Long distance CCTV inspection for pipelines

When the problem is not where you expect

Not all pipes are short or easy to access.
In many cases — especially in underground pipes, external drains or long networks — the issue may be located far from where the symptoms appear.

Long distance CCTV inspection allows us to inspect extended sections of pipe and understand what is really happening inside, without excavation or guesswork.

Going further — with control and clarity

We use inspection systems designed for long runs, with reinforced cables and stable cameras that maintain image quality throughout the entire length.

This allows us to:

• inspect underground pipelines across their full length

• identify pipe settlement or misalignment

• detect blockages or flow issues

• pinpoint the exact location of the problem

Without this type of inspection, many interventions are based on trial and error — opening, testing and reopening — which increases cost and disruption.

What we actually see on site

In underground networks — especially older clay (vitrified) pipes — we often find settlement, joint displacement and structural defects.

These issues may not be immediately visible but can lead to:

• recurring blockages

• loss of watertightness

• soil infiltration around the pipe

Long distance inspection helps detect these issues early — or confirm exactly where failure has already occurred.

Where this type of inspection is most useful

This approach is particularly relevant for:

• external drainage systems in houses and buildings

• connections between inspection chambers

• underground sewer or rainwater pipelines

• situations where the source of the problem is unclear

Diagnosis first, intervention after

The principle is simple: understand first, act after.

Long distance CCTV inspection allows decisions based on real data, avoiding unnecessary excavation and helping define whether the solution should be local or more extensive.

That is what makes the difference between a controlled intervention and an ongoing problem.
