Continuous Flight Auger pile
A Continuous Flight Auger (CFA) pile is a type of deep foundation used in construction. It involves drilling a hollow auger into the ground while simultaneously injecting concrete through the auger as it is withdrawn. This method creates a strong, stable pile that can support heavy structures.
CFA piles are particularly useful in areas with limited access or where vibrations must be minimized. They are often used in urban settings and can be installed quickly, making them a popular choice for projects involving bridges, buildings, and retaining walls.
