Blocked drains are more than just an inconvenience—they’re a potential hazard to both residential and commercial properties. Whether you’re searching for “blocked drains Bournemouth”, “drain unblocking Chichester”, or wondering “how to unblock an outside drain”, understanding the root cause of drainage issues is critical.
A common culprit across properties in Dorset and beyond is ageing pitch fibre drainage pipes. These were widely used from the 1950s to 1970s but now cause persistent blockages and collapses if left untreated. Fortunately, pitch fibre re-rounding services offer an effective solution.
Pitch fibre pipes were considered innovative at the time—lightweight, cheap, and easy to install. However, decades later, they’re showing their weaknesses. Made from wood cellulose and coal tar, these pipes soften over time, distort under pressure, and eventually collapse.

Learn MoreAuthoritative Source: According to the UK Building Research Establishment (BRE), pitch fibre pipes degrade significantly after 40–60 years, affecting tens of thousands of properties nationwide.
Pitch fibre re-rounding is a trenchless, non-invasive repair technique that restores the original shape and functionality of deformed pipes. This process is far more affordable than a full pipe replacement and can extend the life of your drains by decades.
CCTV Drain Survey: Using advanced inspection tools to assess the extent of damage.
Re-rounding with a Winch: A specially designed tool reshapes the collapsed or squashed pipe.
Structural Lining: Once re-rounded, the pipe is relined internally with a resin liner, strengthening the structure and preventing future issues.
While emergency drain unblocking can solve immediate blockages, it doesn’t tackle the underlying structural issues. Many homeowners and businesses rely on quick fixes but are unaware that the problem often stems from their old pitch fibre pipes.
Contact our TeamCase Example: A recent client in Gillingham suffered repeat flooding every 6 months. After a thorough CCTV inspection, we discovered a collapsed pitch fibre line. Re-rounding and lining restored the pipe without excavation, saving the client thousands in future emergency callouts.
Outdated pitch fibre drains are a hidden ticking time bomb for properties across Dorset and the UK. While quick fixes like searching for the best toilet unblocker or learning how to unblock outside drains may offer temporary relief, they don’t solve the core issue.
