Can a drain be relined without digging?

Usually yes. Patch lining and full-length relining repair cracks, root damage and displaced joints from inside the pipe through an existing access point, so the drive or garden is left intact. Excavation is normally only needed where a drain has fully collapsed.

Drainage engineer feeding a resin liner into an inspection chamber on a block-paved driveway

Your drive stays where it is

Patch or full-length relining

Relining (also called CIPP, or cured-in-place pipe) threads a resin-soaked liner into the damaged pipe through an existing manhole or access point, then cures it hard. You end up with a new pipe inside the old one — and a drive, patio or lawn that was never touched.

Quotes on this job vary widely

A localised patch typically costs £300–£600; relining a full run £1,500–£4,000. Two specialists can price the same liner very differently, which is why it pays to compare rather than accept the first number.

Fully collapsed drain, or no usable access? That is excavation work — see drain repairs and excavation.

The decision that moves the price

Relining vs excavation

Both fix the drain. They differ enormously in cost, disruption and how long you lose your drive for.

	No-dig relining	Excavation & replace
Typical cost	£300–£600 patch · £1,500–£4,000 full run	From £1,000 per section
Digging	None — worked through an existing access point	Trench opened over the failed pipe
Time on site	Usually a single day	Several days, plus reinstatement
Reinstatement	Nothing to put back	Paving, tarmac or turf to relay — often a separate cost
Best for	Cracks, fractures, root ingress, displaced joints, leaking joints	Full collapse, severe deformation, no usable access

Cost ranges: industry cost guides, 2026. Your quote depends on pipe diameter, the length being lined and access.

What's involved

How a relining job runs

1. Survey and quote

Relining is priced off a CCTV survey — the report shows what is wrong, where, and how much pipe needs lining. If you already have a report, send it and the quotes get sharper.

2. Clean and line

The pipe is jetted clean and any roots cut out, then the resin liner is drawn or inverted into position and inflated tight against the pipe wall.

3. Cure and sign off

The liner cures hard — ambient, hot water, steam or UV — and a final CCTV pass proves the repair. Ask for that closing footage: it is your evidence the job was done properly.
