Please join APT WGLC for a members-only webinar presented by James LaBelle, P.E., Doc.E.
In Milwaukee and other cities, some historic buildings were founded on untreated wood piles. Changes over time in the ground water level sometimes causes portions of the piles to become unsubmerged. If this condition persists long enough, rotting will result. As rotting progresses, the reduction of support in masonry buildings will then often cause distress (sometimes severe) such as cracked walls, out-of-level floors and door operation problems. Severely rotted piles lose their load-resisting ability and cause nearby sound or less-rotted piles to resist more load, thus reducing the safety factor of the foundation system. Examples, including photos, of investigation and repair of several buildings (1870s to 1890s) are presented. References are listed.
