Warning: Rocks, roots, or a weak impact wrench (we recommend a corded 350 ft-lbs DeWalt) may prevent you from driving the auger fully into the soil. Use only a 6 point socket as a 12 point socket may strip the driver head. To test your soil for auger suitability, use a 3/4" spade bit with a 24" bit extender and try driving it into your soil. This will give you a good indication of this system will work in your location.

Pull out resistance (tension) from undisturbed soil varies by soil type and auger length.  If you are building a project where known uplift data is required please see our Tension Test data for sandy or clay soils based on auger length.  This is data taken from field testing by Intertek in a location in Colorado and is part of an extensive residential code compliance review program this is expected to be completed in the spring of 2022.
