UKDN Waterflow’s UV lining process is the fastest and most cost-effective way to repair a collapse or damaged pipe. Unlike most cured-in-place-pipe (CIPP) liners, the UKDN Waterflow UV system is cured by ultra-violet light rather than hot water. Not only does this allow much quicker installation and curing, but it also avoids any risk of pollution from the disposal of contaminated water.
The UV Lining process
The process involves inserting a Glass Reinforce Polyester (GRP) liner impregnated with a special resin into the sewer or drain. As the liner is inserted into the pipe, it is pulled into place and then inflated with free air. A UV Light Train with built in CCTV is pulled through to check the positioning and identify any obstructions. Finally the UV lights are ignited causing the resin cure and effectively creating a new pipe within the pipe and restoring the integrity of the drain or sewer.
Benefits of UV Lining
Rapid installation
Fast set up and installation times allow work to be completed within short time frames. Liners can be installed quicker than any other method available. This makes particularly suitable for use in high utilisation areas like Railways, Roads & Airports
Restricted access overcome
UV cured lining enables work to be completed in awkward locations due to the minimal amount and portability of the equipment used.
Environmentally friendly
The UV liner process eliminates any environmental risk of styrene.
No-dig
Disruption is also kept to a minimum with our UV lining process restores structural integrity to defective pipes and sewers without any unnecessary disruption.
Durable and long lasting
The high-strength, Glass Reinforced Polyester (GRP) liner was designed to provide a 70 year design life, which makes it suitable for high load situations on diameters from 150 mm to 1200 mm.
