Drain lining is a trenchless technology used to fix damaged or deteriorating pipes without the need for extensive excavation. This method is highly effective in addressing a variety of issues, such as cracks, leaks and corrosion, while minimising disruption.

How do you know if your drain needs lining?

Signs that your drain needs relining include frequent blockages, slow drainage, unpleasant odours, visible damage, water stains, or strange noises. If you consistently experience blockages or notice a decrease in drainage efficiency, it may be indicative of underlying issues such as cracks, leaks, or root intrusion. Regular monitoring and addressing these signs quickly can help prevent more extensive damage.

How drain lining works

Before initiating drain lining, a thorough inspection of the pipes is conducted. This is often done using advanced technologies, such as CCTV surveys, to identify the extent and nature of the damage. The damaged pipe is then cleaned thoroughly to remove any debris, scale or roots that could compromise the adhesion of the lining.

A flexible liner, typically made of materials such as polyester or fibreglass, is saturated with a resin mixture. This liner is then inserted into the damaged pipe using air or water pressure. Once in place, the liner is inflated to conform to the interior of the existing pipe. The resin is then cured using heat or ultraviolet light, creating a solid and watertight inner layer.

Benefits of drain lining

Unlike traditional excavation methods, drain lining minimises disruption to the surrounding environment. This is particularly beneficial for residential areas, commercial spaces, or places where excavation is impractical.

The trenchless nature of drain lining also allows for quicker implementation compared to traditional pipe replacement methods.
