What is Trenchless Sewer Repair?
Trenchless Sewer Repair is as effective as traditional sewer line replacement options. There are some differences for trenchless sewer repairs from the type of pipe material available, or even to the techniques from plumbers who only offer one service of pipe bursting or pipelining.
Trenchless Sewer Repair Vs. Traditional Trenching Sewer Repair?
Trenchless Sewer Repair can be more expensive than the traditional option of trenched sewer line replacement.
Traditional trenching methods involve digging long trenches in your yard to remove and lay a new sewer line pipe.
The process may alter your landscaping, driveways and other ground areas near the area where your trench is.
Most Traditional trenching jobs can cost 15-20K or more depending on the amount of digging and construction supplies needed.
On top of that, this process also usually involves getting approvals from the government, traffic control (rerouting), or the area that may need to be cut off for this type of repair along with permits.
Trenchless sewer replacement is a newer alternative. While it been around for about 20 years, a lot of homeowners are still not aware of this option yet.
The most frequent types of trenchless sewer line replacement are:
A flexible tube coated with a resin that is pulled or blown into the problem pipe and then inflated as a pipe liner. As the resin hardens it creates a strong pipe tube within the existing pipe. One major benefit of this type of pipe repair makes it joint-free and also corrosion resistant. Pipelining is a process of forming a new hardened seamless plastic pipe inside the old pipe.
Pipe bursting is another trenchless sewer replacement method that uses a large cone shape head is usually hydraulically pulled by steel cable through the old sewer line, thereby breaking apart the old pipe underground while at the same time pulling into place a seamless HDPE pipe that is the same size or even larger than the old pipe.
Costs vary, depending on different factors for trenchless replacement such as:
• Type of Trenchless Sewer Replacement Option Used
• Length of digging required to reach sewer line
• Type of soil
• Price for materials
