The Three Common Linings for Cracked Sewer Lines

Slip Lining

This method involves inserting a smaller, super-strong pipe into your old, cracked sewer line to create a strong and leak-proof lining. Here's how it works:

• A smooth, tough pipe is sized slightly smaller than your existing pipe.
• Small access holes are dug at the beginning and end of the damaged area.
• The new pipe is pushed or winched into the old line, creating a strong, leak-proof barrier inside.
• The gap between the old and new pipes is filled with grout for extra stability.

Pros of Slip Lining

• This method can handle more extensive damage than some other lining options.
• The new pipe creates a very durable lining that can extend the life of your sewer line.
• Compared to traditional digging, slip lining can be completed in a shorter timeframe as long as the job is handled by an experienced plumbing service.

Cured-In-Place Pipe Lining

This repair method uses a special resin-soaked sock to create a new lining inside your old pipe. These are the steps plumbers follow to restore sewer lines to good working order:

• The damaged pipe is thoroughly cleaned, and a sock impregnated with epoxy resin is inserted into the pipe through an access hole.
• The sock is inflated with air, pressing it against the pipe walls. Heat or hot water is used to cure (harden) the resin, creating a strong, smooth lining inside the old pipe.

Pros of CIPP Lining

• This method works well for pinhole leaks, cracks, and minor damage.
• CIPP creates a seamless lining throughout the repaired section.
• Since the sock is flexible, it can navigate bends and curves in the pipe.
