Structural Defect Investigations

Cracks, collapses, and displaced joints don't fix themselves, and they rarely stay the same size. A structural defect investigation tells you exactly what's wrong with a drain, how bad it is, and what needs to happen before it gets worse.

ICE Drainage carries out structural defect investigations for commercial, industrial, and domestic clients across the UK. We inspect the drain, identify and classify any structural problems, and give you a clear report to plan repairs around.

A structural defect investigation typically covers:

• A full CCTV survey of the affected drain run
• Identification of cracks, fractures, collapses, and displaced joints
• Classification of defects by severity, in line with industry standards
• The exact location and depth of each defect
• Footage and photos showing the condition of the pipe
• A written report with clear recommendations for repair

The output is designed to be usable by facilities teams, insurers, structural engineers, and contractors.

Key benefits include:

• Confirms exactly what's wrong and how serious it is
• Stops a minor defect turning into a collapse or major repair
• Gives you evidence to support insurance claims or disputes
• Helps you plan the right repair method instead of guessing
• Supports budgeting for urgent versus planned works
• Reduces the risk of subsidence, flooding, or surface damage above the pipe

If a drain has cracked, collapsed, or shifted, waiting to see what happens usually costs more than acting on it early.

Common types of structural defect

Structural problems come in different forms, and the right fix depends on which one you're dealing with:

• Fractures and cracks in the pipe wall
• Full or partial collapses
• Displaced or open joints
• Deformation, where the pipe has lost its shape under pressure
• Root ingress through cracked or open joints
• Corrosion or erosion of the pipe material
• Infiltration, where groundwater is entering through defects

Our survey identifies which of these is present and how urgent the fix is.

Our structural defect investigation process

We follow a clear process to make sure nothing gets missed.

1) Initial call and site details

We ask about the history of the problem, any visible signs above ground, and what you already know about the drain.

2) CCTV survey

We send a camera through the drain run to record its full condition and identify any structural defects.

3) Analysis and classification

We review the footage and classify each defect by type and severity, so you know what's urgent and what can be planned in.

4) Reporting

We put together a report showing what we found, where it is, and how serious it is.

5) Recommendations

We tell you what needs to happen next, whether that's excavation and replacement, lining, patch repair, or ongoing monitoring.

Common use cases

Clients often request a structural defect investigation when:

• A CCTV survey or drainage report has flagged a possible defect
• There are signs of subsidence, sinkholes, or surface depressions above a drain
• A drain has collapsed or partially collapsed
• An insurer needs evidence before agreeing to repair or replacement work
• A property is being bought, sold, or refurbished and the drain's structural condition needs confirming
