What Is Trenchless Pipe Bursting?
Pipe bursting is a trenchless sewer repair method that involves breaking and expanding the existing buried sewer line while simultaneously replacing it with new high-density polyethylene pipe.
What Equipment is Used for a Pipe Bursting Sewer Line Replacement?
Pipe bursting is accomplished by pulling an expander head (also known as a “bursting head” or a “bullet”) through the old pipe. The head is small enough to fit through the existing pipe, and it fractures the existing pipe as it is pulled through.
The back of the head is connected to new pipe, which it drags and places behind it.
What lines can be repaired or replaced using this method:
- Water Main Lines
- Sewer Main Lines
- Storm Drain Systems
- Conduit Lines
What Is The Process?
Measurements: are taken and an entry point and exit point are excavated to the proper depth.
The pipe bursting process uses a cone-shaped bursting head that’s larger than the new replacement pipe, through the existing pipe. Pushing this down the existing pipe results in the splitting of the pipe. As the bursting head is pulled through the host pipe, the fragments create a void for the new pipe. The new pipe immediately follows the bursting head as it is simultaneously pulled or pushed into the newly formed cavity. With trenchless pipe bursting, you don’t have to destroy your yard anymore! The replacement pipes last up to fifty years or longer.
What Are the Benefits Of Pipe Bursting?
• Avoids damage to landscaping and hardscaping such as fences, gutters, sidewalks, decks, driveways etc.
• Shorter completion time
• Provides a safer work environment
• In most cases, it is more cost effective
