Step 1: Choose Your Service
Primary Focus:You need this service if an underground drain pipe has caved in, ground is sinking above the pipe route, or a camera lens hits a wall of broken clay masonry.
Alternative Services:If the pipe wall has cracks or minor root ingress but still holds its round shape, we can repair it without digging using our No-Dig Drain Relining service.
Fast Diagnostics & Structural Pipe Reconstruction
A collapsed drain happens when underground pipe walls cave in, break, or crush. Sewage cannot flow past the broken section, and leaking wastewater slowly washes away surrounding soil, causing paving and garden lawns to sink.
We respond 24 hours a day to locate the collapse. Our engineers send a waterproof camera and radio sonde down the line. We pinpoint the exact surface location and depth of the damage before recommending a repair.
If the pipe still holds its shape, we can reline it without digging. If the pipe has caved in completely, we execute a clean, targeted excavation to replace the broken section with modern PVC pipework.

- Stop using sinks, showers, and toilets immediately to stop wastewater spilling into sunken ground.
- Do not walk on or park heavy vehicles over sunken paving or dipping lawns above the drain line.
- Keep children and pets away from wet or sunken soil areas.

Warning Signs Your Drain Has Collapsed
Look out for these severe warning signs that point to structural pipe failure.
Dips or sinkholes forming directly above your underground drain line mean soil is washing into a broken pipe.
If wastewater backs up again right after an engineer rods or jets the drain, broken pipe masonry is blocking the flow.
Damp, pungent sewage odours that return straight away near your home point to wastewater escaping into surrounding soil.
Our HD camera hits a solid wall of broken clay, crushed pitch fibre, or collapsed soil.
Toilets, ground-floor showers, and outdoor gullies backing up simultaneously when water runs.
Patches of soggy, lush grass or wet soil above your drain line during dry weather.
