Slab on Grade
A Slab on Grade is a common type of building foundation where concrete is poured directly on the ground, creating a flat base for buildings. It's different from traditional basement foundations because it sits right on the prepared soil instead of being elevated or having a space underneath. This method is popular in warmer climates and for commercial buildings, warehouses, and some residential homes. Construction professionals often work with these foundations because they're cost-effective and faster to build compared to other foundation types. You might also see this referred to as "ground-level foundation," "concrete slab foundation," or simply "concrete slab."
