The underside of a waffle slab, showing the grid like structure. A waffle slab or two-way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside. [1] The name waffle comes from the grid pattern created by the reinforcing ribs.
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.
A waffle slab gives added strength in both directions using a matrix of recessed segments beneath the slab. [16] This is the same principle used in the ground-bearing version, the waffle slab foundation. Waffle slabs are usually deeper than ribbed slabs of equivalent strength, and are heavier hence require stronger foundations.
The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...
An open structure, the car park consists primarily of a grid of rectangular concrete columns with flared tops supporting waffle slabs which form the floors. Precast concrete panels with an exposed aggregate finish form the balustrades on the Turbot Street and Wickham Terrace elevations.
The overall mass of concrete can be reduced by 35–50% depending on the design, [1] as a consequence of reduced slab mass, as well as lower requirements for vertical structure and foundations. Biaxial slabs commonly span up to 20 metres at a thickness of around 500 mm. [ citation needed ] The added strength also reduces the acoustic ...

The stepped "concrete waffle" facing on the front of the dam was designed to accommodate this addition to the height. [6] This would have flooded land into Canada approximately 3 miles (4.8 km) further, also extending up the Klesilkwa River , a Skagit River tributary, and provided the opportunity to generate about 272 MW of extra power ...
