Micropiles, also commonly referred to as pin piles, needle piles, mini piles are constructed as 3-10” diameter friction or end bearing piles. These piles when used in the appropriate application are able to carry loads of over 170 tons although their regular uses rarely exceed 50 tons in Southwest Florida. At Coastal Foundation Solutions, we commonly use micropiles in areas with limited access, to underpin existing structures, or to aid in foundation expansion applications.
