London Drainage Facilities conduct CCTV surveys and SONDE + locating to investigate the cause of blockages so that action can be taken to avoid repeated problems.
When you request a CCTV drain survey in London, you will receive the full report on DVD, along with a comprehensive written document and indicative site plan which is produced using Wincan reporting software. If the drainage CCTV survey shows defects, still images will be taken and an estimate prepared to resolve the problem.
Nature of Problem
You may just be facing a general maintenance issue where drainage hasn’t been cleaned or regularly serviced. Scale and silt deposits form, which require a straight forward cleaning by either high pressure water jetting and/or heavy duty electro-mechanical machining.
However, if your drain survey shows us that the cause of problem is more extensive, like a collapsed drain, we generate a full written report, utilising insurance approved reporting software. This is accompanied by a full video analysis and site plan together with photos of the exact defect and supported by the costs involved in carrying out the required repairs.
Latest Technology including Crawler Units
With the latest drain surveying technology, our specialists are now able to traverse around toilet pans, trapped gullies and numerous 45 degree bends. In addition, we now provide Crawler Units to survey large diameter pipework up to 900mm so no job is too big for us to carry out. In the event that major structural defects are discovered, one of LDF’s technical team will evaluate the video footage and decide on the most suitable and cost effective repair solution available.
WHO WE COVER
Whether your planning a regional programme of work, or require urgent help with an unexpected issue, you need a partner who can respond quickly and efficiently.
Solution(s) and Service
Repairs can range from conventional excavation, insitu-structural lining works and/or point patch repairs. If problems are noted as tree root infiltration, water driven root cutting heads can be used to gently trim back surplus roots, sufficient enough so that lining procedures can be implemented to prevent any future growth.

What is a CCTV survey?
A CCTV survey is a process of examining the condition of drainage systems remotely with a camera system that records video footage and captures other useful data. Our CCTV drain surveys help to survey an area and enable us to locate any problems and remove any blockages swiftly and effectively.
Once we have completed a CCTV drain survey, we will provide you with the full report on DVD, along with a comprehensive written document and a site plan. We can also use the technology to show defects of a drainage system, where we take still images and provide an estimate on how to resolve the problem.
