Highways CCTV drain surveys help identify hidden drainage defects beneath roads, gullies and infrastructure before repairs begin.
AJS Environmental provides professional highways CCTV drain surveys for roads, commercial estates, public sector sites and infrastructure drainage networks across Essex, London, Kent and Hertfordshire.
Highways drainage problems are not always visible from the surface. A blocked gully, standing water, recurring flooding or collapsed pipe may require internal CCTV inspection before the correct repair method can be confirmed.
This guide explains how highways CCTV drain surveys work, what they can identify and how survey evidence supports Find and Fix highways drainage repairs, patch lining, UV drain lining and highways jet vac services.
Quick Answer:
A highways CCTV drain survey uses specialist camera equipment to inspect underground drainage systems connected to roads, gullies, chambers and infrastructure assets. It helps identify blockages, cracks, root ingress, silt build-up, displaced joints and repair requirements without unnecessary excavation.

What Is a Highways CCTV Drain Survey?
A highways CCTV drain survey is an internal camera inspection of drainage systems serving roads, highways, gullies, chambers, commercial sites and public infrastructure.
The camera is inserted into the drainage system to record pipe condition, identify visible defects and help confirm the most suitable repair or maintenance approach.
Common reasons for a highways CCTV survey include:
- Recurring surface water issues
- Blocked or slow-draining gullies
- Suspected pipe collapse or deformation
- Root ingress affecting pipe flow
- Evidence required before repair approval
- Pre-repair inspection for patch lining or UV lining
Important:
A CCTV drain survey should usually be completed before structural repair work begins. It helps confirm the defect type, location and severity so the repair method is based on evidence rather than guesswork.
What Can a Highways CCTV Survey Identify?
Highways drainage systems can fail for many different reasons. CCTV surveys help locate and record the issue before the site team decides whether cleaning, jetting, lining or excavation is required.
A survey can identify:
- Root ingress entering through joints or damaged sections
- Cracked or fractured pipes affecting structural integrity
- Displaced joints causing leakage or infiltration
- Silt and debris build-up restricting flow
- Collapsed or deformed pipework requiring repair planning
- Standing water caused by falls, obstruction or structural defects
- Defects suitable for no-dig repairs such as patch lining or UV lining
How Highways CCTV Surveys Support Find and Fix Repairs
AJS Environmental’s highways drainage work often follows a Find and Fix approach.
This means the drainage issue is first located using CCTV inspection, then the right repair method is selected based on the condition of the pipework.
| Stage | What Happens | Why It Matters |
|---|---|---|
| CCTV Survey | The drainage system is inspected internally using camera equipment. | Confirms defect location, type and severity. |
| Cleaning or Jetting | Silt, debris or obstruction may be removed to improve visibility and flow. | Prepares the pipe for accurate inspection or repair. |
| Repair Planning | The correct method is selected, such as patch lining, UV lining or jet vac support. | Avoids unnecessary excavation and reduces disruption. |
| Verification | A follow-up CCTV inspection can confirm completion and condition. | Provides evidence for sign-off and reporting. |
When Should You Arrange a Highways CCTV Drain Survey?
A CCTV survey is useful whenever there is uncertainty about the condition of underground drainage.
Common situations include:
- Repeated highway flooding
- Blocked gullies that return after cleaning
- Drainage problems on roads, car parks or commercial estates
- Before patch lining or UV lining repairs
- Before planned highways maintenance work
- When contractors need drainage evidence for reporting
- When councils or facilities teams need condition information
Simple Tip:
If the drainage problem keeps returning, do not keep treating it as a simple blockage. A CCTV survey can show whether the cause is root ingress, pipe damage, silt build-up or a structural defect.
Highways CCTV Survey Process
Our highways CCTV drain survey process is designed to identify the issue clearly and support practical next steps.
- Site review – access, safety and inspection requirements are assessed.
- CCTV inspection – camera equipment is used to inspect the drainage run internally.
- Defect identification – cracks, roots, silt, displaced joints and damage are recorded.
- Repair recommendation – suitable next steps are advised based on the findings.
- Reporting and evidence – survey information can support maintenance, repair approval and project sign-off.

What problems can a CCTV survey find?
CCTV surveys can identify root ingress, cracks, displaced joints, silt build-up, blockages, infiltration, standing water and collapsed pipe sections.
Can CCTV surveys support Find and Fix drainage repairs?
Yes. CCTV surveys are often the first stage of a Find and Fix workflow, helping locate the defect before cleaning, patch lining, UV lining or jet vac support is planned.
Can highways CCTV surveys be carried out at night?
Where suitable, highways CCTV surveys can be planned during lower-traffic or restricted-access periods to reduce disruption.
Do you provide recommendations after the survey?
Yes. AJS Environmental can provide practical recommendations based on the survey findings, including cleaning, jet vac support, patch lining, UV lining or further investigation.
