Certain types of soil, for example, sand, are highly porous. As a result, it can adapt to the pressure quickly, and drain the porewater quite easily and quickly. On the other hand, some soils have poor permeability, for example, clay. Such types of soils resist the compression, and the dissipation of the pore water is very slow in this scenario.
