The process of drain relining typically begins with a CCTV survey to identify the location and extent of the damage. Once the damaged area has been identified, a patch liner or a full-length liner is inserted into the pipe. The liner is then inflated with air or water, and a special resin is used to cure the liner in place. This creates a new, watertight pipe within the old one.

Drain relining offers a number of benefits over traditional excavation methods. It's a faster and more cost-effective solution, as it eliminates the need for digging up your garden or driveway. It's also a more environmentally friendly option, as it reduces the amount of waste generated by excavation.

You may need drain relining if you have a damaged or broken pipe that's causing problems with your drainage system. Some common signs that you need drain relining include:

• Slow draining or gurgling sounds from your drains
• Backed-up sewage or wastewater
• Cracks or fractures in your pipes
• Root intrusion or other forms of damage
