What is a 3D CCTV Drain Survey?
3D scanning technology allows drain engineers to accurately map to within 1cm the location and dimensions of drain inspection chambers, as well as how high above sea level they are. Much like CCTV drain inspections, specialist cameras are used to examine drains and sewer pipes for drain mapping, subsidence reports, and to complete pre-build and pre-purchase surveys. However, 3D CCTV gives a greater understanding and level of detail with the use of precise cameras.
