Shallow foundation refers to a type of foundation that is placed relatively close to the ground surface, typically at a depth less than the width of the foundation. This type of foundation is used when the soil near the surface has sufficient strength to support the load of the structure without excessive settlement. Shallow foundations are commonly used for smaller buildings, residential houses, and light structures, where the load-bearing capacity of the surface soil is adequate. They typically include spread footings, strip footings, mat foundations, and slab foundations. Shallow foundations are simpler and more cost-effective compared to deep foundations because they require less excavation and material. The design of a shallow foundation depends on factors such as soil type, load distribution, and the weight of the structure. Shallow foundations are effective in areas with strong, stable soils, but they may not be suitable for locations with soft or weak soil layers. Proper site evaluation, including soil testing, is essential to determine if a shallow foundation can provide the necessary stability. This type of foundation is particularly beneficial in areas where high groundwater levels or deep unstable layers are not a concern.
