‘It’s amazing how a project can start off so small and turn into something much larger so quickly!’  That was the conversation starter I used as I greeted Lee Shaw from Geoprobe Systems® when he was here in the lovely State of Wisconsin delivering our new Geoprobe® 7822DT.  But I’m getting ahead of myself.

When Protanic, Inc. contacted us to assist them in drilling, concrete coring and cutting activities for their Cathodic Systems for the long-lasting protection of their client’s underground storage tank site, we had no idea it would result in the volume of business it has. At first we were cautious about spending a lot of money on something we thought would be short lived. But after the first installation project was completed with relatively good success, the obvious question arose ... “How could this be done faster and more efficient while eliminating any environmental concerns, since about 95% of the gas stations had contaminated soils present?”

So that’s what Lee and I discussed before he left Wisconsin. He continued the conversation with Geoprobe® engineers when he got back to Kansas. After the initial discussions were over, the task in front of the engineering team boiled down to: Can large anodes be installed through the DT60 system using a 7822DT and completely remove the complex problem of handling contaminated soils at every one of these stations?

Within days of Lee being back in Kansas, the Geoprobe® team was hard at work. I called them a week later and said I’d like to get this tested for a job the following week. Within a few more days I had a whole bunch of tooling sitting on our door step, some of which I had never seen before! Some of it was existing and some of it was custom made, specifically for these projects. We were absolutely floored at the speed at which this was executed by the Geoprobe® team!

Not only was Protanic amazed at the brand new 7822DT rig that we just showed up with, but also the fact that we had taken the time to work with Team Geoprobe® to develop new tooling just for them.


Benefits From Using Geoprobe® 7822DT:

  1. Concrete coring completed with 7822DT and Geoprobe® coring system with a much smaller diameter core required.
  2. No need to switch rig over to auger capabilities.
  3. Zero contaminated soil handling.
  4. Speed at which borehole depth was reached was outstanding.
  5. No need to clean augers ... didn’t use them.
  6. Minimal concrete patching and cleanup.

Because of this, we were then able to install anodes in about 30 minutes, from start to completion, as opposed to the HSA auger method with cleanup that took around 2 hours per anode, not to mention that certain sites required larger anodes and 6.25 in. ID augers for installation. The time savings has been remarkable! We simply cannot describe the full impact this has had, and will continue to have, on our business.

After owning the 7822DT for only a week, the power, finesse, and the rig’s all-around capabilities have just blown us away! We were so impressed with the Geoprobe® team; they even flew up to Wisconsin and spent the day with us on training.

Our overall success is dependent on our client’s success. This joint effort with Geoprobe® resulted in a continued business relationship, multiple projects, and jobs for many hard-working employees. When Lee contacted me later to ask, “Well, how did it go?”, all I could say was, “Amazing!”
