In situations where access is limited and site conditions are unsuitable for pipe piles or helical piers, hand excavated piers are an option of stabilizing foundations. The piers are excavated by hand using pneumatic tools and electric hand-held tools, a rebar cage is built inside the excavation, and the pier is backfilled with concrete. The piers are connected to the foundation with a concrete cap and epoxy-set rebar. Structures can be releveled with hand excavated piers by lifting the foundation before connecting the pier to the foundation.
