What is rotary pile?

A rotary pile is a type of deep foundation used to support structures by transferring loads to deeper, more stable soil or rock layers. It is constructed by drilling a hole into the ground and then filling it with concrete or other materials, often reinforced with steel. The rotary method involves using a rotating drill bit to create the hole, allowing for precise control and effective excavation in various soil conditions. This technique is commonly employed in construction projects requiring strong foundational support, such as high-rise buildings and bridges.
