What will a CCTV Drain Survey Reveal?
A CCTV drain survey can reveal many situations which, if left unaddressed, may lead to serious situations which could be harmful or very costly to repair. Such situations may be:
Damaged pipes: construction work carried out close to underground pipework could damage pipes due to the weight and impact of construction vehicles overhead. However careful workers are, accidents do happen. Sometimes the damage caused is not noted at the time, but a small crack in the structure will grow under pressure and over time. This could lead to anything from a slow leak into the surrounding subsoil, weakening the structures above, to a collapse in the pipe itself. Such damage could go unnoticed for many months or even years up until the point where it has gone beyond being a simple repair and has become a major issue.
Tree roots: if you’ve ever seen a building that has been left for any length of time, you’ll understand just how invasive tree roots can become. In their search for water, they will break through concrete structures and disintegrate brickwork. Concrete, clay, and even plastic pipes don’t stand a chance and can be easily invaded by these roots and may at first suffer just a small hairline crack from which water leaks slowly, and as time passes, these cracks will widen and may cause the drainage pipe to collapse.
Vermin: open drains offer a cozy home to all kinds of wildlife, from stray dogs and foxes to field mice and, more often than not, families of rats. This vermin brings food into the drains, builds nests, and breeds. All this can lead to debris build up in the pipework, contamination, and rats, in particular, entering into buildings through the drains, carrying with them the risk of them chewing through electrical wiring and insulation materials or bringing a disease such as salmonella–these are things we all want to avoid.
