Excavation vs. Trenchless: Two Kinds of Sewer Repair

There was a time when sewer line repair at your Westfield, IN home or place of business would almost certainly have involved excavation, which is to say, digging up the pipes to get at and fix the problem. These days, however, the experts at 24-7 Plumbing are often able to use trenchless methods to deal with an issue As the name implies, trenchless sewer repair means there’s no digging involved.

Modern sewer repair of either type begins with a sewer inspection using a video camera at the end of a cable. Sliding the cable down the length of the sewer pipe allows plumbers to assess its condition and pinpoint problems without the need to dig it up. Depending on what the sewer inspection finds, they’ll then proceed with either sewer excavation or trenchless methods.

SEWER LINE EXCAVATION

Today, workers mostly use sewer line excavation when laying a new sewer line or when an old sewer line is so extensively damaged that sewer line replacement is the recommended approach. In those situations, obviously, you have to dig.

It can also be the preferred, more economical sewer repair option in some situations where the line is free of obstacles.

In many other circumstances, however, it’s not the more economical option. This is likely the case if it will impact landscaping or drainage areas above the sewer line or when there’s concern about damage to driveways, patios, and other paved areas. In those instances, plumbers will generally recommend trenchless sewer line repair when it is feasible.

TRENCHLESS SEWER REPAIR

As mentioned above, trenchless sewer repair accomplishes its purpose without the need for digging, and this is often the quicker, less expensive, and less disruptive alternative. There are various methods. Here are two we frequently use:

  • Sewer pipe lining. Using an existing access point, we draw a flexible plastic and resin tube inside the old pipe. We then apply steam and heat to harden it in place. The new CIPP (cure-in-place-pipe) lining deals with cracks and leaks by covering them up without appreciably diminishing the width of the sewer line.

  • Pipe bursting. This is a technique for removing hopelessly collapsed or broken pipes without sewer repair excavation. We send in a special tool call a bursting head on a cable. As it pushes its way through, the bursting head breaks the old pipe and pushes it away. Coming along behind the bursting head is a new piece of pipe that the cable pulls into place. Pipe bursting has successfully replaced 400 ft. of damaged pipe without the need for sewer replacement excavation.
