Question: Why won’t you build my garage on a floating slab foundation?
Answer: A floating slab foundation is a foundation which doesn’t have concrete footings. This allows for the garage floor to just be poured over gravel and the existing ground. The problem with this is that we live in a climate which has freezing and thawing conditions. When the ground freezes it can lift the foundation as the earth expands and then when it thaws it settles back in its original location. This movement can cause the structure to be damaged. It also can create cracks and possibly it will not settle back in its level position. As a result, when we build a garage, we always build on a foundation which has footers which are poured at least 38” below the finish grade. This avoids being concerned with the freezing and thawing process.
