Cipp Drain Relining in Preston , Lancashire

You have to keep the water off while the liner is inflated and curing, which usually takes between two to four hours depending on the resin system we use. We will let you know the exact time window before we wet out the liner so you can plan around it. Once the resin hardens and we finish trimming the ends, you can use your bathrooms and kitchen normally straight away.

The liner only reduces the internal width by about three to four millimetres, which makes no practical difference to capacity. Because the cured resin creates a completely smooth, jointless surface, water and waste actually flow faster than they did against rough, scaled Victorian clay. That slick finish also removes the jagged joints where toilet paper and wet wipes usually snag.

The continuous liner covers over any incoming side connections when it inflates against the host pipe, so we map their exact positions with a CCTV camera beforehand. Once the resin sets hard, we send a specialist robotic cutting tool down the line to mill out the blocked junctions from the inside. This restores full flow to your kitchen and bathroom branches without digging up the ground above the junction.

If a pipe has completely pancaked flat or filled with packed subsoil, a liner cannot pass through because there is no channel left to hold the shape. CIPP is ideal for cracked, fractured, or leaking pipes, but a total collapse means we have to dig down to replace that specific failed section first. We always carry out a full CCTV camera inspection first to check the line still has enough shape to support the structural sleeve.

No, because CIPP forms a seamless, rock-hard pipe inside the old one that completely seals off the gaps where roots entered. We clear all existing roots out with high-pressure water cutters and thoroughly descale the clay pipe before we put the resin sleeve in. With no open joints, fractures, or moisture escaping into the soil, tree roots have no way to sense the water or force their way inside.

The structural CIPP liners we install have an engineered 50-year design life. The finished resin pipe stands up on its own against ground movement and heavy surface loads without relying on the old outer pipe for support. It is completely resistant to corrosion, ground acid, and household chemicals, giving old clay drains the lifespan of a brand-new installation.
