Trenchless Pipe Replacement: Underground Pipe Replacement With Minimal Digging
By Juanita Swindell
The drain pipe that runs beneath the ground if often subjected to several harsh elements without us being aware of it. While you can insulate the pipes inside homes to ensure they do not freeze up during winters, the ones that run underground are often neglected as we are unable to see them. However, they are also constantly in contact with underground water, mud and several other chemicals found beneath the surface. This makes them exceptionally susceptible to early rusting which can make them brittle and cause breakages.
Getting the underground pipe replaced used to be a real nightmare. Replacement often involved extensive digging of the gardens, driveways and everything else that was found over the area where they lay. However, this inconvenience has now become a thing of the past thanks to trenchless pipe replacement.
What Is Trenchless Pipe Replacement?
As the name suggests, it involves underground pipe replacement that is accomplished without digging long trenches in the ground. If you feel this is the name given to some kind of glorified drain repair that would clog up again in a few months after the whole process then you are going to be pleasantly surprised. This is a process that actually involves a new pipe installation underground. However it is accomplished without extended digging, as the new pipe is run through the old one.
How Is It Accomplished?
It is accomplished by the means of a heavy duty pulling unit, pulling cable and a brand new underground pipe. Two small pits are dug at the starting as well the ending points of the region where the relining needs to be done. A new pipe is fed through the entry pit while the exit pit has a pulling unit installed that is capable of pulling great loads. A pulling cable that is run through the new pipe and a cone breaker is fed through the entry pit to the exit pit where it is attached to the pulling machinery. The cone breaker is used to blast through any clogs in the old pipe and the new one is then pulled using the cable through the old existing line.
What Are the Advantages?
Drain repair is a great option for an underground drain, however there comes a time when no amount of repairing can get the job done and a replacement becomes imperative. This is where this new technique really helps in getting the job done with minimal disturbance.
The technique is also a highly economical preposition and the total cost incurred actually comes out cheaper when using this trenchless method as addition overheads of rebuilding lawns and driveways are easily avoided. The extensive disruption of day to day activities also does not occur as this is a fairly fast process which is accomplished by digging just two 24 by 36 inch pits.
The next time you encounter a clogged or corrugated underground pipe, fear not the plumbing repair work is going to be a breeze with the modern no dig technology.
