Chen outlines several methods to mitigate the risks of building on unstable ground: Drilled Pier Foundations

Expansive soils—often called "shrink-swell" soils—are one of the most costly and widespread geological hazards in the world. From the vertisols of Texas and Australia to the black cotton soils of India and the marls of Spain, these clays change volume dramatically with moisture fluctuations. When they absorb water, they swell; when they dry, they shrink. The resulting ground movement can crack foundations, warp slabs, and rupture underground utilities with a force that exceeds the weight capacity of most buildings. foundations on expansive soils chen pdf

Perhaps the most technical chapter involves calculating total and differential heave. Chen outlines the method of summing the swell of discrete layers within the active zone. Chen outlines several methods to mitigate the risks

In the world of geotechnical engineering, few materials inspire as much caution as expansive soil. Often dubbed the "silent destroyer," these soils are responsible for billions of dollars in damages annually—often exceeding the cumulative damage caused by earthquakes, floods, and hurricanes combined. The resulting ground movement can crack foundations, warp
