CCTV – Find Out What Is Really Going On Underground
Over time, drains and sewers, like all of us get older and in time will deteriorate and get worse. Walls can collapse, blockages can occur and the result is that you get drainage problems. The cause can be things like ground movement, intrusion from things like tree roots or it could be that the drains are simply badly constructed in the first place.better to know rather than guess at the root cause of problems underground
The simple fact is that you cannot tell from above ground exactly what is going on with a drain that is underground. You need to know exactly what is going on- where the blockage is happening for example, so the best solution can be found. Blockages can be from many causes, organic or otherwise, they need to be removed and quickly so that problems don’t worsen
Once you know that you have a drainage problem, there are a couple of ways that you can diagnose the problem. Using CCTV, there are two systems available to you. These are the push rod and also available is the crawler system. The push rod and the crawler system are both available through reputable drainage specialist- better perhaps to know that they are available so you can ask your drainage contractor which they carry. They should carry both systems
The crawler system is used for drainage pipes over 150mm in diameter. Smaller drainage systems (less than 150mm) are diagnosed using the push rod system. Full, detailed reports are then compiled to show exactly what is wrong with the drain so you can then decide what is the best method of solving the drainage problem
An experienced CCTV operator will look out for a variety of problems. Collapsed drains can look remarkably similar to blocked drains and the two problems may need to be tackled in different ways. Tree roots can be seen through the camera lens. Surveys can be written up into a document and then written to a DVD so that they can be stored and recalled easily in the future
If you are planning to build and extension to a property, CCTV can be used for a build over survey. Basically, this is a survey of the drainage condition underground so that you can see the condition before building over them. If you bury a problem, it will be much more expensive in the future should problems arise in the future
