Understanding CCTV Drain Surveys: Why It’s Crucial & How Aquablast Does It Right
If you’ve ever had persistent drainage problems — recurring blockages, mysterious leaks, or slow drainage — standard cleaning may not be enough. You could be chasing symptoms, not causes. To truly understand what’s happening underground, you need clear visual insight: that’s where a CCTV drain survey comes in. In this article, we’ll explain why such surveys meet the gold standard of diagnostics — and how Aquablast Drain Services Ltd performs them expertly for property owners in Weston‑super‑Mare, Bristol, Taunton, and across the South West.

1. Why CCTV Drain Surveys Are Essential
Imagine diagnosing a problem behind a wall without looking inside — you might guess wrong. The same applies to drains buried under ground or under your building. CCTV (Closed-Circuit Television) surveys let engineers see the exact condition of drains internally. This avoids guesswork, unnecessary digging, and wasted cost.
Without a survey, you risk:
Misdiagnosing: treating a blockage when the real issue is a crack
Overperforming: doing large excavation when a minor relining would suffice
Recurrence: not addressing root causes so problems come back
With a CCTV inspection, engineers can locate precise fault zones, inspect damage, and plan tailored repairs.
2. What Is a CCTV Drain Survey?
Here’s what happens in a typical CCTV drain inspection:
A small, waterproof camera is mounted on a flexible rod or crawler.
Engineers insert the camera via an access point (manhole, cleaning eye, inspection chamber).
The camera is pushed along the pipe, streaming real-time video and images to a monitor.
It records continuous footage and still images.
In more advanced systems, the camera can include sonde (a locator device) to map position above ground.
The surveyor moves the camera slowly, pausing at joints, bends, or suspicious areas.
This gives a full visual map of the internal state of the drain from start to finish.
3. Benefits of CCTV Survey: Why It’s Worth It
Using CCTV inspection brings many concrete benefits:
Accurate diagnosis — you see exactly where cracks, leaks or blockages are
Cost savings — you avoid blind digging or over-engineered solutions
Targeted repair — you fix the damaged segment rather than the entire run
Better documentation — video provides evidence and helps with insurance or planning
Preventive insight — early signs of wear or root encroachment can be caught before failure
In short, CCTV surveys reduce risk, waste, and uncertainty.
4. When Should You Ask for a CCTV Survey?
Here are scenarios where a CCTV check is strongly recommended:
Problems keep returning after repeated unblocking
There’s been subsidence, ground movement, or new cracks in property
Pipe runs cross under buildings, driveways or garden areas where excavation is costly
You’re buying or selling property and need condition assurance
Upgrades or structural changes are planned and you need to know pipe alignment
You suspect root intrusion, misalignment, offsets, or pipe collapse
In these cases, CCTV gives you clarity and confidence before committing to repair work.
5. How Aquablast Conducts CCTV Drain Surveys
As a local, established drainage company in the South West, Aquablast brings region-specific expertise to their CCTV work. Here’s how they typically do it:
Preliminary discussion & access checkBefore inserting the camera, they confirm access points, clean them if necessary (remove residual blockages) so the camera can pass smoothly.
Insertion & mappingThey use suitable camera rigs (crawler or push rod), calibrated for the pipe diameter, with sonde tracking if needed to know above-ground position. This helps to map the run.
Detailed inspection & annotationAs the camera moves, they note and pause at joints, tees, bends, and suspicious areas. They capture video and stills, often annotating distance from entry point or landmark.
Real-time review & client engagementThe engineer often shows you video on-site, explaining what’s wrong in plain English.
Report & recommended planAfter the survey, Aquablast produces a recorded video file, annotated photographs, a summary report (including defect locations), and suggests repairs with costs.
Because they operate locally (Weston, Bristol, Taunton), their engineers bring knowledge of typical pipe materials and root patterns in the area, aiding a more insightful diagnosis.
6. What They Look for: Common Defects & Issues
During a CCTV survey, experts seek out various common problem types, such as:
Cracks or fractures in pipe walls — often due to ground movement or aging material
Joint displacement or misalignment — the pipe may shift at joints, especially under pressure
Blockages or partial obstructions — grease, silt, debris, collapsed sections
Root intrusion — tree roots penetrating through joints or cracks
Corrosion or erosion — especially in metal or older pipes
Collapsed or deformed pipe sections — where pipes have partially collapsed
Offsets or step changes — where pipe level shifts, causing flow issues
Mineral scaling — build-up on internal surfaces, reducing diameter
Spotting these early means you can repair just those sections instead of wholesale replacement.
7. From Survey to Repair: How It Guides the Plan
Once defects are identified, the survey report becomes the roadmap. Some common repair paths:
Relining — insert a resin-saturated liner to rehabilitate damaged section without digging
Partial excavation / local dig-ups — if the damage is too severe, remove that section and replace
Root cutting and chemical treatment — if roots are detected, cut and treat to prevent regrowth
Joint realignment or sealing — fix offsets or gaps
Complete pipe replacement — in worst cases of collapse or extensive damage
Because the survey gives exact location and nature of the defects, the repair is targeted, quicker, and more cost-effective. You won’t pay for needless digging along the entire run.
8. What Customers Should Ask / Expect
As a homeowner or business, here’s what you should ask or expect from a professional CCTV drain survey:
Access & preparation — should they clean blockage first so the camera can pass
Type of camera / tracking — is it sonde-equipped so they can map above-ground
Live viewing — can you see the footage on site
Recordings & report — a digital video file, annotated photos, a defect summary
Cost transparency — a clear quote for the survey itself plus repair options
Guarantees or warranty — does the company offer follow-up guarantees on repairs
Clear explanation — in plain English: what are defects, severity, and options
Minimal disruption — methods that avoid major digging if possible
A good contractor will respect these expectations and keep you informed at every step.
9. Challenges & Limitations to Be Aware Of
CCTV surveys are powerful, but not always flawless:
Extremely blocked or collapsed pipes may prevent the camera from passing
Sharp bends or highly irregular pipes limit visibility
Lighting reflections or sediment may obscure detail
In complex junctions or multiple fittings, depth perception can mislead
The camera is one piece — some small cracks or leaks between joints may be undetected
Yet even with these limitations, CCTV gives far more insight than guessing or blind digging.
