What is the primary concern when designing foundations in clayey soils?

Step 1: Understand what clayey soils are. They are soils that contain a high percentage of clay particles.
Step 2: Learn about compressibility. This means how much the soil can be compressed or squished under weight.
Step 3: Recognize that clayey soils can compress a lot when heavy structures are built on them.
Step 4: Realize that this compression can cause the ground to settle unevenly over time.
Step 5: Understand that this uneven settling can damage buildings and structures.
Step 6: Conclude that the primary concern in foundation design for clayey soils is to manage this high compressibility and prevent excessive settlement.
