Washed and screened gravel ¹ is the best type to put beneath concrete slabs. Ideally, the gravel should measure ¾–1 inch in size. While larger gravel can still work well, compacting and leveling it can be quite troublesome. It could also be too porous for some types of concrete, meaning it'll require more of it.

A concrete slab's primary purpose is to provide a stable and load-bearing surface. Several critical factors influence the design: Soil Type and Load Capacity: The soil's load-bearing capacity is paramount. Different soil types have varying abilities to support heavy loads, and a thorough soil analysis by a professional engineer is essential.
