    The Silent Threat of Old Pitch Fibre Drains

    If your home or business on the South Coast still relies on old pitch fibre pipes, you could be facing hidden dangers beneath your property. Originally installed between the 1950s and 1970s, pitch fibre drains were once a popular solution due to their affordability and ease of installation. However, with time, these pipes have proven to be highly vulnerable to deterioration, leading to costly repairs and serious drainage issues.

    Understanding the risks of pitch fibre pipes and knowing how to fix them is essential to maintaining a safe and functional drainage system. In this comprehensive guide, we’ll explore the dangers of outdated pitch fibre pipework, discuss effective solutions such as pitch fibre drain replacement in Hampshire and Dorset, and explain how techniques like drain rerounding can extend the lifespan of your drainage system.

    Degradation Over Time

    Pitch fibre pipes are made from a mix of wood cellulose and coal tar, which, while lightweight and easy to install, are prone to structural failure. Over the decades, water exposure, pressure, and chemical reactions cause pitch fibre pipes to blister, collapse, and become misshapen. This results in reduced flow efficiency and increased risk of blockages and leaks.

    Susceptibility to Deformation

    Unlike modern drainage materials such as PVC or clay, pitch fibre pipes weaken under pressure. If subjected to prolonged stress from soil movement or heavy loads, these pipes may collapse, leading to severe drainage issues and potential property damage.

    Increased Blockage Risks

    Due to the way pitch fibre pipes degrade, they often become rough inside, leading to debris accumulation and frequent blockages. This is particularly problematic for businesses and households in Bournemouth, Dorset, and Hampshire, where outdated infrastructure is still in use.

    The Best Solutions for Failing Pitch Fibre Pipes

    1. Pitch Fibre Drain Repair in Dorset and Beyond

    For minor damage, pitch fibre drain repair methods such as drain lining can provide an effective solution. This technique involves inserting a resin-coated liner into the pipe, which hardens and restores structural integrity. This is a cost-effective solution that extends the lifespan of existing pipes without extensive excavation.

    2. Drain Rerounding – Reshaping Your Pipes

    If your pitch fibre pipes have become deformed but are not completely collapsed, a technique called drain rerounding may be the ideal solution. This involves inserting a mechanical tool into the pipe to reshape it back to its original circular form before applying a durable liner for reinforcement. Re-rounding pitch fibre pipes ensures improved flow and prevents further degradation, making it a popular choice for property owners on the South Coast.
