Pitch Fibre Drain Repair & Re-Rounding Services
Pitch fibre pipes found in older homes are prone to blistering and flattening, causing constant blockages that standard unblocking can’t fix. Instead of expensive replacement, we use trenchless Re-rounding tools to force the pipe back into shape and seal it permanently.

Do you own a home built between the 1950s and 1970s?
If your property was built between the late 1950s and early 1970s, there is a high probability that your drainage system is made of Pitch Fibre rather than clay or plastic.
Pitch Fibre was a cheaper alternative used during the post-war building boom. It is essentially paper pulp impregnated with pitch (tar). While it worked for decades, it has a fatal flaw: it is not designed to last forever. Over time, hot water and fats weaken the pipe, causing the bottom to blister and the pipe to squash into an oval shape under the weight of the ground.
The Symptoms of Failing Pitch Fibre
- Frequent Blockages: Because the bottom of the pipe is blistered/bumpy, toilet paper catches easily.
- Slow Draining: As the pipe squashes flat (ovalisation), the flow rate is drastically reduced.
- No “Flow” after Unblocking: You might clear a blockage, but the water still drains slowly because the pipe itself has narrowed.
Don't Dig It Up – Re-round It!
In the past, the only way to fix Pitch Fibre was to dig up your entire driveway or garden to replace the pipes. This is messy, expensive, and disruptive.
Drain 247 offers a “No-Dig” solution called Re-rounding. How It Works:
CCTV Survey: We confirm the pipe is Pitch Fibre and check the level of deformation.
Re-rounding: We insert a specialist winched “Re-rounding Tool” through the pipe. This acts like a forceful expander, pushing the squashed pipe back into its original circular shape.
CIPP Lining: Once the pipe is round again, we install a structural Cured-In-Place Pipe (CIPP) liner. This hardens to create a new, solid plastic pipe inside the old one.
The result is a brand new structural drain without digging a single hole in your driveway.

Frequently Asked Questions
Can all Pitch Fibre be re-rounded?
Not all. If the pipe has collapsed completely or squashed by more than 40-50%, it may be too damaged. We will confirm this with a CCTV survey first.
Is re-rounding cheaper than excavating?
Yes, significantly. Excavation involves skips, labour, and reinstating driveways/patios. Re-rounding is faster, cleaner, and cheaper.
How long does the liner last?
A properly installed liner has a life expectancy of 50+ years, effectively renewing your drains for the lifetime of your ownership.
