Frequently Asked Questions
What exactly is "pipe bursting," and how does it replace the old sewer line?
Pipe bursting is a trenchless method used to replace a damaged sewer pipe without digging a lengthy trench. The process involves inserting a specialized conical bursting head into the old pipe. As the head is pulled through using a powerful hydraulic system, it fractures the existing pipe outward into the surrounding soil. Simultaneously, a new, joint-free pipe (typically High-Density Polyethylene, or HDPE) is pulled directly behind the bursting head, immediately taking the place of the old line.
How many access points are required for a trenchless sewer replacement?
A trenchless replacement using the pipe bursting method requires only two small access points to complete the entire job. One access pit (the "launch pit") is dug at the beginning of the damaged pipe section, and a second pit (the "receiving pit") is dug at the end of the run. These pits are used to insert the equipment and the new pipe and to make the final connections to the system. This minimal excavation is what prevents damage to the rest of the property.
Can trenchless pipe bursting be used on any type of old pipe material?
Pipe bursting is highly versatile and can be used on most common sewer pipe materials, including clay, cast iron, PVC, and Orangeburg. The method works by breaking the rigid or deteriorating old pipe apart. However, the successful application of pipe bursting depends on the severity of the damage; it cannot be used if the existing line has extreme misalignment or if the soil conditions are highly compacted or rocky.
Does this method completely remove the old, collapsed pipe?
No, the pipe bursting method does not remove the old pipe from the ground. Instead, the conical bursting head breaks the old pipe material (such as clay or cast iron) into small fragments and pushes those fragments outward into the surrounding soil. The new pipe is then immediately pulled into the newly created void. The fragments of the old pipe remain harmlessly buried in the trench line.
What are the main benefits of choosing trenchless replacement over traditional excavation?
The main benefits of choosing trenchless pipe bursting are centered on minimizing property damage and project time. The key advantages include:
Minimal Disruption: Only two small pits are dug, saving driveways, sidewalks, and extensive landscaping.
Faster Completion: Most replacement jobs are completed in one to two days, significantly faster than traditional trenching.
Superior Quality: The new pipe is seamless (joint-free), highly resistant to root intrusion, and has a very long projected lifespan.
Is trenchless replacement more expensive than digging up the yard?
While the specialized equipment and materials for the trenchless process can sometimes result in a higher initial price for the pipe installation itself, it is often less expensive overall. Traditional excavation requires a much higher total cost due to the labor, equipment, and extensive fees required to repair or replace concrete, asphalt, and landscaping after the trench is filled in. Trenchless methods eliminate most of these large, hidden restoration costs.
