Pitch Fibre

Pitch Fibre pipes were mainly used in the 1960’s – 70’s and is made from wood cellulose fibre impregnated with carefully refined inert coal tar pitch. It was a revolution in its time due to the long lengths making it a lot easier to install rather than the traditional clay pipes and also being a lot cheaper.

The problems…

Due to the make up of the pipe it has a tendency to de-laminate/blister or become deformed and flattened/misshapen thus leading to blockages and collapsing of the pipes. The pipes can also leak and can attract tree roots into the pipe work.

Although the pitch fibre was considered a good material to make drains from in the 1960’s it soon became apparent it would not be able to stand up to the things put down our drains i.e. cleaning products such as bleaches/fats and other solvents. These all help to speed up the deterioration and breaking down of the pitch fibre.

Our solutions

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. After this has been carried out the pipe is cleaned and checked with our CCTV camera and once we are happy with the re-profiling a CIPP (cured-in-place pipe) structural liner is installed to hold the pipe into shape stopping any future deformation of the pipe.

For any pitch fibre problems and advice please contact us on our free phone number or by email. We believe our services are competitively priced within the market and all our work is guaranteed. Our aim is to provide a courteous and efficient service with a very high standard of workmanship.
