A ribbed reinforced concrete slab-on-ground foundation has a lower cost compared to a constant-thickness slab foundation while providing the same strength and stiffness. Additionally, it can be constructed more quickly due to the use of less concrete and can also avoid the need for control joints. The formwork for both types of slab foundations is typically similar.
