Trenchless sewer repair pros and cons

Trenchless pipe replacement is a new way to fix sewer pipes without digging a lot. This method is getting popular because it’s quick and saves money.

Definition and Basics

Trenchless pipe replacement fixes pipes underground without big trenches³. It’s great for older homes that often have sewer problems³. It’s also good in places like California, where old pipes break easily³.

Common Techniques Used on trenchless pipe replacement

There are a few main ways to do trenchless pipe replacement:

Cured-in-Place Pipe (CIPP) Lining: A special liner is put into the pipe. It hardens to make a new pipe inside⁴.
Pipe Bursting: This method uses water pressure to break the old pipe. At the same time, a new pipe is pulled in⁴.
Spray Lining: A special coating is sprayed inside the pipe. It makes a new, smooth surface⁵.
Slip Lining: A smaller pipe is put into the old one. Grout fills the gap to hold it in place⁴.

These methods have been around since the 1970s. They’ve improved a lot to fix different pipe problems⁵. Trenchless repairs usually take just one day³.

Trenchless Technique	Pros	Cons
Pipe Bursting	Minimal digging required Complete sewer line replacement Installation of a larger sewer line	Necessity of two pits Limitations on making turns within the pipe Minimum run length requirement of over 15 feet
Slip Lining	Quick and cost-effective repair Continuous slip lining options Reduced digging compared to traditional pipe replacement	Potential damage from improper grouting Smaller diameter for the new slip liner Requirement for two pits
Cured-in-Place (CIPP) Lining	No digging required Cost-effectiveness Durability Minimal impact on pipe diameter Applicability to various sewer pipe sizes	Curing time up to 24 hours Limitations in fixing certain sewer line issues like bellying Need for pre-and post-inspection with a camera

Choosing a trenchless repair method depends on the damage, budget, and personal choice⁴. For small problems, using an auger might be enough⁴.
