The amount of bentonite applied to contaminated soils, in general, was not enough on its improvement despite having decreased the concentration of cadmium in plants.
DamIt™ is an advanced, non-toxic, polymer powder, that will expand and bind with the soil in a dam similar to the way Bentonite works. The benefit of using DamIt™ to reduce soil porosity is that it has a much higher swelling effect than bentonite so smaller quantities need to be used and this significantly reduces freight and handling costs.
