Excavation of a collapsed drain pipe by professional drainage engineers

Collapsed Drain Scenarios

Collapsed drains under different parts of your property — what to expect and how we fix them.

Collapsed Drain Under Driveway

A collapsed drain under a driveway is a common but serious problem. The weight of vehicles combined with ground movement can crack and collapse drainage pipes, leading to sinkholes, driveway subsidence, and sewage issues. Our team specialises in driveway drain repairs with minimal disruption.

Collapsed Drain Under House

A collapsed drain running beneath your house is one of the most challenging drainage repairs. These pipes are difficult to access, and a collapse can cause serious structural issues including subsidence, damp, and persistent foul odours inside the property.

Collapsed Drain Under Patio

Drains running beneath patios are susceptible to collapse from ground movement, tree root damage, and the weight of heavy paving. A collapse can cause patio slabs to sink, crack, or become unstable, and may allow sewage to leak into the surrounding ground.

Collapsed Drain Under Road

A collapsed drain beneath a public or private road requires specialist handling including traffic management, council permits, and careful excavation. Our team has extensive experience working on road drainage repairs, liaising with highways authorities and utility companies.

Collapsed Drain Under Garden

Garden drain collapses are often caused by tree root damage, ground movement, or ageing clay pipes. They can create sinkholes, waterlogged areas, and persistent foul smells. The good news is that garden drains are usually the most accessible and straightforward to repair.

Collapsed Drain Under Extension

Extensions built over existing drain runs are a common source of collapsed drain problems. The weight of the new structure, foundation work, and changes to ground conditions can damage pipes that were never designed to bear the load.

Collapsed Drain Under Conservatory

Conservatories are frequently built over existing drain runs, and the added weight and foundation work can damage ageing pipes. A collapsed drain under a conservatory causes damp, bad smells, and can undermine the conservatory's foundations.

Signs of a Collapsed Drain

A collapsed drain can go undetected for weeks or even months, causing increasing damage to your property. Knowing the warning signs helps you act quickly and avoid costly repairs. Here's what to look for and when to call a drainage engineer.

Bad Smells Coming From Drains

Persistent bad smells from drains are more than just unpleasant — they can indicate a serious problem with your drainage system. From broken seals to collapsed pipes, understanding the cause is the first step to fixing it.

Slow Draining Sinks and Toilets

Slow-draining fixtures are one of the earliest signs of a developing drainage problem. While sometimes caused by a simple local blockage, persistent slow drainage often points to a deeper issue in your underground pipework.

Repair Methods

Drain Relining vs Excavation

When a drain needs repairing, the two main options are no-dig relining and traditional excavation. Both are effective, but they suit different situations. Understanding the pros and cons of each helps you make an informed decision — and potentially save thousands.

How Drain Relining Works

Drain relining creates a brand-new pipe inside your existing damaged drain without any digging. A resin-saturated felt liner is inserted into the pipe, inflated against the pipe walls, and cured to form a seamless, jointless new pipe. Here's exactly how the process works.

How Long Do Drain Repairs Take?

The duration of a drain repair depends on the method used, the extent of damage, and the accessibility of the pipe. Here's a realistic guide to how long different types of drain repair take, so you can plan accordingly.

Inspection Guides

Drain Inspection

A professional drain inspection is the first step in understanding the condition of your drainage system. Whether you're investigating a problem, buying a property, or planning building work, our engineers provide thorough, detailed inspections.

CCTV Drain Inspection

CCTV drain inspection is the gold standard for diagnosing drainage problems. Our high-definition cameras travel through your pipes, providing real-time footage that reveals the exact condition of your drainage system without any need for excavation.

Drain Condition Reports

A drain condition report is a formal document detailing the state of a property's drainage system. Based on a comprehensive CCTV survey, it's used for property transactions, insurance claims, building regulation compliance, and maintenance planning.
