How Soil Destroys Buildings

3-Second Blueprint (English)

1. Expansive clay minerals absorb water between molecular layers to swell when wet and shrink as they dry, shifting ground volume beneath slabs.
2. Structural damage stems from differential movement when slab perimeters dry out or localized pipe leaks swell soil unevenly under a load.
3. Oedometer confinement tests demonstrate that hydrating clays generate immense upward swell pressure capable of heaving heavy foundations.
