A concrete pile is a long, cylindrical structure made of reinforced concrete, used to support buildings and other structures. These piles are driven deep into the ground to reach stable soil or bedrock, providing a strong foundation. They help distribute the weight of the structure evenly and prevent settling or shifting over time. Concrete piles come in various types, including precast and cast-in-place. Precast piles are manufactured off-site and transported to the construction location, while cast-in-place piles are formed directly in the ground. Both types are essential in construction, especially in areas with weak or unstable soil.
