What Is Trenchless Pipe Lining and How Does It Work

Sometimes, sewer line repairs require digging through a large section of a homeowner's yard to reach the pipeline. The process can result in high costs in terms of restoring the yard to its former condition. However, trenchless pipe lining can prevent a mess and ensuing costs. But how does it work?

This article will explain the basics of trenchless pipe lining and how professionals perform the job.

What is trenchless pipe lining?

Unlike the conventional method that consisted of digging a large hole, trenchless pipe lining includes digging just a small pit at both ends of the pipe. As a result, technicians can determine the damage's scope and recommend the best course of action without extensive damage to the yard.

How does trenchless pipe lining work?

The first step is to dig a small access pit at both ends of the pipe. The technicians then insert a flexible tube with resin into the existing sewer pipe and blow compressed air into the pocket to force the tube against the pipe's inside walls.

Once the resin hardens after a few hours, it creates a solid pipe within the old one that looks almost the same as a PVC pipe. The new pipe's diameter will be slightly reduced, but it will still be smooth and impenetrable by roots.

However, this pipe relining method may not work if the old pipe's sections have collapsed or become offset from each other.

Does trenchless pipe lining harm trees?

Trenchless pipe relining and pipe bursting don't pose a threat to trees in the way, so there's no need to cut them down. The trees won't be affected by the procedure and will remain intact.

How much does trenchless pipe lining cost?

Relining damaged sewer or lateral pipes typically costs around $80 to $250 per foot. In total, the cost of relining a standard sewer line can go anywhere from $4,000 to $20,000, depending on the circumstances. However, most homeowners pay somewhere between $6,000 and $12,000 for repairing critical sewer connections.

Conventional pipe repairs start at a lower price (about $50 per foot). However, the total cost can be much higher because traditional jobs require higher labor costs, road closure, and additional landscaping costs.

As a result, there are many cases where trenchless pipe lining is the better alternative. For example, if a damaged pipe lies under a driveway, sidewalks, or large trees, trenchless pipe relining can save up to $10,000 in repair expenses.

Save yourself a lot of hassle

If the circumstances allow it, there's no reason not to go for trenchless pipe lining. The method will leave the yard and the surroundings almost unscathed and won't take a massive toll on the budget after the job is over.
