What's a Geothermal Helical Pile?
A geothermal helical pile combines the unique properties of a helical foundation with the efficient and environmentally-friendly power of geothermal heating.
The result is that a structure can be heated and cooled entirely (or nearly entirely) by geothermal for less cost than a typical geothermal setup.
It eliminates the usual boreholing work that needs to be done to install geothermal loops and reduces time-to-install.
Geothermal helical piles leverage the unique properties of a helical foundation to install geothermal loops more efficiently
Typical geothermal heating systems are installed, in part, by drilling boreholes into the earth and inserting the pipe that will create a geothermal loop.
Helical piles are a deep foundation solution that uses a helix plate welded to a hollow steel pipe. The helix plate allows the pile to turn down into the ground like a large screw, and they're typically installed anywhere from 25 to 60+ feet deep.
Because the shaft of a helical pile is hollow and (usually) extends far into the ground, it's an ideal location for a geothermal loop.
Instead of installing the geothermal pipes into boreholes, they're run down the hollow shaft of the helical pile and emerge just at the top. Grout is then added to maximize thermal conductivity.
Because the helical pile shafts are used to install the geothermal loops, it eliminates (or at least dramatically reduces) the need to drill boreholes. This saves on the cost of hauling additional machines to site and the labor for drilling.
Typical geothermal systems are installed outside the footprint of the structure. This can restrict future construction as it's forced to "build around" geothermal infrastructure. With geothermal helical piles, the footprint does not extend beyond the structure.
Highly adaptable and customizable, geothermal helical piles can be used for slab on grade, ICF, beam, and other foundation configurations. Able to be installed in a wide variety of ground conditions with high load capacities, they're ideal for residential or commercial structures.
Easy To Install
Geothermal helical piles are easier and faster to install than other foundations and eliminate the need for additional boreholing. This can save weeks of time compared to a traditional foundation and geothermal heating installation.
Many foundation solutions have a large impact on the environment, from extensive excavation to the reliance on mass amounts of carbon-intensive materials. Geothermal helical piles are made entirely from steel, require no excavation, and can eventually be removed and recycled.
Thermal performance on geothermal helical piles can outperform typical concrete columns, due in part to the steel shaft providing excellent heat retention. In one of our installations, just six geothermal piles were able to supply 100% of the heating and cooling for a 1,560 square foot home.
