For the most part, sewer lines remain out of sight and out of mind. But when these lines crack, the resulting property damage and health risks can be hard to avoid.  The good news is that, in many cases, the problem can be repaired by relining the pipe, rather than digging out a trench and replacing the entire section. To help explain how trenchless sewer repair works, Chugach Sewer & Drain in Anchorage, AK, highlights the basics behind four common pipe lining options.

4 Effective Trenchless Sewer Repair Methods and When to Use Them

1.  Epoxy Pipe Coating

Internal pipe coating is a simple and effective option for small cracks that are at risk for leaks and minor soil contamination. This method requires the channel to be completely drained of waste and water. After it’s clear, professionals use a special epoxy spray that will solidify to seal any existing cracks. In addition to stopping leaks, this treatment may also help improve flow.

2. Cured-in-Place Piping  

A cured-in-place pipe is one of the most versatile forms of trenchless sewer repair that can address minor to moderate damage. Essentially, this technique involves inserting a specialized sleeve into a cleared pipe and using steam to seal it into place. Typically, these sleeves can accommodate pipes as large 110 inches in diameter.

3. Pull-in-Place Lining

Similar to the cured-in-place technique, pull-in-place involves lining a damaged pathway with a specialized sleeve. However, this sleeve is made out of an epoxy material that is more appropriate for large openings. To install the sleeve, crews must dig two small access points at both ends of the pipe, and pull the sleeve through the entire length. Next, air is used to position and dry the material in place.

4. Pipe Bursting

When other methods of trenchless sewer repair aren’t appropriate or entire sections of the line need to be replaced, pipe bursting may be necessary. While no trenches are needed, crews will have to dig access holes at both ends of the channel. Once these access points are established, a bursting head is pulled through the original pipe, breaking apart the material with tough fins. As the old material is destroyed, a new plastic pipe moves into place to create a seamless pathway for sewage.

While each method offers its unique advantages, all forms of trenchless sewer repair can save you a considerable amount of money, stress, and property damage.
