Blend of natural occurring microbes which react with the clay particles producing a natural polymer that replaces the water and air voids between the clay platelets, significantly reducing the clay's ability to absorb moisture. One of the significant benefits of this microbial action, is the microbes ability to move down through the profile past the treated depth and in some cases up to 240 mm deep into the substrate. 20 litre plastic container approximately 20.5 kg.
