Do slab foundations have footings?
Learn more about Slab Floor Foundations
Slab foundations typically include footings, although they may be incorporated into the slab in a different way than in foundations with basements or crawl spaces.
Each of these types of foundations—slab-on-grade, T-shaped, and frost-protected slab foundations—incorporates footings, but they do so in different ways tailored to their specific purposes and environmental needs.

Slab-on-Grade Foundations
Slab-on-grade foundations can be either monolithic or stem wall. In a **monolithic slab-on-grade foundation**, the slab and the footings are poured at the same time, with the perimeter of the slab being thicker to form an integral footing. This thickened edge provides the necessary support for the structure's walls. In a **stem wall slab-on-grade foundation**, a footing is poured first, and then a concrete wall (stem wall) is built up on the footing, with the slab itself laid down inside the perimeter formed by the stem wall. This method provides a raised platform for the slab.
T-Shaped Foundations
T-shaped foundations are primarily used in areas where the ground freezes. A footing is poured below the frost line, and then walls are constructed up to the ground level. The slab is then poured between these walls. This design allows the foundation to resist the forces exerted by frost heaving. The "T" shape comes from the footing and wall structure extending deep into the ground, providing extra stability against shifting soils.
Frost-Protected Shallow Foundations (FPSFs)
FPSFs are specifically designed to protect against frost heaving without needing to dig below the frost line. They use insulation panels placed around the edges of the slab to keep the ground temperature around the footings above freezing, thus avoiding frost heave. The footings in FPSFs are shallower than traditional footings but still crucial for structural integrity. They extend slightly into the ground and are insulated to prevent the transfer of freezing temperatures.
In all cases, the footings are essential for providing stability, distributing loads, and ensuring the longevity of the foundation against environmental and soil conditions. Each design adapts the basic concept of footings to meet specific climatic challenges and construction requirements.
Structural Requirements
The footings in slab foundations are crucial for distributing the load of the building to the ground and for providing stability. They help to prevent the slab from cracking or shifting by anchoring it against the forces exerted by soil expansion and contraction.
While slab foundations are simpler and often thinner than other types of foundations, they do include footings that are integrated into the design of the slab, providing necessary support and stability for the structure.
