No dig drain repair can address suitable defects without opening a trench along the full length of the pipe. We use internal repairs where CCTV findings show that the pipe can accept them, particularly beneath paving, floors or other established surfaces.
No Dig Drain Repair
No dig drain repair for suitable defects using internal patches or liners, with excavation where the pipe cannot be repaired from inside.

Patch or longer liner
The position and spread of damage help determine whether a local patch or longer internal repair is appropriate.
Access and excavation
Existing chambers can reduce surface disturbance, although local excavation may still be needed for access or severe damage.
Patch repairs and longer liners
An isolated crack or joint may suit a short patch, while damage spread along a run can justify a longer liner. Both methods need a prepared bore and suitable access. Severe displacement or collapse can obstruct installation, so local excavation may still be required before internal repair is possible.

What no-dig repair still involves
The pipe still needs cleaning and preparation before a patch or liner can be installed. Connected facilities may need temporary restrictions while the work is carried out, even when most of the surface remains untouched.
Access and pipe geometry
An existing chamber must provide enough room for the installation equipment, not merely a view of the pipe. Tight bends, diameter changes and branches can also limit access. These factors are checked before an entirely internal repair is confirmed.
No Dig Drain Repair: common questions
Does no dig mean no disruption?
The method can reduce digging, but chamber access, equipment space and temporary drainage restrictions still matter.
Can a completely collapsed drain be lined?
A fully obstructed bore cannot accept a liner normally. The failed section may need replacement before adjoining lining.
Is a survey needed before choosing this method?
The pipe's condition and access must be established before an internal repair is confirmed.
Can a local excavation be combined with no-dig work?
Yes. A small access or replacement section can enable lining elsewhere where the pipe is suitable.
Will no-dig repair correct a badly laid pipe?
It generally follows the existing route. Serious fall or alignment problems may still require replacement.
