Why is a CCTV Drain Survey needed?

Drains, by their very nature of being underground, are subjected to a number of stresses over the years.  The ground can move dramatically, depending on how wet or dry it is, shrub or tree roots grow around the pipes and subsidence can also add high additional weight over the pipes. In order to check drains and pipes periodically a CCTV Drain Survey can be carried out.

Traditional Salt Glazed sewer pipes will start to breakdown after a while and these stresses can start to cause leaking at the joints, cracking along the pipes or at worst complete collapse. Leaky soil pipes are not only a potential health hazard but can also wash away the foundations of a property causing subsidence. Damaged pipes can cause blockages.

When buying a property, the mortgage lender will often want assurance that the pipes are in good order. How can this be done, without having to expose the pipes? A Close Circuit Television (CCTV) drain survey is ideal for this purpose. This is a totally non-invasive process in which we insert a ‘rod’ with a camera attached at one end, connected to a monitor and recording system at the other end. If a problem is detected, an on-screen meter counter can determine the exact position.

 

If a drain repair or patch to the pipe is necessary, there are a number of options available, including replacing the broken section by excavation, or alternatively and in most cases preferable by no-dig or trenchless technology which involves relining the drain or pipe from within with a Glass reinforced plastic. This is particularly useful where pipes are inaccessible, such as under buildings.

After a drain repair has been carried out a further CCTV drain survey will need to be carried out check to make sure that water is free flowing without any restrictions.
