What is a concrete floating slab?

A concrete floating slab is a slab that is not anchored to the ground but instead merely sits on top of it. Floating concrete slabs provide solid foundations for structures as sheds, garages, home additions, and even manufactured homes.

The primary benefit of a floating slab is that it's easier and less expensive to build than a standard foundation. Whereas a standard foundation consists of strip footings poured several feet below the ground's surface, and a frost wall constructed above the ground's surface, the floating slab literally floats on the ground. Less ground preparation is needed, and the cement-pouring process is much simpler.
