Pipes made from pitch-fibre were often used in the 1950s and 60s. They are known to have a much shorter life span than pipes made from clay or heavy-duty plastic. Although this form of piping is quite out-dated there are still many miles of pitch fibre pipe work systems in operation.
As you would expect this form of pipe is known to collapse and becomes misshaped when under any kind of external pressure. There are luckily a number of methods available should you experience any problems.
The video below shows a survey we conducted using CCTV surveys in order to examine Pitch Fibre Warping.
