Pitch fibre pipes were commonly installed between the 1950s and 1970s; they were introduced as a cheaper alternative to the more standard clay pipes. These days new drainage pipes are usually made from plastic, but there are still miles and miles of pitch fibre drainage pipework across the UK, mostly for properties built between the 1950s and 1970s, where there has never been a reason to replace and update them.
Pitch fibre pipes are made from wood cellulose impregnated with inert coal tar pitch.
A damaged pipe can be relined using a polyester and felt lining which is applied internally and covers any cracks or small holes in the pitch fibre pipe. If this is not a suitable approach we may also consider patch lining, where we use a patch to cover a crack or hole. In some instances, if a pipe has more serious damage we may consider Brawloliner. This is a seamless elastic tube which can be used to line pipework that is under intense pressure and perhaps has more joints and corners to contend with.
