How do you avoid underground gas or electric cables when digging?

We scan the area with professional CAT cable locators before digging to pinpoint buried utility lines safely.

What happens to my lawn or driveway paving during excavation?

We carefully lift block paving slabs or lawn turf before digging. Once the pipe is replaced, we backfill, compact the ground, and restore your surface.

How much does a targeted drain excavation cost?

Targeted pipe replacement excavations typically range from £850 to £2,200 depending on depth, location, and pipe length. We agree all prices upfront.

What guarantee do I get on new PVC pipe installations?

All new PVC pipe replacement and structural ground repairs come with our written 5-Year Guarantee.

Drain Excavation & New PVC Pipework Replacement

Q: Why would a drain need excavation instead of no-dig relining?

Excavation is required when a pipe has completely collapsed, crushed flat, or has a bad slope where water runs uphill.

Underground pipe crushed flat, back-pitched, or severely collapsed? When no-dig relining is not possible, targeted open-trench excavation replaces the broken pipe section with heavy-duty PVC. Call 0800 088 4258 for an expert site assessment.

Is Drain Excavation Required?

Primary Focus:Excavation is necessary when an underground pipe has completely collapsed, crushed flat, or has a bad slope so water runs uphill.

Alternative Services:If your pipe wall holds its round shape and only has cracks or root gaps, we can fix it without digging using our No-Dig Drain Relining service.

Service Overview

Targeted Underground Pipe Replacement

While no-dig relining is our preferred method whenever possible, open-trench excavation is necessary when an underground drain is crushed flat or heavily sagging.

We run CAT utility scans before digging to map buried electric, gas, and water cables safely. We carefully lift paving slabs or lawn turf, dig down to the broken pipe, and replace it with heavy-duty PVC pipework laid at the correct slope.

We backfill and compact the trench in layers, reinstate your driveway or garden surface cleanly, and issue your written 5-Year Guarantee.

When You Need Open-Trench Drain Excavation

Surgical ground replacement for severely damaged pipe runs.

Completely Collapsed Clay or Pitch Fibre Pipes

When pipe walls cave in completely, resin liners cannot pass through and physical replacement is required.

Sagging Pipes Running Uphill

Pipes that have settled sagging downwards need digging out to reset correct gravity fall gradients.

Installing New Manhole Inspection Chambers

Adding new access manholes or gully traps requires targeted excavation to tie into main pipe runs.

Redirecting Drains Around Home Extensions

Rerouting pipework around new building footings or conservatory foundations.

Our Excavation Capabilities

Complete ground engineering for domestic and commercial properties.

Precision CAT Utility Location Equipment

Professional cable locators preventing accidental damage to gas, water, or electric lines.

Heavy-Duty PVC Drainage Pipework

Thick-walled plastic drainage pipework laid on pea-shingle aggregate bedding.

Surface Reinstatement

Backfilling, layer compaction, and neat reinstatement of soil, lawn turf, or block paving.

Important Things to Know

We scan all excavation sites for underground utility cables before digging commences.
Reinstated lawn turf or paving may require settling time after heavy soil compaction.
All new pipe installations strictly comply with UK Building Regulations Approved Document H.
