Drain Excavation across Stockport

Drain excavation is the definitive repair method for severely damaged drains. Relining or patch repair cannot fix these. Some pipes have collapsed or lost their shape. Others have damage along a long length. In these cases, excavation lets us remove the failed section and replace it with new pipework.

Our excavation teams use mini-diggers, hand-dig tools and shoring systems. These suit the depth and ground conditions. We work in all soil types found across Stockport and Cheshire, including clay, sand, rock and mixed ground. Before we dig, we use CCTV survey data to plan the work, because it shows the exact location and extent of the damage. So we dig only where necessary and keep disruption low.

We install new pipework to current building regulations. We use suitable materials and the right gradient. Once we lay and test the pipe, we backfill the trench in compacted layers. Then we reinstate the surface to match the area around it, whether that is lawn, paving, tarmac or concrete. Drain excavation typically takes one to three days, depending on pipe length, depth and the surface work.

Signs you need drain excavation help

✓ A CCTV survey has confirmed a complete pipe collapse or loss of pipe shape that cannot be relined
✓ There is visible subsidence or a sinkhole forming above a drainage route in your garden or driveway
✓ Sewage is leaking into the surrounding ground, causing contamination or persistent damp
✓ Previous relining or patch repairs have failed because the underlying pipe structure is too degraded
✓ You need to replace a section of pipe to accommodate a new connection for an extension or development

Our process

1.
Survey and Plan
We review the CCTV footage to plan the dig. We mark out the dig area, confirm pipe depth and look for utilities or obstacles. You receive a clear scope of work before we start.
2.
Excavation
We carefully dig down to the damaged pipe. We use a mini-digger in open areas and hand-dig in tight spaces or near buildings. We install shoring as needed for safety.
3.
Pipe Replacement
We remove the damaged section. We replace it with new pipework laid to the correct gradient. We connect it to the existing pipes upstream and downstream with suitable adaptors and sealed joints.
4.
Backfill and Reinstatement
We backfill the trench in compacted layers to prevent future settlement. Then we reinstate the surface to match the area around it, whether turf, paving, concrete or tarmac. We leave a neat, professional finish.

Drain Excavation — frequently asked questions

How long does drain excavation take?

A straightforward dig on a short section at moderate depth typically takes one day. However, longer runs, deeper pipes or hard ground may take two to three days. We always give a realistic timeframe before starting.

Will excavation damage my garden or driveway?

Excavation does need a trench to reach the pipe. Because we use precise CCTV data, we keep the trench narrow and short. We also reinstate all surfaces to match the surrounding area once the new pipe is in. Most gardens and driveways look fully restored within a few weeks.

Is excavation the only option for a collapsed drain?

If the pipe has collapsed completely and lost its shape, excavation is usually the only reliable repair. We may sometimes reline partly collapsed pipes, although this depends on the damage. A CCTV survey shows which method suits your situation.
