What is the primary concern when designing a foundation on expansive clay in a case study?

Step 1: Understand what expansive clay is. It is a type of soil that can change its volume significantly when it gets wet or dry.
Step 2: Recognize that when it rains, expansive clay absorbs water and swells, and when it dries, it shrinks.
Step 3: Identify the problem: This swelling and shrinking can cause the ground to move, which can damage buildings and structures.
Step 4: Consider the primary concern for foundation design: ensuring that the foundation can handle the movement of the soil without cracking or settling unevenly.
Step 5: Think about solutions: Engineers may need to use special techniques or materials to create a stable foundation on expansive clay.
