Pitch Fibre Pipe Repair Across
Slough

Many residential and commercial properties in Slough, particularly those built between the 1950s and 1970s, were constructed using pitch fibre piping. While cost-effective at the time, these pipes were made from wood cellulose impregnated with coal tar, which eventually degrades. Over the decades, the internal layers begin to blister and peel, creating immediate obstructions that catch waste and paper.

Beyond simple blockages, these pipes often suffer from ovalisation, where the weight of the surrounding soil causes the pipe to squash or collapse. If you notice your kitchen sink, toilet, or external gullies backing up repeatedly, it is a strong indicator that the internal integrity of your drainage runs has been compromised. Rather than temporary, high-pressure jetting that only removes the immediate obstruction, we focus on identifying and permanently fixing the root cause.

We never guess at the condition of your underground pipework. Our first step is a high-definition CCTV drain survey to accurately map the extent of any delamination or structural collapse. Once the fault is located, our team uses specialised mechanical re-rounding tools. These are winched through the affected section to restore the pipe to its original circular profile, clearing the way for a structural repair.

After re-rounding, we install a CIPP (Cured-In-Place Pipe) structural liner. This is an epoxy-impregnated resin sleeve that is inverted into the damaged pipe and allowed to cure against the internal walls. The result is a smooth, seamless, and structurally sound pipe within the old one. This no-dig method is highly effective for properties with expensive driveways, landscaped gardens, or commercial access points where traditional excavation would be both costly and disruptive.

Slough’s proximity to the Jubilee River and the Thames floodplains means that local ground conditions are often saturated. This moisture-rich soil places additional stress on ageing pitch fibre systems, often accelerating the rate of collapse or root infiltration. Our 15 years of operational experience in the SL3 postcode means we know exactly how to address these local challenges effectively. We prioritise long-term performance, ensuring that our repairs comply with modern standards for flow and structural support. By choosing a local, independent team, you avoid the administrative wait times of national franchises and receive direct, professional care from those who actually perform the work.

Does a cracked or leaking drain always require digging? Not at all. With modern trenchless technology, we can perform structural patch repairs and full-length relining from existing access points or manholes, keeping your property clean and intact.

Who is responsible for the drain outside my property boundary? In Slough, drains that only serve your property and remain within your boundary are your responsibility. If the drain leaves your curtilage or serves multiple properties, it typically falls under the remit of Thames Water.

Why does the blockage keep returning? If your pipes are made of pitch fibre, they are likely blistering or deforming. Standard jetting will clear the path temporarily, but the internal wall of the pipe remains uneven, causing debris to snag again. A structural liner is the only way to seal these defects permanently.

What is the benefit of a CCTV survey before repairs? It allows us to pinpoint the exact depth, location, and nature of the damage. This ensures we provide an accurate quote and select the correct repair method without unnecessary guesswork.
