In a very small site we used our limited access drill to bore 5—150’ holes for a geothermal heat pump. This drill can be utilized in mud and air rotary as well as hollow stem auger. It has a tested maximum depth of 300’. Will it go deeper….don’t know yet.
Here are some of our recent projects
This is a water well rehabilitation job in Manassas Virginia. The original well had collapsed and needed to be cleaned out and deepened. We utilized our limited access “Berretta” drill for this effort because of the inability to move a large drilling rig on the site.
One of many thermal conductivity tests we have run to test the formations ability to absorb heat energy. This job was in Loudoun County, VA.
Example of butt fusing HDPE large supply and return lines. This installation was for the National Guard in Winchester, VA
Installation of Rehau’s Raugeo four probe geothermal loop in Winchester, VA. This pipe has no fusion joints down the borehole and utilizing 4 pipes gives 15% to 20% more efficiency.
Preparing a loop for one of several VDOT geothermal jobs.
Preparing the concrete header vault for 50 geothermal loops. The tarp is only used to work during the rain. This installation was for the National Guard in Winchester, VA
We just had enough room to use our large drill to install 2—300’ wells for this “Green Home” built in Arlington, VA
Drilling a Thermal Conductivity bore hole for a Middle School in Rockbridge County, VA. We utilized a sediment bag to contain the “rock cuttings”.
This was the first commercial job in the USA to header a geothermal job using Rehau’s probalance manifold. The manifolds give the ability to perfectly match the flow from loop to loop as well as isolate as failed loop in the rare case it happens. This installation was for the National Guard in Winchester, VA
