Tree Root Infiltration and CIPP

sewer-line-blockageWe are experienced with working with piping in all sectors, from residential homes to large industrial facilities. But all sewer line pipes are vulnerable to similar problems, no matter the size of the facility. Corrosion, blockages, and breakage are all frequent. One of the most common troubles we’re called to deal with is tree root infiltration. In fact, almost 50% of all sewer blockages and backups are because of tree roots growing into the line.

Why Tree Roots Create Such Problems

Tree roots grow in the direction of loose soil since this soil is the least resistant to the roots’ movements. The soil around sewer lines is often loose because of the placement of the pipe, so tree roots are already inclined to move toward the sewer line. The water and nutrients inside the sewer line further attract root growth.

Older pipes are more susceptible to the problem because they can develop leaks and cracks. When sewage leaks out, roots will move that direction and can then infiltrate through the openings and enter the pipe. We recommend facilities with old clay or cast iron pipes to have the entire sewer line replaced—especially if the line runs through an area near trees.

Proper landscaping can help keep away the danger of fast-growing tree roots reaching sewer lines. However, this may not be an option for your home or facility. When you start to encounter sewer drainage problems, schedule service with our technicians to inspect the inline and find out if root infiltration is the trouble.

Repairing Tree Root Infiltration Into a Sewer Line

There are a few different methods that can be used to eliminate tree roots in sewer lines. The inspection tools we use will help us understand the problem and make the best choice about how to deal with it. Simple root infiltration can sometimes be fixed with chemicals or with augers but down the line. But often, we have to take larger measures to not only get rid of the roots but fix the damaged pipe as well.

This is when we’ll use CIPP repair in Seattle, WA. CIPP stands for cured-in-place piping, and it’s one of the most useful tools for lateral pipe repairs. The basics of CIPP is to insert a new pipe within the older one, which is then carried through the old pipe and sealed with epoxy along the interior to create a new pipe surface.

To handle tree roots with CIPP, we first use a hydro-jetter to blast away the roots that are already inside the sewer line. This clears out the pipe interior. Then, we send in the pipe liner to the area of the infiltration and seal off the section. This not only closes off the breaches from the roots, but it stops the roots from finding a way back in. How? CIPP is seamless, so there are no joints for the roots to burrow through. CIPP is a permanent solution to the problem, and the new pipe material can last for more than fifty years.
