Perma-Zyme binds soil into a concrete-like surface up to 10 times stronger than untreated soil. Treated soil scored higher than Type II aggregate on r-value tests. With its hard surface, Perma-Zyme lets you use the soil that's already on your jobsite as your subbase—with little to no hauling. It also allows for a thinner chipseal or asphalt topcoat, saving you up to 80% on construction. You will notice a stronger, longer-lasting road.
