A pad foundation is a type of shallow foundation used to support individual columns or structural loads. It consists of a thick, flat concrete slab that distributes the weight of the building or structure evenly over the soil. This helps prevent excessive settlement and ensures stability. Pad foundations are typically used in areas with good soil conditions, where the load-bearing capacity is sufficient. They are often employed in residential and light commercial buildings, making them a popular choice for construction projects. Proper design and placement are crucial to ensure the foundation's effectiveness and longevity.
