The two most common trenchless sewer operations are pipe lining (also known as cured-in-place pipe lining or CIPP) and pipe bursting.
Pipe lining: Pipe lining involves inserting a flexible liner coated with a resin into the existing damaged pipe. The liner is inflated and the resin is cured, creating a new pipe within the old one. This method is effective for repairing cracks, leaks, and minor damage without the need for excavation.
Pipe bursting: Pipe bursting is used when the existing sewer pipe is severely damaged or needs to be replaced entirely. A new pipe is pulled through the old one while simultaneously breaking up the old pipe. This method is ideal for replacing old, brittle, or collapsed pipes without extensive excavation.
Both trenchless methods offer several advantages, including minimal disruption to landscapes, reduced costs, and shorter project timelines compared to traditional excavation methods. It's important to consult with a professional plumber to determine the most suitable trenchless method for your specific sewer repair needs.
