What Are Commercial CCTV Drainage Surveys?
A CCTV drainage survey uses specialist high-definition camera equipment to inspect underground drainage systems without excavation. It provides a clear assessment of pipe condition, identifies defects and helps property owners, developers and engineers make informed decisions. Survey X carries out CCTV drainage surveys across the UK using professional crawler and push-rod camera systems. Every survey is supported by a detailed engineering report containing photographs, defect coding, condition assessments and practical repair recommendations.
Typical defects identified include:
- Structural cracks and fractures
- Displaced joints
- Pipe deformation
- Infiltration and water ingress
- Root ingress
- Blockages and debris
- Collapsed drains
- Connection and construction defects
How Our CCTV Drainage Survey Process Works
Every Survey X CCTV drainage survey follows a structured inspection process to deliver accurate, reliable information on the condition of your underground drainage system.
Our engineers begin by assessing the drainage network and identifying the most suitable access points. Where necessary, the pipework is cleaned using high-pressure water jetting to remove silt, debris and obstructions that could affect the survey.
A high-definition self-propelled CCTV crawler or push-rod camera is then introduced into the drainage system. As the camera progresses through the pipework, live video footage is recorded while defects, connections and construction details are logged in real time.
All observations are assessed using recognised industry coding standards before being compiled into a professional Survey X consultancy report. Each report includes annotated photographs, defect locations, condition assessments and practical engineering recommendations to support maintenance planning, property transactions, insurance claims or future development.
1
Site Assessment
We review the drainage layout and identify suitable access points before beginning the survey.
2
Drain Cleaning
Where required, jetting removes debris and silt to ensure clear camera visibility.
3
CCTV Inspection
High-definition cameras inspect every section of the drainage network.
4
Defect Recording
Structural defects, root ingress, displaced joints and blockages are accurately recorded.
5
Consultancy Reporting
Every observation is professionally assessed and presented with photographs and recommendations.
6
Remedial Advice
We provide clear engineering recommendations to help clients prioritise repairs and maintenance.
Common Drainage Defects Identified During CCTV Surveys
Collapsed Drains
Major structural failure requiring repair or replacement.
Root Intrusion
Root ingress can develop where tree and shrub roots enter damaged joints or cracks in underground drains. Roots may trap debris, reduce the available pipe diameter and contribute to recurring blockages. A CCTV drainage survey records the visible location and extent of root intrusion, helping assess whether root cutting, local repair or drain lining should be considered. The condition of the pipe must be assessed before selecting a repair.
Displaced Joints
Displaced or open joints occur where adjoining pipe sections no longer meet correctly. They can create ledges that catch debris, allow root ingress or provide a path for groundwater infiltration and leakage. A CCTV drainage survey identifies visible joint defects and records their position along the surveyed run. This information supports targeted repair planning and helps distinguish isolated defects from more widespread movement in the drainage network.
Infiltration
Groundwater entering defective drainage systems.
Cracked Pipes
Cracks and fractures can affect the structural condition of a drainage pipe and may allow water to escape or enter the system. CCTV drain inspections record visible cracking, its position and any associated deformation or debris. Survey findings help prioritise further investigation and repairs, with options such as a local patch, lining or replacement assessed against the pipe condition, access and project requirements.
Blockages
Silt, grease, wipes and other debris can reduce drainage capacity and cause slow flow, recurring blockages or backing-up of the system. A drain camera survey helps identify the visible obstruction and any underlying pipe defects contributing to the problem. Where deposits prevent a clear inspection, cleansing may be required before a follow-up survey. Findings help target maintenance and assess whether cleaning alone is sufficient or repairs need consideration.
