Pad foundations are a type of shallow foundation used to support individual columns or loads in a building. They consist of a concrete slab or pad that distributes the weight of the structure over a larger area of soil, helping to prevent excessive settlement. Pad foundations are typically used in situations where the soil has sufficient bearing capacity. These foundations are often square or rectangular in shape and can vary in size depending on the load they need to support. They are commonly used in conjunction with other foundation types, such as strip foundations or raft foundations, to provide stability and strength to a structure.
