Pitch Fibre Drain Repairs

Pitch Fibre Drain Repairs
(Re-rounding)

We have been carrying out repairs to damaged pitch fibre for a number of years and have perfected our no-dig repair solutions which involves reshaping the deformed pipe with our winch system.

What are pitch fibre drains?

Introduced in the 1940s, pitch fibre drain pipes were used extensively until the 1970s. Initially thought to be a better alternative to fired clay pipes, they were cheaper and lightweight, which made the easy to handle.

Made from wood fibre impregnated with coal tar, they performed well when dealing with normal waste water. Subsequently, they have been found to react badly when subjected to large quantities of hot water, oils and fats. This causes the tar soften and cause deformation and leaks in the pitch fibre drains.

The design life of pitch fibre drains has been estimated at 40 years, meaning that most have reached the end of their life expectancy. In severe cases they can collapse, blocking the drain completely.

How do you repair Pitch Fibre drains?

SaS Drainage have extensive experience repairing damaged pitch fibre drains.  We have perfected a ‘no dig’ repair solution, which involves reshaping the deformed pipe. This done by winching a ‘re-rounding cone’ through the damaged area. This returns the drain to its original shape. All of this can be done quickly and efficiently without the need for disruptive excavation.

After the procedure has been carried out, the pipe is cleaned and checked with our CCTV camera and once we are happy with the re-rounding, a Cured-In-Place Pipe (CIPP), structural liner is installed to hold the pipe’s shape, stopping any future deformation of the pipe.

Frequently asked questions

What problems can occur with pitch fibre drains?
  • Internal blistering, caused by deterioration can cause blockages and eventually close up the entire pipeline.
  • Pitch fibre is prone to deterioration caused by age, chemical erosion, weight stress and being poorly laid.
  • Over time, pitch fibre becomes porous, washing away subsoil and causing subsidence. This also attracts shrub and tree roots, causing further damage.
  • The delicate nature of pitch fibre means that the usual methods of drain clearance, e.g. high pressure jetting, can cause further structural damage.
What is the life expectancy of a pitch fibre drain?

Best estimates suggest that pitch fibre drains have a life expectancy of approximately 40 years.  The vast majority of pitch fibre drains were installed between 1950-1970, meaning that most have reached the end of their life expectancy. In severe cases pitch fibre drains have been known to collapse, blocking the drain run.

What does a Drain CCTV Inspection Look Like?

Our colour CCTV can easily identify where a pitch fibre drain is broken, and more importantly how best to fix the problem.

If there is a structural problem within the drain, then there are two main options of repairing it. The first is by excavating and the second is by using no-dig technology to return the pipe to its original shape and then reline it.
