In the years since trenchless sewer line repair was first introduced, the methods and tools used have continued to evolve. Today, the process is much more streamlined and extremely productive overall, which is largely due to the introduction of new tools. The following takes a quick look at the six tools that have revolutionized how pipe repairs are done today.
Horizontal Directional Drills
Designed to be used almost anywhere, horizontal directional drills have essentially eliminated the need for a shovel when performing trenchless sewer line repairs. The drilling is done entirely underground by a professional on the outside. He/ she not only has complete control of the drill, but can direct it in any horizontal direction. It is easy to use, cost effective, and prevents the natural landscaping from being destroyed.
When you are having repairs made, you first have to make certain that the old, damaged piping has been removed. This is where an expander head comes in and plays such an important role. It is placed into your existing pipeline and uses air pressure to push or break through the damaged pipe, which clears the way for the new pipe, which has been conveniently attached to the back of the expander head. Thanks to expander heads, your pipes can be repaired or even completely replaced in a matter of hours, instead of the days it could take in the past.
Pulling Rods and the Hydraulic Power Pack
The pulling rod is what the expander head (and the new piping) is attached to when it is launched into the existing piping through the hole made by the horizontal directional drill. Powered by a hydraulic power pack that is equipped to deliver enough force to keep the expander head moving through the existing, while also ensuring the old pipe is efficiently broke up, the pulling rod temporarily expands the cavity’s diameter to allow the new pipe through.
Thanks to epoxy liners, it is now easier than ever to have your sewer pipes repaired with a material that you can rest assured will withstand the test of time. Epoxy is able to provide the structural strength of new pipes without causing damage to landscaping, sidewalks, or structures. Epoxy liners can be used to repair cement, copper, clay, iron, Orangeburg, PVC, or steel pipes and are able to withstand corrosion, cracking due to changes in the environment, and the intrusion of roots. As an added bonus, epoxy liners can be applied in as little as an hour or two and provide a cost effective solution to a complete replacement.
High Density Polyethylene Pipes (HDPE)
While traditional pipes are made from PVC plastic piping, cast iron, copper, or clay, HDPE is made from a special resin or fiberglass that has a life expectancy that exceeds 50 years and can potentially last more than a century. HDPE pipes are around 3 to 4 times thicker than PVC, which means that there is no need to worry about roots or rocks invading your line or a potential pipe rupture or leakage. If your current pipes are beyond repair, HDPE is likely your best replacement option.
These awesome tools have made pipe repairs a breeze so home owners can now sit tension-free staring at their capula while their sewer repair company fixes the pipes of their home without any digging.
