Pile Foundations
Pile foundations are deep foundation systems used to support structures by transferring loads to deeper, more stable soil layers. They consist of long, slender columns made from materials like concrete or steel, driven or drilled into the ground. This method is particularly useful in areas with weak or unstable surface soils.
There are two main types of pile foundations: end-bearing piles, which transfer loads directly to the bedrock or strong soil, and friction piles, which rely on friction between the pile surface and surrounding soil. Pile foundations are commonly used for buildings, bridges, and other heavy structures where traditional shallow foundations are inadequate.
