Slab-on-grade or floating slab foundations are a structural engineering practice whereby the concrete slab that is to serve as the foundation for the structure is formed from a mold set into the ground. The concrete is then placed into the mold, leaving no space between the ground and the structure.
Another common type of shallow foundation is the slab-on-grade foundation where the weight of the structure is transferred to the soil through a concrete slab placed at the surface. Slab-on-grade foundations can be reinforced mat slabs, which range from 25 cm to several meters thick, depending on the size of the building, or post-tensioned ...
Waffle slab foundations adhere to International Building Code requirements. By 2008, most states put into effect the changes adopted in the 2006 IBC and, in regards to foundations, the on-grade mat foundation has become a more attractive design because, as an engineered system, it already accommodates the 2008 design recommendations, and required no major modifications to bring it into compliance.
For a suspended slab, there are a number of designs to improve the strength-to-weight ratio. In all cases the top surface remains flat, and the underside is modulated: A corrugated slab is designed when the concrete is poured into a corrugated steel tray, more commonly called decking. This steel tray improves strength of the slab, and prevents ...

In the United Kingdom most subsidence claims are for buildings at least 40 years old with shallow strip foundations. This is one of the most common types of foundations suffering from subsidence-related damage and according to the Building Research Establishment subsidence database, mass concrete underpinning was the most common underpinning ...

It is a component of a shallow foundation. [1] Wall Footing. Wall footings carrying direct vertical loads might be designed either in plain concrete or in reinforced concrete. Since a wall footing deflects essentially in one way, it is analyzed by considering as a strip of unit width and its length.
