Sewer lining is an important technique used in the repair and maintenance of ageing or damaged sewer systems without the need for extensive excavation. Let’s look at five methods of drain lining so you can see which is right for you.
1. Cured in place pipe (CIPP) lining
Cured in place pipe (CIPP) lining is one of the most widely used trenchless repair methods and involves inserting a resin-saturated felt tube into the damaged pipe. The tube is then inflated to fit the pipe’s interior walls and cured, creating a new, strong pipe within the old one.
- QuickLock point repair
QuickLock point repair is a trenchless pipe repair method that focuses on fixing cracks, leaks, or displaced joints within a pipeline. A stainless-steel sleeve is placed inside the pipe at the damaged area, then expanded and locked in place to seal the problem.
3 Cured in place point repair
Cured in place point repair is similar to CIPP lining but is used for small repairs such as cracks or holes. In this method, a short section of resin-impregnated liner is inserted into the pipe and positioned over the damaged area. The liner is then cured in place, typically using heat, to create a strong, seamless patch.

4. Sliplining
Sliplining is one of the oldest methods of trenchless sewer repairs. This process involves inserting a new, smaller-diameter pipe into the existing damaged pipe. The space between the old and new pipes is filled with grout to hold the new pipe in place. Although sliplining makes the pipe slightly smaller, it creates a new, leak-free pipe inside the old one.
- Internal pipe coating
Internal pipe coating is a method whereby the interior of the pipe is sprayed with a protective coating, such as epoxy or polyurethane. Internal pipe coating is typically used for pipes that have minor defects and will extend the life of the pipeline by protecting it from future damage.
