Piles are vertical structural elements, typically used to transfer the surcharge loads to deeper, more competent soil strata. Piles are classified based on their installation method into bored piles or driven piles. Additionally, their load transferring mechanism categorize them as end-bearing piles, frictional piles or combination of both.
In bored piles (also known as replacement piles, cast in-place piles or caissons), soil is drilled out during piles installation and reinforcement cage is lowered into the open hole which is later filled with concrete. In order to keep the hole open and ensure the hole is stable during installation procedure, temporary casing or bentonite mud may be utilized as needed.
In contrast, driven piles are prefabricated piles, constructed from steel beams or reinforced concrete that are installed in the ground through either vibratory or impact methods.
Both bored and driven piles are developed based on factors like soil type, environmental consideration and project requirements, ensuring the right fit for each project.
