Basements in this soil tend to have problems with changes in moisture resulting in clay expanding and contracting causing foundation cracks or water problems.

    All types of foundations can have problems on a site with clay soils. A good engineer, however, should be able to design either type of foundation -- a slab or a basement -- so that the foundation won't crack, heave, or settle.

    If you have any doubts, consult an engineer.
