With the continual increase in the population of London, drains are finding it difficult to cope with the waste which is being disposed. The old drainage systems are getting damaged by tree branches and other types of debris, this results in the whole drainage system being over used. Maintenance and checking of these drainage systems is very important so we can all lead healthy lives.

What do CCTV drain surveys do?

There are many reasons why blockages such as waste accumulation, ground movement, corrosion, and tree root penetration cause drain problems. The need for conducting a CCTV drain survey by drain specialists arises in this scenario. This survey will help you to know the root cause of the problem and after the problem is found, the drainage specialists will be able to offer an effective solution.

It is very difficult to get into the drain and check the problem. So new equipment helps to view and repair the blocked drains. The new CCTV drain surveys are done with the help of small units that allow specialists to view the problem on monitors.

After receiving the data from the CCTV drain survey, they will know where the blockage lies and accordingly will use techniques and equipment to unblock the drain.

The techniques used in clearing drain blocks

Drain Rodding – This is a simple technique; the blockage or waste is pushed through by using steel rods and this allows the system to function properly.

High Pressure Water Jetting – This technique is used to strip away deposits stuck to pipe walls, allowing it to flow freely.

Electro-mechanical Cleaning – This technique helps to wash out the waste pipes and sewers. Steel cables are fitted with sharp blades that cut through waste and tree roots to restore the pipe to a as new condition.

If the drainage system is damaged beyond repair, drain re-lining can still solve your drainage problems.
