Excavation means digging down to the failed pipe. It is more disruptive than relining, so it should follow a clear survey and repair plan. When a pipe is crushed or has lost its shape, replacement can be the most reliable option.

Signs this service may help

The pipe is fully collapsed
A section is crushed or badly deformed
Several joints have moved apart
The drain runs uphill or has sunk
A new route or connection is needed
Internal repair equipment cannot reach the fault

Keeping excavation controlled

The aim is targeted access, not digging a whole garden without evidence. CCTV distance readings and locating equipment help place the excavation over the defect.

New pipework must have suitable support, joints and fall. A final flow test or camera check confirms that it connects correctly with the remaining drain.

Reinstatement depends on the surface. Soil and basic paving are different from decorative stone, resin drives or internal floors. The work scope should state what will be lifted and how it will be made good.

A simple, evidence-led process

Locate and plan

Survey findings and pipe tracing reduce the amount of ground that must be opened.

Excavate safely

The work area is protected and the damaged pipe is exposed with care around other services.

Replace and reinstate

New pipework is tested before the trench and surface are restored as agreed.

Frequently asked questions

Do all collapsed drains need excavation?

A fully crushed pipe normally does. Minor deformation may have other options, but CCTV evidence is needed.

How do you find the right place to dig?

Camera distance readings and tracing equipment can locate the damaged section from above ground.

Will the surface be put back?

Reinstatement should be agreed before work starts, including any limits where exact material matches are not possible.
