Slab-on-grade foundation is used when the structure is built directly on the ground. Monolithic slab-on-grade foundations require a wide base and steel reinforcement. A floating slab is a reinforced slab placed between two walls and footings. Aside from the usual defects (cracking, seepage) the inspector will be looking for, slab foundations are more susceptible to termites and other insects. Slab homes are difficult to inspect because almost all of the entire structure is enclosed and not visible. Other areas will be inspected more carefully for indications of problems related to slab-type construction.
