In the 1950s and 60s, pitch fibre pipes were widely installed in new properties across the UK, promoted as a modern alternative to traditional clay pipes. Lightweight, affordable, and easy to install, they seemed revolutionary at the time. But decades later, these pipes have proven to be one of the most unreliable drainage materials ever used.
Made from wood cellulose and coated in coal tar, pitch fibre may look sound on the surface—but underground, these pipes are prone to deformation, blistering, and collapse. If left unchecked, they can cause repeated blockages, water pooling, and even total system failure.
If you suspect your drainage system includes pitch fibre pipework, we strongly recommend arranging a CCTV drain survey with our expert team to assess the condition before serious damage occurs.
At District Drainage & Water Services, we’re fully equipped to carry out pitch fibre pipe re-rounding and lining using advanced no-dig trenchless technology. This means we can restore the shape and integrity of your drains without digging up your property—saving you time, mess, and major excavation costs.
Once the pipe is re-rounded to its original shape, we install a durable internal liner, creating a new pipe within the old one. This process:
When full pipe replacement isn’t possible—or isn’t necessary—drain relining is a cost-effective, long-term solution. Using cured-in-place lining technology, we create a strong, seamless inner layer that seals cracks, restores flow, and prevents further deterioration.
Whether it’s a pitch fibre system or another damaged material, our trenchless lining method brings your drains back to like-new condition, with minimal disruption to your property.
All relining work is carried out by our experienced engineers and backed by long-term guarantees.
