What a CCTV Drain Survey Finds in Older Wolverhampton Homes
What Does a CCTV Drain Survey Reveal in Older Wolverhampton Homes?
The drainage system of older Wolverhampton properties have rarely been inspected. What the camera discovers is generally not what the home owner expected.
Cracked and Collapsed Clay Pipes
In homes built prior to 1970, the majority of pipes will be made of clay which, as decades pass, can become brittle and prone to cracking due to ground movement, frost attack or even simple aging. Such cracks can allow soil to enter the pipe to cause a restriction whilst, simultaneously, allowing more soil to enter the pipe thus exacerbating the problem. In some cases, the clay pipe may have partially collapsed allowing little or no flow through the pipe and causing severe flooding.
Root Intrusion From Mature Trees
Wolverhampton has many older streets with mature trees. The roots from these trees will often find their way into the pipes at joints. These roots will then grow in mass filling with debris which can cause blockages to occur on a regular basis. A drain survey camera will be able to show up the root mass in the pipes which a simple rod and plunger will be unable to diagnose.
Legacy Combined Sewer Layouts
- surface water and foul water are carried down the same pipe runs. This form of sewer can cause problems during periods of heavy rainfall, and create a number of difficulties when attempting to carry out any planned works to the drainage system. A CCTV Drain Survey Wolverhampton can highlight what type of pipes are present and how they are connected together.

Mismatched Materials From Patch Repairs
Decades of repair work on a home’s drainage system can result in a mix of old and new pipes. Many areas of modern plastic pipe run alongside original clay or even older pitch-fibre pipes. Misaligned and therefore failed joints between these different materials are a common problem that can be exposed by a CCTV Drain Survey.
Pitch-Fibre Pipe Deformation
Pitch-fibre pipes, which were a cheaper alternative to clay pipes used in the 1950s and 1960s, are another common item found within older drainage systems. These pipes are prone to absorbing large amounts of moisture over time, leading to deformation of the pipe into an oval shape.within confined spaces make it impractical to carry out manual inspection of buried drain runs. Therefore, a CCTV drain survey is the only realistic way to confirm deformation of pitch-fibre pipes and assess how far they have been affected.
