A waffle slab is a type of reinforced concrete floor system characterized by a grid-like pattern of beams and slabs. This system is composed of thin, concrete slabs that have a series of ribs or beams cast into them in both directions, forming a waffle-like appearance. The ribs are typically spaced apart and add structural strength while also reducing the amount of concrete used, making the system more economical.
