Substrata’s soil stabilization product was highly effective, and the most affordable on the market. The major issue with getting a consumer to purchase was testing their soil. Unlike several other soil stabilizers on the market, Perma-Zyme’s effectiveness depends on how much clay is in the soil. Now, someone who knows what they’re looking for can just grab a handful of soil, add a little water, and know instantly whether or not the soil has clay. The problem was that most of our customers couldn’t do that, instead they had to send their soil to a geotech firm to get tested, which could take more time away from the sale closing. That’s why we created this test kit. It’s a guided “plasticity test” for soil, walking the customer through how to test their soil by themselves. This project was really fun for me, as it involved a lot of physical testing and illustration.
