A 4m thick layer normally consolidated clay has average e = 1.3. Its compression index is %3D 0.6 and coefficient of consolidation is 1m²/yr. If the increase in vertical pressure due to foundation load on the une clay layer is equal to existing effective overburden pressure, the change in the thickness of the clay layer is mm.
