Trenchless Excavation

With all the varied methods of excavation out there, it's important that you know your options, and choose the best method for you and your project. If you are planning on installing irrigation, sewer lines, or the like, perhaps the best method of excavation available to you is trenchless excavation. Let's find out why!

Why Go Trenchless?

  1. No landscape destruction. Let's face it, digging ditches the traditional way, or even using more advanced methods like vacuum excavation can work just fine, but if aesthetics are a primary concern of yours, you might not WANT what is essentially a giant scar running the length of your project site. Yes, you can plant grass or flowers, but that takes time. Trenchless excavation uses only two points - an entry and an exit, so any "scarring" is minimal.
  2. Reduced cost. This one really needs no explanation, but here it is: If you use trenchless excavation, chances are (though there are always exceptions) good that your project will come in under budget. It's simple economics: Trenchless excavation requires less work, and less work means less money coming out of your wallet.
  3. Better structural integrity, little or no intrusion from the root systems of surrounding flora, and increased flow capacity. Traditionally, piping placed in trenches dug the traditional way had to do its job while contending with competition from the environment, as well as structural issues arising from within the trench it was housed. Trenchless technology, on the other hand, has led to the creation of an entirely new form of piping / structural reinforcement. Using epoxy resins, this new form of pipe can be built inside the trench, and "pulled" along its length. This lends structural strength to the entire trench and negates the need for large, open ditches simultaneously. Another closely related method is to simply repair / reinforce the site in need of work, rather than the entire course of the trenchless area.

There are essentially three steps in the trenchless excavation process:

  • First the line(s) to be worked on are evaluated, usually with the aid cameras.
  • Lines are cleared of any obstructions, and the "interior pipe" / lining product is pulled into place, either along the entire length of the "trench", or simply at the effected area.
  • What you end up with as a result of the trenchless excavation method is a sort of 'pipe within a pipe", seamless in nature, and nearly impervious to root interference or decay from dampness or other environmental factors.

While this process might sound difficult or super advanced, the entire process takes place above ground, which means the landscape surrounding the excavation site will remain undisturbed. If you're interested in trenchless excavation, call an excavation contractor today!
