NO DIG UV LINING DRAINAGE REPAIRS

70 Year Guarantee
WRC Approved
Environmentally Friendly

NO COMPROMISE ON SEWER PIPE REHABILITATION

Traditional methods of drainage pipe replacement under roads or properties would normally budget a huge cost, have higher safety risks and be programmed out for a long period of time. Drainforce can reduce costs by a considerable amount and increase productivity, whilst most importantly eliminating the safety risks on the network associated with traditional dig down pipe replacement methods.

Our methods of UV lining can create a far safer environment for workers while increasing productivity and reducing costs and environmental impact. We can UV line different from 100mm up to 2000mm with wall thicknesses from 3mm up to 30mm. Drainforce are WRC approved installers of Saertex Liners. We offer complete consultancy and design for every job.

About Drainforce UV lining

What is UV lining?
The Ultraviolet (UV) process involves inserting a liner into an existing pipe, the liner 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 old pipe, restoring the structural integrity of the drain, sewer or culvert.
