A bespoke UV sensitive resin impregnated liner is pulled into position using a winch, the light train is lowered and inserted into the liner and end packers are fitted. The liner is now ready to be inflated until it has taken to the size and shape of the host pipe.
The light train is pulled through the liner, once it is at the far end of the pipe the UV lamps are turned on in sequence and the liner begins to cure under the UV light. The light train is pulled back mechanically at a controlled speed determined by the thickness of the liner and diameter of the host pipe, readings are sent back to the control unit every two seconds, ensuring a full and precise cure is achieved.
Data is simultaneously sent to the rig operator and the liner manufacturer for Quality Assurance purposes.
- The very latest method in trenchless technology
- Offers a considerably lower carbon footprint than that of other alternative methods as it requires a minimum expenditure of energy and removes any environmental risk of styrene pollution.
- Can be installed quicker than any other method available making it a great solution for use in busy and highly trafficked areas.
- Requires relatively small amount of equipment compared to other methods available meaning works can be undertaken in restricted access or hard to reach areas.
