Non disruptive, environment friendly. An increasingly viable option to traditional excavation techniques.
As a repair process, drain lining has been in use for many years. Initially it was developed to renovate large diameter main sewers. It is now an extremely popular method of repairing smaller diameter domestic drains in the UK.
K.G. Drain Services' operatives have been successfully lining and relining drains for over a decade. It is generally cheaper, less disruptive and cleaner to line a drain than to renew it, involving little if any disturbance of the ground on which the drain is laid.
Innovations in drain lining
KG Drain Services make a point of staying at the forefront of drain lining developments. Drain liners have been created which can be applied around bends without wrinkling - a major drawback in the past, especially in 100mm diameter drains. They have also been developed to change diameter part way along a drain and then revert to the original dimensions further down the line.
Patch liners - the cost-effective alternative
Patch liners can be used to repair localised damage where full end-to-end lining would be unnecessary. This method involves placing a piece of impregnated matter on an elongated inflatable bladder and guiding it into place with the help of a CCTV camera. When it is precisely located, the bladder is inflated, pressing the patch into place. The pressure is maintained until the patch has cured, the bladder is then deflated and withdrawn, and the job is done. Patch liners are becoming increasingly popular for dealing with isolated defects, offering a cost-effective alternative to a full liner or other repair.
