What will a CCTV drain survey show?
A CCTV drain survey in Portsmouth can reveal many situations which, if left unaddressed, may lead to serious situations which could harm the general public or be very costly to repair. Such situations may be:
Damaged pipes: construction work close to your drainage system could lead to damaged pipes due to the weight and impact of construction vehicles overhead. The damage could appear minimal at the time but even the smallest crack will grow under pressure and as water leaks out the drainage system will weaken.
DIY waste: any DIY building work can lead to debris building up in the drain pipes as often people wash out tools and builder’s buckets in the sink or under the outside tap which leads into the drainage system. Cement, plaster, and grouting can stick to the inner walls of the pipe and set solid. As other debris feeds into the system it can get caught in this build-up and cause a drain blockage.
Tree roots: roots are constantly searching for water and can 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. Damage may start as a small hairline crack, but as water begins to leak out this crack will widen and may cause the drainage pipe to collapse.
Vermin: open drains offer a convenient 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 building 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.
