Level on ground structure. Explanation:Slab-on-grade Slab is the concrete (or other material) platform placed as base for construction. On-grade means right on the ground. So slab-on-ground means that the building has a concrete (or other material) slab or platform placed right on ground soil.
In some cases, the concrete is placed directly on the subgrade, but it is strongly recommended that a granular sub-base be placed between the native soil and the concrete slab. A concrete sidewalk is typically a 100 to 150 mm thick slab on grade. Usually, the distance between construction joints (slab length) is marginally larger than the width of the sidewalk.
