WebClay is cohesive and can have a high variability in plasticity, depending on the mineralogy of the clay particles present. Clay represents particles smaller than 0.002 mm, or 2 microns (µm) in a soil sample. The cohesion of a clay soil is an indication of its strength, and softer clay soils are characterized by a lower cohesion or lower strength.
