Pile Foundation
A pile foundation is a type of deep foundation that buildings and structures use when the ground near the surface isn't strong enough to support them. Think of it like very long, strong columns that are driven deep into the ground until they reach solid rock or strong soil. It's similar to how a table with long legs provides better support than one with short legs on soft ground. Engineers use pile foundations for large buildings, bridges, and structures in areas where the soil is weak or there's water nearby. This is a fundamental concept in construction and civil engineering that appears frequently in job descriptions for structural engineers and foundation specialists.
