Bottom driven piles are a commonly used form of building foundation that provides support for structures, transferring loads to different layers of soil and rock that have the sufficient weight bearing capacities and suitable settlements.
Driven piles are commonly used to support buildings, walls or bridges, and can be the most cost-effective deep foundation solution. They can also be used in embankments, retaining walls and anchorage structures.
A foundation is described as piled when its depth is more than three times its breadth. A driven pile is a long, slender column made of preformed material and having a predetermined shapes and sizes that can be installed by impact hammering, vibrating or pushing it into the ground to a design depth or resistance. If the ground is particularly dense, pre-drilling may be required to allow the pile to reach the required depth.
