What is pipe lining?

Repairing underground pipes has historically been a costly and time-consuming process and often involved having to dig holes and attach new pipes to an existing drainage system. A number of alternative methods and technologies have been invented to make ‘no dig’ repairs a reality. One of these is pipe lining.

So what is pipe lining?

Pipe lining technology has been in development for several decades and is now used quite widely. It involves carrying out repairs from the interior of the wall and adding a sleeve lining inside the existing (often damaged) pipe. This essentially creates a new pipe from the inside of the old one.

What are the advantages/benefits?

There are a number of key benefits to this system. First and foremost, it removes the need to excavate, meaning no need for heavy and expensive equipment. This considerably reduces costs.

Secondly, there is much less disruption involved and it can be done at specified (quieter) times. This reduces downtime. Following on from this, the process is also much, much quicker, taking hours rather than days.

Other benefits include the fact that the lining aids flow rates, it can be flexible enough to negotiate bends, it is available in a wide range of lengths and diameters, and it is highly durable (usually lasting 50+ years).

Types of lining

There are two types of pipe lining: ambient cured and heat cured.

Ambient cured linings are used for the partial lining of drains and can either be dragged into the drain or inverted after they have been cut to the correct length. These are more commonly used on smaller properties.

Heat cured lining is used on pipes that are larger in diameter and length and lines the full length of the drain meaning it can cover multiple defects. It is installed using the inversion method.
