Types of Foundations and Their Uses

Shallow foundations, such as individual footings, combined footings, strip footings, and raft foundations, are used in soils with good bearing capacity. Deep foundations, like pile foundations and drilled shafts, are used in soils with poor bearing capacity. Factors like water table depth, underground obstructions, seismic activity, and cost should be considered when choosing a foundation. Consulting a structural engineer is crucial for selecting the appropriate foundation for a project.
