Excavation & Drain Replacement

Collapsed Drain Repair & Replacement in Eastbourne

When a drain has collapsed or is too badly damaged to reline, it needs digging out and replacing. We excavate, replace and reinstate damaged drains for homes, businesses and commercial sites across Eastbourne and East Sussex, from a single broken section to a complete new drain run.

Warning Signs

Signs of a Collapsed or Broken Drain

A collapsed drain doesn't always announce itself straight away.

Look out for the signs below. If you notice any of them, a CCTV drain survey will confirm where the damage is and how bad it is, before any digging starts.

  • Drains that block again soon after being cleared
  • Water draining very slowly from sinks, baths and toilets
  • Sewage smells around the property or in the garden
  • Dips, sinking ground or potholes above the drain line
  • Damp patches on walls or floors near a drain
  • Rats or other pests appearing around the property
  • A CCTV survey showing a collapsed or deformed pipe

What Causes It

Why Drains Collapse

Most collapsed drains we find in East Sussex come down to one or more of these:

  • Age: older clay and pitch fibre pipes become brittle or lose their shape over time
  • Tree roots forcing joints apart and breaking the pipe
  • Ground movement and subsidence, especially in clay soils
  • Heavy vehicles driving over shallow drains
  • Poor installation, such as pipes laid without proper bedding or falls
  • Earlier repairs or building work that disturbed the pipe

Reline or Replace?

When Excavation Is the Right Repair

Where a pipe is cracked but still holding its shape, no-dig relining is usually quicker and less disruptive. But relining needs something to line. If a section has collapsed, is badly misaligned, has sunk so water sits in it, or the pipe is the wrong size or in the wrong place, excavation and replacement is the only lasting fix.

Often the answer is a mix: we dig out and replace the collapsed section, and reline the rest of the run. We'll show you the survey footage and explain the options before any work is agreed.

How It Works

How We Replace a Collapsed Drain

1. Survey and Locate

We CCTV survey the drain to find the exact position and depth of the damage, so we only dig where we need to.

2. Plan and Make Safe

We check for buried cables and pipes, set up a safe work area and agree access, parking and any permissions needed.

3. Excavate and Replace

We dig down to the damaged section, support the excavation where needed, remove the broken pipe and lay new pipework.

4. Test and Reinstate

We test and camera-check the new section, backfill the excavation and reinstate the surface.

New Drainage

New Drain Runs and Drainage Installation

Sometimes the best option is a new drain altogether. We install new drain runs, replace old inspection chambers, add new connections for extensions and outbuildings, and re-route drains that are in the way of building work. New pipework is laid to the correct falls and bedded properly, so it drains well and lasts.

After the Dig

Leaving Your Property as We Found It

We know a trench through a drive or garden is the last thing anyone wants. We keep the excavation as small as the job allows, protect surrounding areas while we work, and backfill and reinstate the ground when the new pipe is in. We'll agree how the surface will be finished, whether that's soil and turf, concrete or another surface, before work starts.
