Crumbling Foundations

Crumbling Foundations – Since 2017 Macchi Engineers has been providing services for crumbling foundations throughout Northern Connecticut. Thousands of homes and other building structures constructed mainly in the Northeastern section of Connecticut from 1983 may have concrete foundations that contain the iron sulfide mineral called pyrrhotite. This mineral was found in a quarry in West Willington Connecticut and was used in the production of concrete. Over time, concrete foundations containing pyrrhotite may be at the risk of cracking and crumbling and in severe cases require a full replacement. Our Firm provides services from the initial consultation to final design and construction administration and inspection. We have expertise providing foundation replacement and repairs including temporary lifting of residential structures. Services we provide include an initial consultation with property owners about the work required to make their property safe for occupancy. We assist with coordination for core sampling and petrographic analysis. Other relevant services include investigation and evaluation, reporting and cost estimates for repairs, shoring and structure stabilization, design of repairs, construction administration and inspection services.
Macchi Engineers has been contracted by the Town of Vernon to assist residential property owners with inspection and testing of their concrete foundations. We were also contracted by some Connecticut Banks to inspect the foundations of potential borrowers. Our firm has provided services to more than 1,000 properties with the potential of having a crumbling foundation due to the presence of pyrrhotite in their concrete foundation.
