Trenchless Sewer Pipe Repair & Replacement
Trenchless Water & Gas Pipe Boring * All trenchless projects are subject to inspection and diagnosis, trenchless technology does not work on all projects and you should consult a licensed and trenchless certified plumber to find out if your project is right for trenchless. True Eco-Friendliness Means Facing a Dirty Underground Subject Originally publishined in Bellows Plumbing Newsletter Winter 2008 - Heavy root intrusion and soil movement can cause small cracks in residential sewer lines. Tree roots follow a trail of vapor moisture escaping from small cracks, holes, or poorly sealed joints in your sewer line. Especially during winter or dry seasons when root growth increases; roots can travel hundreds of feet and grow to more than two feet in diameter. Once the roots penetrate these small cracks they continue to grow and exert considerable pressure at the crack or joint. Increased pressure causes the line to crack and collapse, which then requires costly replacement.
Repairing damaged sewer pipes is an important part of keeping our beaches and rivers clean of human waste and bacteria. A damaged sewer line left unchecked can not only contaminate an entire property but can leech affluence and chemicals into the ground water, rivers, and oceans. According to 2004 data from the National Resource Defense Council over 21 Santa Cruz and Monterey County beach closures were due to private residence sewer lateral contamination. Its a common miscomception but a majority of suewage spills are a result of private homeowners. |

A splitting head is attached to the new pipe and hammers the new pipe through the old pipe by splitting and expanding the old pipe. While the old pipe is being expanded the new pipe is simultaneously being pulled through the old pipe. |

The new pipe will follow the same path as the old pipe. However, the new pipe will be a joint-free Polyethelyne replacement that will far outlast the pipe it is replacing. Also, because it is seamless, it doesn't allow roots to penetrate like old jointed sewer pipes do. |
