Because drains are largely hidden from view, the exact cause and nature of the problem may not be apparent. That's why a cctv survey or inspection and diagnosis are crucial features.

Over time and usage, drains and sewers can deteriorate. It may take several years, but drains can suffer as a result of many factors such as ground movement, poor construction, tree root invasion etc. A CCTV survey is specifically designed to investigate a drain's condition.

When problems with drainage or pipework are to be avoided at all costs, CCTV enables potential faults to be identified before they become a problem.
