Hydro Excavation VS Auger

Jun 25, 2021 | Home Maintenance

Augers are handheld or machine-powered tools used for boring holes through surfaces like soil, wood, ice, stone, rock or pavement. You can use these tools for a wide variety of applications from digging a mere hole in soil, to drilling deep into the earth through shale rock, to boring a hole in ice. Large augers are used to bore holes in soil for the placement of fence posts, telephone poles, and much more.

Augers have a helical screw blade called a flighting that acts as a conveyor, causing debris to move up and out of the newly drilled hole as the blade is rotated.

Using an auger is an efficient way of boring holes, it is fast, strong and cost efficient. When using an auger you cannot see what is below the dirt, as a result gas lines, pipes and other important assets can be struck, thus becoming a safety hazard and very expensive to repair.

Imagine a man using an auger to drill 4-ft deep holes into the ground. During this time, the auger stuttered, and in a lucky turn, the man stopped the drill to check if he hit a rock. Closer examination revealed that it wasn’t a rock; it was a gas line going right through his backyard.

Hydro Excavation

Hydro Excavation is the process of excavating soil with pressurised water and then using a vacuum to transfer the material into a debris tank. The high-pressure water cuts through & breaks up the soil, this will create a slurry. The vacuum is then able to lift the slurry from the excavation area and the material is transferred to the debris tank.

Contractors discovered that using hydro-excavation with water during cold weather or drought was an effective alternative. This is because during tough climate seasons, the ground is firmer and less easy to dig, which is harder to excavate using traditional mechanical means.

Using hydro excavation avoids damage to underground pipes, lines and cables. This in turn eliminates the high expenses needed for repairs and restoration. Needing to do fewer repairs means more time to get the job done!

Hydro excavation equipment needs a vacuum source. There are two choices for this, a fan system or a positive displacement blower. A displacement blower is able to move air in longer distances than the fan system. This means excavation can be done at greater depths.

Our vacuum system consists of a 4” Tri-lobe positive displacement blower, pressure gauge and relief valve, our EnduroVac provides up to 15Hg vacuum pressure. Make your job quicker and easier with equipment powered by your choice of a Petrol or Diesel electric key-start engine, also featuring three-stage filtration with a cyclone separator.

Spend less time emptying your debris tank with the ease of operation. Our 400L tanks are mounted with a hydraulic pump jack and the 850L & 1000L tanks are equipped with cylinder hydraulic tipping and hydraulic opening door.

The Benefits:

  • Safe and cost-effective for service locations
  • Minimised risk of damage to sewer, gas, storm water, telecommunications and underground power
  • Confidence that your project can proceed according to schedule
  • Time saving and compiles with worksite safety
  • Reduces environmental impact with minimal surface disruption
  • Reduced downtime associated with offsite slurry removal and disposal

The EnduroVac is the largest of all gutter vacuum systems on the market, guaranteeing high power and performance. When combined with our large capacity tanks, your job capabilities are endless!
