What is Trenchless Plumbing and What You Need to Know


While wastewater and sewer systems might be the last thing that crosses your mind, getting them repaired is essential, particularly when the drainage pipes end up cracking or breaking. Whether your home has a septic tank or connects directly to a sewer system, both are connected to a main drain.

This drain is placed underground. And when the plumbing lines present underneath are damaged, you must opt for trenchless plumbing. So, what exactly is trenchless plumbing? Read on to find out!

What is Trenchless Sewer Repair?

Trenchless sewer or pipe repair is a method of repairing damaged pipes without trenching. This repair method is minimally invasive and can effectively make repairs without requiring massive unearthing. It is
also why trenchless repairs have gained such massive popularity in the past few years.

Types of Trenchless Repair Methods

There are quite a few trenchless plumbing solutions. Here are the most common repair methods used:

Pipe Burst Method

With adequate training, the pipe burst method is the simplest technique used for replacement. In this method, the old pipe is expanded and broken. While at the same time, a new pipe takes the place of the existing one.

Typically, a “bursting head” is used, which fractures the existing pipe, and the new pipe is inserted and laid right behind the old one.

Slip Lining

Slip lining is an excellent repair technique that does not require removing your existing pipe. An epoxy liner is added to the sewer line, thus forming a new pipe inside the old one.

Cured-in-Place Lining

The cured-in-place lining is similar to the slip-lining technique, only this one is a bit more complex. This technique uses a resin-saturated liner. The liner is also placed inside the existing pipe. However, it must be expanded and cured upon heat application.
