"SUPERSOL" acts on the clay particles in the soil, ionizes them and reverse permanently their polarity changing a water adsorbent clay particle in a water repellent treated clay particle. By treating a layer of 15 to 20 cm of soil with "SUPERSOL" Soil Stabilizer, you can achieve the required density from soil that is normally discarded. There is no need to strip and haul this material away. The treated soil will give high compaction, high density, high CBR to a point that this layer of 20 cm will give a strength equivalent and often far superior to a conventional sub grade, sub base and base combined
