We took our many years of drilling expertise and applied to the geothermal industry. We are licensed water well contractors in Illinois, Wisconsin, Iowa, and Indiana. We have been drilling wells of all types for over 50 years and have all the equipment and expertise to accomplish projects of any size. Many in the city of Chicago. We specialize in the process of geothermal drilling and grouting.   

Generally a geothermal well is drilled from the range of 150’-400’ depending on the tonnage needed and soil conditions. Once the total depth is reached, a HDPE loop is installed in the bore hole. An HDPE loop is a type of plastic pipe that is designed and guaranteed to last 50 years by the manufacturer. The well is then back filled from the bottom to the top with a thermal conductive grout designed to enhance the heat transfer from the HDPE loop to the earth.  The depth and number of loops depends on several factors including the soil conditions and tonnage needed.

Once the drilling process is complete, the header tie-in begins. A trench
is dug (below the frost line) and all the loops in the well field are
tied together. The loops are connected to the header pipe by
heat fusion which is done by our IGSHPA certified fusion
specialists. The header pipes are then brought into
the building and the trenches are backfilled.
