Slab On Ground Floor

Subgrade the soil against which the ground bearing slab construction is placed but not cast.
Slab on ground floor. Slabs transmit the applied floor or roof loads to their supports. Ground bearing slabs also known as on ground or slab on grade are commonly used for ground floors on domestic and some commercial applications. A ventilated slab on ground floor structure constructed with finnfoam will also work in larger buildings where the ground temperature is higher in the center of the building. Concrete slabs that form the ground floor of a building may be either supported on beams called a suspended slab or supported directly on the subsoil via hardcore for example called a ground bearing slab.
The higher the a p value the greater the thermal resistance. Slabs may be classified into two main groups depending on whether they are supported on the ground or suspended in a building. Figures 1 7 show the results of thermal modelling a simple 10 m by 10 m square floor slab with an area a to perimeter length p of 100 40 2 5. Because the ground under a slab provides insulation the primary heat flow path is through the perimeter of the slab.
In addition the surface material of the slab may be highly vapor proof. A typical components of ground bearing floor slab. Subbase a graded material usually made from broken masonry and or rocks. Types of floor slab.
Ground slabs are those slabs that are poured directly into excavated trenches in the ground. They rely entirely on the existing ground for support. The structure will also reduce the radon risk.
