One of the tools that drainage experts use to tackle blockages in sewers and drains is the CCTV survey. Blocked or damaged drains can cause serious problems, which can be a real headache for homeowners. In the worst case scenario raw sewage can actually enter homes and can cause a significant amount of damage.
What is a CCTV survey?
CCTV surveys can be used by drainage companies to find the exact cause of a blocked drain immediately. A camera is inserted into the drain and images are relayed to the surface where the team of drain maintenance experts can review the pictures and decide on the most appropriate course of action. Using a CCTV survey also locates the exact position of the drain blockage so that pinpoint repairs can be made.
There are a few reasons why drains become blocked:
• Scale build up
• Silt deposits
• Settlement of dirt and debris
• Build up of fat
• Damaged or deteriorating drainage pipes
When the team of drainage experts have a reasonable idea what might be causing the problem they can tackle the problem quickly and effectively using either high pressure water jetting or another pertinent drain repair option.
