CCTV Drainage Survey

What’s in a CCTV drainage survey?

Our dedicated teams are ready to perform a detailed CCTV drainage survey, providing you with an in-depth visual inspection and a comprehensive condition report, along with valuable survey data.

Using innovative remote visual inspection (RVI) technology, our CCTV surveys for drains offer you high-definition imagery of subterranean conditions—whether underground, underwater, or within pipework, voids, and confined spaces.

Our thorough drain survey process includes the manual lifting of every inspection chamber or manhole cover, with our experts finding the chambers as needed. We accurately document the invert depth, measure the pipe diameter, checking the lining of the drain, and assess the type of drainage system, including the construction of each chamber. All findings are then overlaid onto the topographical survey of your site, ensuring all risks are clearly shown and categorized.

Choosing a drain contractor

We’re the leading UK engineering surveyor, and offer a full in-house service. We provide you with accurate, detailed report data allowing you to make informed choices. Typically, we conduct the CCTV drainage survey in conjunction with underground utility surveys and topographical assessments, or we can use existing site surveys for your convenience.

Why do building drains need CCTV drainage inspection?

Our clients opt for a full-length CCTV drainage survey to mitigate potential issues as early into the project as possible, including leak detection underground. This includes the specific condition of each pipe and identifying any structural defects, root ingress, cracks, and blockages. Should our technical report highlight any significant issues, such as blockages, our team will conduct sewer maintenance with high-pressure jetting to the areas of concern to restore the entire drainage network to its fully functioning capacity.

Sewer Maintenance

We advise on sewer maintenance plans for a multitude of location types, helping identify and resolve drain unblocking in public buildings, educational facilities, country estates and listed buildings. We also deal with outdoor spaces areas of public footfall including car parks.

In the case of blocked drainage and sewer systems, our solutions for high pressure jetting include de-scaling as well as fat and grease removal. We can also use root cutting equipment within the drainage network to cut back and clear any root ingress before jetting the system completely clear.

Our ongoing drain maintenance programmes can be useful in locations known for localised or seasonal flooding to prevent sewer systems from overflowing. Where our CCTV drainage survey has identified blockages or root ingress our team will advise on the best action for optimal Sewer maintenance, from high-pressure jetting or remediation measures.

What’s the difference between sewer cleaning and drain cleaning?

Drains are connected to a building’s sink and toilets, which can become blocked through debris build-up or inappropriate use, such as nappies being flushed. Usually there are multiple drains on site, and if these are slow draining but functional, your blockage may actually be in the sewer system. Our team can identify the problem and bring a range of solutions that include high pressure jetting, de-scaling, and fat and grease removal. For root ingress we employ root cutting equipment within the drainage network to cut back and clear before jetting the system completely clear.
