RESULTS FOR FOUNDATION

Definition: a system of structural elements that transmits loads from the structure above to the earth.- ACI Concrete Terminology

There are three foundation types: - T-shaped: A traditional foundation method to support a structure in an area where the ground freezes. A footing is placed below the frost line and then the walls are added on top. The footing is wider than the wall, providing extra support at the base of the foundation. - Slab-on-ground: A slab is a single layer of concrete, several inches thick. The slab is poured thicker at the edges to form an integral footing; reinforcing rods strengthen the thickened edge. The slab normally rests on a bed of crushed gravel to improve drainage. - Frost-protected: This foundation relies on the use of two sheets of rigid, polystyrene insulation—one on the outside of the foundation wall and the other laid flat on a bed of gravel at the base of the wall—to prevent freezing, which is a problem with slab-on-ground foundations in areas with frost.
