The Benefits of a Pipe Lining

Published On February 2, 2019 | By Clare Louise | Safety & Security

If you live in New England, you know how hard winters can be on both pipes and sewers. Water and metal are constantly expanding and contracting, and the ravages of frost heave can leave you with a burst sewer line. Trenchless pipe replacement is a less intensive and cheaper way of fixing sewer pipe problems, and a trenchless pipe lining is the easiest method of all.

How trenchless pipe replacement works

In the past, repairing a sewer line that runs under your yard would have meant digging down to reach the pipes. Trenchless pipe replacement is a way of avoiding all this. There are three types of trenchless pipe replacement, and the right method for any project depends on your specific situation.

Pipe bursting

In pipe bursting, your plumbers will dig a small hole at the beginning and end of your existing line. They will then push through your existing pipeline with a “bursting head.” This head shoves the old pipe apart and out of the way.

At the same time, the bursting head drags a new pipe behind it into the correct place. The new pipe is usually made of PVC.

Directional drilling

This method requires digging a whole new tunnel for your pipes. This tunnel goes underneath the existing pipe and usually has to be done when there’s no way of replacing or repairing the pipes, or if the repair would be too expensive to do.

The good news is that with this method you still don’t have to tear up the whole yard. A directional drilling machine can move horizontally after boring into the ground in just one place.

Pipe lining

Sewer pipe lining is the newest and fastest trenchless method of replacing your sewer line. It takes a plumber certified in pipe lining to do the job, but there are many benefits to using this method.

In a pipe lining, your plumbers will simply thread a liner through the existing pipe. This liner is usually made of fiberglass. After the liner is inflated, it will cure in place and give you a pipe within your existing pipe.

What are the benefits of a pipe lining?

A trenchless pipe lining offers quite a few benefits over other methods of fixing or replacing your pipes, including other trenchless methods.

Save some time

A pipe lining is extremely fast. Because there is no need to dig up your yard or take down walls to reach pipes, the whole process can be done in a day or two, and sometimes in just a few hours. With a traditional pipe replacement, the whole project can take weeks.

Preserve your landscape

With any traditional method of replacing a sewer pipe, you will have to dig up your yard and possibly some of the driveway or sidewalk. Depending on where your sewer joins the main line, you might even need to get city permits and block off parts of the street.

With a pipe lining, you can avoid all these issues, as well as the time and logistics nightmare that digging a trench can present.

Spend less money

A pipe lining is much less expensive than digging into the yard to replace the pipe, and it is also cheaper than pipe bursting and directional drilling. Because it takes less time you pay for fewer man-hours of labor, and since you don’t tear up your yard, you don’t have to pay to have the landscaping redone.

Save angst

One of the worst things about having a sewer pipe replaced is the way the process interferes with your schedule and lifestyle. With a pipe lining, you don’t have a worry about people tramping around for days on end, disrupting your family life.
