    What Are Pitch Fibre Pipes and Why Were They Used?

    As a business owner on the South Coast, maintaining your property’s drainage system is essential for protecting your investment. But if your property was built between the 1950s and 1970s, you may be facing an invisible threat—pitch fibre pipes. These outdated pipes were once a popular drainage solution due to their affordability and ease of installation, but in 2025, they are a ticking time bomb.

    In this blog post, we’ll explain what pitch fibre pipes are, why they fail, and what you can do about it—including the latest pitch fibre repair options and drain relining costs. With expert insights and actionable advice, this guide will help you take the right steps to safeguard your business.

    Pitch fibre drainage pipes were introduced post-WWII as a lightweight and cost-effective alternative to clay and concrete pipes. Made from wood cellulose impregnated with coal tar pitch, these pipes served the housing boom across the UK, including commercial properties along the South Coast.

    However, pitch fibre pipework was never intended to last more than 40 years. Today, many of these installations are well past their lifespan, resulting in widespread issues.

    Common Problems with Pitch Fibre Drains:

    • Delamination: Layers of the pipe start peeling away due to water pressure.

    • Deformation: Pipes become oval-shaped or collapse under ground pressure.

    • Blistering: Chemicals and heat from wastewater cause bubbles and weaknesses.

    • Root Infiltration: Cracks invite tree roots to grow inside the pipework.

    2025: Why This Is the Year to Act

    With changing environmental regulations, stricter building inspections, and rising water table levels, 2025 is the year to assess your pitch fibre drainage system.

    Key Statistics:

    • According to Water UK, up to 30% of properties built before 1980 still use some form of pitch fibre drainage pipes.

    • Drainage failure accounts for over 60% of commercial property maintenance costs annually.

    CCTV drain surveys are the most effective way to identify the condition of your pipes. Look out for:

    • Frequent blockages

    • Slow draining sinks or toilets

    • Bad odours near drain access points

    • Subsidence or unexplained ground movement

    Professional surveyors use high-resolution cameras to inspect internal pipe conditions, including signs of collapse, blistering, and deformation. This can help determine whether you need re-rounding pipes or a full replacement.

    Drain Relining (Fibre Lining Repair)

    A trenchless, non-invasive repair method where a resin-soaked liner is inserted into the pipe and inflated to harden against the walls.

    Benefits:

    • No digging or disruption

    • Cheaper than replacement

    • Reinforces structural integrity

    Average drain relining cost in 2025: £75–£120 per metre, depending on pipe diameter and access.

    Pipe Replacement

    Involves excavating the old pipe and installing new PVC or clay pipes.

    Recommended when:

    • The pipe has fully collapsed

    • There are multiple joints and fittings at risk

    • The property is undergoing significant renovation

    Cost estimate: £200–£400 per metre including excavation and reinstatement.

    Why South Coast Businesses Should Prioritise Pipe Repairs

    Whether you run a café in Bournemouth, a warehouse in Portsmouth, or a guesthouse in Brighton, ignoring your drainage could result in:

    • Health & safety violations

    • Property damage

    • Flooding and costly cleanups

    • Insurance complications

    Many commercial insurers are tightening policies around outdated drainage infrastructure. Documented drain repair or relining can improve your premiums and compliance status.
