A "Slab On Grade" is a type of foundation commonly used in construction. It consists of a thick, flat concrete slab poured directly on the ground, providing a stable base for buildings. This method is often chosen for its cost-effectiveness and simplicity, making it suitable for various structures, including residential homes and commercial buildings. This foundation type is particularly effective in areas with stable soil conditions. It helps prevent moisture issues and is less prone to settling compared to other foundation types. However, proper site preparation and drainage are essential to ensure its longevity and performance.
