Drain lining is the modern world’s gift to those responsible for cracked or leaky pipes. It is a non-invasive method of getting inside drains and lining them with a new polymer interior. The approach essentially creates a new pipe within the old one. Patch lining is conducted in a similar way but is used when only certain areas of a pipe need to be repaired and other sections are fine.

Preparatory work

Before a drain can be lined or patched, it must be checked and cleared of any debris or blockages. People putting inappropriate substances – such as wet wipes, fat or concrete – down drains can cause immense problems. In Central London, a sewer was blocked by a mass of concrete that weighed more than 100 tonnes.

To assess whether a pipe needs a full lining or just patching, the drain is cleaned and a camera is inserted so that the interior can be inspected. The liner is then fed into the drain and positioned correctly by the use of an inflatable airbag. Heat is used to activate the lining, which cures and sets.

With patch lining, sections of liner are inserted and manoeuvred into place where needed to repair leakages.

The drain lining company will insert a camera at the end of the works to check that all issues have been rectified.
