About Precast Concrete Piles - the Pros and Cons

The most common type of them, a precast concrete pile is a deep foundation used to transfer loads from a upper, soft layer of soil to a hardar, capable lower layer. They can be rectangular, square, round or polygonal in shape. Extra reinforcements are provided in the concrete so as to provide support for the forces received before the instalent.
The precast concrete piles are constructed in a casting yard. Then they are transported to the required location and installed as necessary. They are constructed by pouring the concrete in a conventional reinforcement cage. This has several steel bars in horizontal and vertical positions, held together by individual or spiral ties.
Types of Precast Concrete Piles - There are two main categories into which we can divide:
1. Driven Precast Concrete Piles: It is precast in a construction yard and then hammered into the soft ground at the target location. At most they can go up to 40 feet deep.
2. Bored Precast Concrete Piles: After they are made in the construction yard, they are transferred to the target location. The location already has boreholes for the piles; they are just lowered into these holes. Any space remaining between the bore hole and the pile is grouted.
