American Ground Screw and IronRidge Systems

American Ground Screw is excited to have its 3” and 4” ground screw products tested and included as an engineered foundation option for IronRidge’s 2” and 3” rigid pipe racking systems. Adding our screws to their online Design Assistant as an alternative to concrete reflects not only IronRidge’s confidence in the quality of AGS’s products but that ground screws should now be considered as a true replacement for concrete for all installers, whether experienced with ground screws or not.

Ground screws offer the following advantages for ground mount solar installations:

Work best in dense, very dense, very stiff, and hard soils;
Ideal for rock, where the design is often based on yield strength as opposed to cohesion;
No digging or soil removal needed;
Immediately loadable, no need to wait for curing.

Ground screws offer the following sustainability advantages as well:

97.5% less embedded carbon than concrete needed for similar performance;
Warrantied for 25 years, but have 50+ year lifecycle;
Screws can be reused or recycled at any time.

Installation

Ground screws are easy to install with either machine-mounted hydraulic or handheld electric driver.

Do you need to pull a permit?(Required)

Yes

Yes - Since you plan to apply for a permit, I would start by asking your local code official if they will accept the use of ground screws. If they require it is building code approved or have additional questions, I would encourage you to share our ICC evaluation report(hyperlink) with them. American Ground Screw is the first company to have ground screws accepted into the building code, however, because it is such a new technology in the U.S. each jurisdiction views them differently. You can review the load capacities on page 11, table 5 to see if they meet your requirements.

No - American Ground Screw is the first company to have ground screws accepted into the building code, and the attached ESR documents that approval. I understand you are not going to submit for a permit, but you can review the load capacities in the chart below to see if they meet your requirements.

Do you have access to a low-speed/high torque auger?(Required)

Yes

(Commercial-grade ground screws require low speed/high torque equipment to install. We offer a hand-held electric driver as well as a machine-mounted hydraulic unit for sale and rent. You can view them on our website under information/installation.
