(February 2017) A concrete slab is a common structural element of modern buildings.

What is a floating slab? A floating slab is a concrete slab foundation on which a structure is built. A floating slab does not have frost protected footing and is designed to âfloatâ with the ground during the winter months. Floating slabs are most commonly used when building a detached garage or shed. A floating slab cannot be used if the structure that is built upon it is attached to your house. In this case you will need frost protected footings and a block foundation.
