Expansive soil can swell up to 10-15% of its dry volume and as it expands, it will caused bowed foundation walls or foundation heave if it is pushing up against your foundation floor.
This soil can just as dangerous for your foundation in the dry seasons because it shrinks as it loses moisture. Your foundation will suffer from decreased support and cracks will begin to form. These cracks let water into your foundation and weaken the structure. This cycle of expanding and shrinking can lead to foundation settlement or other types of serious damage.
