PITCH FIBRE MANAGEMENT
PROFESSIONAL PITCH FIBRE SERVICES
A considerable amount of drainage systems in properties from 1960-1970 were built using pitch fibre bitumen drains. With an approximate lifespan of about 40 years, it is quite common for us to see problems such as blistering, squashed, cracked or collapsed pipes preventing a free flow. We specialise in the rehabilitation of these problematic pipes using dedicated modern equipment and re-rounding and relining techniques.
Our services are backed up with a full 10-year guarantee for peace of mind.
WHAT IS PITCH FIBRE RE-ROUNDING?
In some cases, if the damage to pitch fibre pipes is not too severe, we can use no-dig repair methods to re-round and reline them.
Re-rounding involves winching heavy re-rounding tools of various sizes through the pipe to remove any bubbling and force the pipe back into shape. This process can re-round the drain to roughly 95% of its original circular diameter before we pass a metal brush through to remove any debris.
Once the pipe has been re-rounded and cleaned, we can reline them to help retain the shape and prevent any future deforming. You can find out more about our relining services on our drain relining page.
If your pitch fibre pipes have degraded beyond repair, then we would need to excavate the section or pipe that is damaged and replace with a modern alternative.
