Drain Relining

Drain relining (often called CIPP - cured-in-place pipe lining) is a specialist, no-dig method of repairing damaged drainage pipes by installing a resin-impregnated liner inside the existing pipe. Once cured, the liner forms a new pipe within the old one, sealing cracks, displaced joints, small holes, and root ingress pathways, and restoring the pipe's integrity without lifting floors or excavating gardens. Relining is particularly valuable when the defective section runs under patios, driveways, extensions, or landscaped areas where traditional replacement would be disruptive and expensive. A professional drainage engineer will typically start with a CCTV drain survey to pinpoint the fault, measure the pipe diameter and run length, and confirm the pipe is suitable for lining. Where needed, the pipe is cleaned and descaled with high-pressure jetting or mechanical cutters before the liner is installed and cured. TradeSupermarket helps you find vetted drain relining specialists near you who have the right equipment and experience for domestic foul drains, surface water lines, and commercial pipework. Listings make it easier to compare availability, reviews, and credentials, so you can choose a contractor who can diagnose the issue properly and provide a clear, written quote for the right repair method - whether that is a patch repair, full-length liner, or a local excavation for collapsed sections. Because drains are part of your property's critical infrastructure, quality and compliance matter. Reputable relining contractors work safely in accordance with UK health and safety requirements, carry appropriate public liability insurance, and will explain any implications for access points, flow, and downstream connections. If your drain serves multiple properties or connects to public sewers, they should also advise when water company consent or additional approvals may be required before work starts.
