Commercial Geothermal

We have been involved in 3 ton to 500 ton vertical geothermal loopfields. Drilling and loopfield installation can be provided in a timely manner to maintain projects schedules. Multiple drill rigs, grouting crews, and installation crews can work to maintain schedules. Our modern air rotary drilling rigs can drill with either state of the art PDC bits or down the hole hammers. All loopfield installation crews are certified by IGSHPA and certified in heat fusion. Dillan’s works with many of the leading architects, engineers, building contractors, and mechanical contractors. We have become the leading loopfield contractor in Western Pennsylvania and Eastern Ohio.

Thermal Conductivity Testing

Thermal Conductivity testing is often required to design a geothermal system. Dillan’s can complete the borehole, install geothermal loop and grout the borehole. We work with the country’s leading testing companies to provide test results.
