Blocked or damaged drains rarely fail all at once they leave clues: slow sinks, gurgling pipes, unpleasant smells, or repeat call-outs after rodding. Whether you are dealing with a recurring blockage or want peace of mind before purchasing a property, Cargate Engineering Ltd provides expert CCTV drain surveys.

Our drain camera inspections utilise cutting-edge, remote-controlled technology, allowing us to thoroughly inspect the inside of your drains and sewers without the need for costly excavation or disrupting your business or home. A professional CCTV drain survey gives you answers quickly, without excavation, helping you locate drain blockages without digging and plan the right fix the first time.

Advanced Drain Camera Survey Technology

Cargate Engineering Ltd offers one of the most sophisticated drainage surveying services on the market. A drain camera is a high-resolution, waterproof camera – using advanced, remote-controlled, wheel-mounted camera units, we capture HD-quality images of pipes of all sizes.

This allows us to identify issues quickly and efficiently, often in a single pass, with no need for further intrusive diagnostics.

What Does a Drain Survey Show?

People often ask what does a drain survey show beyond “there’s a blockage”. Our high-resolution cameras provide clear, detailed images. A proper drainage survey can reveal:

Grease, fat, scale, wipes and silt build-up (partial or full obstruction).
Misaligned joints, fractures, deformation, or collapse.
Poor installation (backfalls, bellies, incorrect connections).
Hidden manholes and unknown runs (useful for extensions).
Tree root intrusion into drains and exactly where roots are entering.
Evidence of vermin access routes or damaged interceptors.

How Our London CCTV Drain Surveys Work

Here’s how a CCTV drain survey works during a typical London visit:

Site check & access: The engineer identifies the best entry point and confirms water flow conditions.
Camera insertion: The drain camera is introduced and progressed through the line.
Live diagnosis: Blockages, defects, and connection issues are identified in real time.
Drain mapping and tracing: If needed, a sonde/locator tracks the camera head to plot route and depth.
Seamless Process & Online Portal: All footage is recorded electronically and securely uploaded to our online portal for easy access.
Report & recommendations: You will receive a comprehensive technical report explaining all findings. This includes a formal pre-purchase drain survey report if required for conveyancing or negotiation.

Commercial CCTV Drain Surveys

For many commercial properties, such as bridges, office buildings, and industrial structures, checking for drainage problems can be a daunting task. Because complex internal vertical and horizontal drainage systems are hidden from view, issues can go unnoticed until it is too late.

Whether you need pre-planned commercial maintenance or an emergency drain blockage diagnosis, our remote-controlled systems easily manoeuvre through drains of any shape or size. We provide real-time footage to save your business time, money, and disruption.

Comprehensive Solutions: CCTV & High-Pressure Jetting

Once we diagnose the issue, we can often resolve it immediately. After the survey, we will walk you through the footage and recommend effective solutions, such as high-pressure jetting or no-dig pipe relining for any identified cracks, preventing further damage.
