A CCTV Survey can be carried out with little fuss and disruption but they quickly establish the facts. A CCTV survey involves sending a camera down your sewer or drain and making a video recording of the results.

Reviewing the CCTV survey the drainage engineer can precisely pinpoint the problem area without the need for expensive excavations. At this point a repair plan can be established and whilst a hole might need to be dug it will be at the exact location of the problem thereby minimising subsequent costs and disruption.
