no lengthy building disruption.
Honest scope note
This is a specialist, technically demanding repair method — not every commercial drainage contractor runs a lining crew in-house. We route trenchless enquiries to specialists set up specifically for this work, which sometimes means a slightly longer matching step than a same-day jetting job. If your case turns out to need a full open-trench replacement instead, that's a legitimate answer a specialist may give you after inspection, not a sign of the wrong provider.
Common questions
What is CIPP pipe lining?
Cured-in-place pipe (CIPP) lining inserts a resin-saturated liner into the damaged pipe, which is then cured to form a new, jointless pipe inside the old one — repairing the line without excavating it.
When is trenchless repair the right call instead of jetting?
When a CCTV inspection shows a structural problem — a crack, an offset joint, a collapsed section, or repeated root intrusion through a damaged joint — rather than just grease or scale build-up. Jetting clears what's blocking the pipe; it can't fix a pipe that's physically broken.
Is trenchless repair cheaper than digging up the pipe?
It avoids excavation costs, reinstatement of flooring or paving, and the operational disruption of a dig — which is usually the bigger saving for an operating commercial building than the lining material itself. Actual cost depends heavily on pipe length, diameter and access.
