Foundation PierA pier is a drilled shaft varying in diameter and depth. Depending on the size of the structure,
there could be as many as 100 drilled piers or
as few as one. After the pier hole is drilled, it is

certain structures, houses and buildings to help
minimize structural damage done by ground
shifting or ground settling. Pier drilling can also
be used for bridges and overpasses, fence
posts, boat ramps and sign posts.
