great product.. unfortunately you can't use them under 'conditioned' spaces in Wisconsin... 'just' found this out. They work great for decks though.
Fascinating. So many good uses for these. Depth of pins is related to frost depth? This solves so many problems where we can’t get a rig in for helical piers… what’s the rationale wrt conditioned spaces? Can’t you just tell them it’s a shampoo only job?

I’m more interested in your Sputnik foundations?! What are they called?

Yes...

When asked, the plan reviewer didn't even know...
Wisconsin's product evaluation doesn't give much hint either: https://hub.openingdesign.com/OpeningDesign/OD_Library/src/branch/master/Code/Uniform Dwelling Code (Wisconsin Residential Code)/Product Evaluations/Diamond Pier - Wisconsin Building Product Evaluation.pdf
