Quick Summary

A friction pile is a type of foundation used in construction when the soil is too soft to support a building's load, even with bearing piles. Unlike bearing piles, which transfer loads to a stronger soil layer deeper underground, friction piles rely on the surface friction between the pile and the surrounding soil to support the structure's weight. These piles, often made of wood or concrete, are driven into soft soil where no suitable bearing stratum exists beneath the site. Piles in general are postlike foundation members used to support structures, especially on unstable soils or when dealing with exceptionally large loads. They are installed using pile drivers, which are machines designed to drive piles into the ground.12
