It’s really important to conduct a through survey on a drainage system before any works are carried out. The drains that leave your home may interconnect with adjacent properties, so you need to know who is responsible for which parts of the drainage system.

As well as determining who is responsible for the different parts of the drainage system, a drain survey will also be able to diagnose the exact cause of the drainage blockage. Occasionally the team of drain maintenance engineers will even use CCTV survey equipment to see inside the drain to assess the problem or any damage caused.

After drain jetting has failed, a detailed survey will allow the drainage team to make an estimated cost for repairs so the client knows how much this is likely to be, and the drainage team can factor this into their work schedule. A customer may even be able to see the images produced by the survey themselves, so they can see the extent of the damage.

CCTV surveys of the drainage system have made the lives of drain engineers in London much easier. They no longer have to rely on luck or chance to find the blockage site. They can now pinpoint the location of the drain blockage, which saves the time and money spent on unnecessary excavation.

Advances in technology have made the drain maintenance professional’s life much easier over the last few years. No longer is it necessary to excavate as soon as a drain stops working. Using high-tech CCTV imaging equipment, drain cleaning London experts can view the insides of the drain so an accurate diagnosis can be made.

Instead of excavating a drain to diagnose a problem, drain maintenance engineers can now use CCTV survey equipment to visually assess the internal workings of the drainage system. In this surveying method the drainage team insert a camera into the drainage system and then feed it along the length of the pipe towards the problem area.

CCTV imaging can help with:

Accurate diagnosis of the problem

With accurate information about the blockage, the drain maintenance team can decide what course of action to take. This may be jetting, root removal, pipe lining or excavation.

Reduce time on repairs

When a drainage problem is accurately diagnosed, the time taken for repair can be significantly reduced. This can save the drainage company time and the customer money.

Accurate positioning

If CCTV survey equipment is not used, it can be difficult to pinpoint the location of the problem. This can lead to incorrect excavation and the repair time increasing.

One of the most common blockages that drain cleaning companies in London find is caused by the infiltration of roots into the pipe network. Roots work there way into the pipe network through the small cracks in the pipe’s structure. And once they find an easy source of water they quickly multiply, blocking the drain.

Root intrusion into a drainage system couldn’t happen if the pipe was not damaged or defective in any way. The pipe needs to be in good working order and have no cracks or disturbance to work effectively all the time.

If a pipe does have cracks, not only does the chance of further damage increase, contamination from the water can enter the surrounding environment. In the worst cases, the water can wash away the soil around the pipe, which can lead to subsidence and further drainage pipe damage.

The drainage engineers in London can usually tell if root intrusion is the cause of a drainage blockage. They can insert a CCTV camera into the drain, which travels along the drain length relaying images to the engineer on the surface. The images can then be used to produce a report on the overall condition of the pipe and hence make the necessary recommendations to solve the drainage problem.

Many drainage problems can be solved quickly by knowing how to remove the blockage and by using a little elbow grease. However, when the drainage issue continues to get worse, despite your best efforts, it might be time to call in the drainage experts.

Drainage experts in London can do everything, from removing a small blockage to excavating a broken drainage pipe and instigating a pipe repair. And if your best efforts at removing the problem are coming to nothing, they will be able to help you out.

Using the very latest technology, drainage experts in London can look inside your drainage pipes and view what is actually causing the drain blockage. When the drainage experts look inside your drainage pipes, they get to see what’s happening in real time. This can be great news for drainage customers, as the time taken to diagnose a problem and rectify it has been dramatically reduced.

Due to the introduction of CCTV surveys, the likelihood for excavation has also been dramatically reduced. Where once a team of drainage engineers in London may have had to excavate a section of pipe to find out what was causing the blockage, they now only have to insert a CCTV camera into the drainage system and images are relayed to the surface which can be easily interpreted.

Over the past few decades, drain repair methods have improved beyond comprehension. Where in the past a problem with a faulty drain would have led to the drain being excavated and replaced, there are now a whole host of different solutions drainage companies can use to instigate a drain repair.

One of the recently used tools which has proved invaluable for drainage companies is the CCTV survey. Drainage companies are now able to see directly into the drainage system using a small camera which is inserted into the drain. Some companies even have remote controlled robots which can be inserted into the drainage system and then ‘driven’ along the drain to find the problem area.

Using CCTV cameras, the drainage company can visually see the problems with the drain so accurate repairs can be made. In the past a drain may have been excavated when it only needed jetting or intrusive roots trimmed. And sometimes whole lengths of drains were excavated to find a problem, when only a section of a few feet would now need to be replaced. Errors like these have now been eradicated and thanks to detailed surveys many of the jobs that would have taken a huge amount of time previously now only take a matter of hours to solve.
