MONOLITHIC SLAB FOUNDATION

Monolithic slab foundations are the simplest, fastest, and cheapest types of foundations available. The fact that they are poured in one go means that they are efficient to make, and they also provide a solid foundation. The absence of seams and cold joints (plus the addition of some steel reinforcements) gives monolithic slab foundations a rigidity and stability that makes them extremely strong.

In some cases, you can pour a monolithic slab foundation yourself, meaning they are a great option for smaller structures such as sheds or mother-in-law construction (although if in doubt, hire a professional).
