The Florida limestone is a relatively soft rock which presents many challenges to engineers when designing deep foundations. One alternative is micropiles which have grown significantly from their early days as very small diameter, light capacity elements. Also known as minipiles, pin piles, needle piles or root piles, micropiles offer an attractive deep foundation alternative for sites with tight access, low headroom, and where difficult subsurface conditions or obstructions necessitate a small diameter, high capacity deep foundation. The ability to confirm the competence of the limestone bearing formation by drilling in a rock socket has made micropiles a growing deep foundation selection in Florida.
