What to know about drain lining

Drain lining, also known as cured-in-place pipe (CIPP) lining, is a popular method for repairing damaged drains and sewers in the UK without the need for extensive excavation.

What is drain lining?

A resin-soaked liner must be inserted into the pipe that requires repair. This liner is then expanded and allowed to harden, thus forming a new, strong pipe within the original, damaged pipe. This trenchless technology eliminates the need for digging up large areas, making it less disruptive and quicker than traditional methods.

When would I need my drains lined?

You may need your pipes repaired, for example, if there are cracks or leaks, or even minor structural damage. Drain lining is effective in sealing pipes that have been infiltrated by tree roots, and is useful for fixing pipe joints. Lining also extends the life of ageing pipes that are still structurally sound.

Homeowners opt for drain lining Reading to repair their damaged pipes quickly and efficiently, avoiding the disruption of traditional excavation methods. If you require drain lining in Reading, speak to a professional in the area.

What are the benefits of drain lining?

It’s generally cheaper than traditional excavation and replacement methods. The process can be completed in a matter of hours rather than days. There is little to no disruption to landscaping, driveways, or buildings. The liner can last for several decades, and it’s eco-friendly.

It’s also one of many modern methods in construction and drainage. According to the BBC, engineers have inserted a special lining into a fractured sewer pipe to repair it without digging up a road.

What is the actual process?

A CCTV survey is conducted to evaluate the condition of the pipe and determine if lining is suitable. The pipe is then cleaned thoroughly to remove debris, scale and any obstructions. A flexible liner with resin is pushed into the pipe. The liner is expanded to fit snugly against the inner walls of the pipe. It is then cured, typically using hot water, steam or UV light, to harden the resin. Another CCTV survey ensures the liner is properly installed.
