Trenchless Sewer Pipe Bursting – Sewer Pipe Bursting is a method of trenchless sewer repair that requires very little digging. Two small access holes are dug at each end of the existing sewer line. A cable is inserted at one end and fed through the existing sewer pipe to the other end and attached to the front of a cone shaped tool called a bursting head.
The bursting head is securely fastened to a brand new high grade polyethylene sewer pipe. Using a very powerful hydraulic winch, the bursting head is pulled through the existing sewer line easily breaking it up while towing the new pipe in behind it. The result is a brand new seamless sewer line that is highly resistant to root intrusion, water infiltration. This material is “highly resistant to corrosion and degradation, recent studies conclude it will last at least 100 years.” (Quote from the JM Eagle website.) The project is usually complete in 2-3 days with the customer being inconvenienced for only a couple of hours during the pulling process.
No matter what you are told, over 90% of sewer laterals can be replaced using pipe bursting. Minor rises and dips in the later will be pulled out during the pulling process., and as long as there is at least a 1” diameter hole in the existing pipe, we can burst a new sewer.
This process can be employed when replacing a 4” line with a 4” line or a 6” line with a 6” line. We can also upsize a 3” line to a 4” or a 4” to a 6”, all without excavating trenches that will ruin your landscaping and hardscapes.
