What is a pile used for in construction?

A pile is primarily used in construction for transferring loads to stronger soil. This method is particularly important when the surface soil is too weak to support the weight of the structures above. Piles are long, slender columns typically made of concrete, steel, or wood that are driven deep into the ground to reach more stable soil or rock layers. By utilizing this technique, engineers can ensure that the load of the structure is effectively conveyed down to foundations that can bear it, thus preventing settlement or failure.

This function is crucial for projects that involve heavy structures or are built in areas with poor soil conditions. The design and choice of pile type depend on various factors, including soil characteristics, load requirements, and environmental conditions, all of which are pivotal in ensuring the stability and safety of a construction project.
