Compared with traditional lining methods, Sapphire Utility Solutions’, UV lining service, is a faster, more cost effect and environmentally friendly way of repairing or renovating pipes. With only a four-man crew required and no need for a boiler on site to ensure hot water, UV lining can be used in compact sites in city centre areas, as well as more environmentally sensitive sites, due to the lack of styrene contaminated water.

The resin used in the liner is also chemical-resistant, making it a perfect solution for the petrochemical industry as the liner will not rot or erode as chemicals pass through the pipe.

The process involves inserting a liner into the pipe that is infused with a special resin, containing UV initiators. A UV Light Train with built in CCTV is pulled through to check the positioning and identify any obstructions.

The UV lights are then activated, causing the resin to cure. This effectively creates a new pipe within the pipe, restoring the structural integrity of the drain or sewer.
