Originally the problem was though to be limited to 40 mile radius of the JJ Mottes Concrete Company, of Stafford Springs, which has been identified as the source of the concrete using rock aggregate containing pyrrhotite.
More recently the problem has been found in Rutland and Holden.
Crumbling foundations were caused by concrete containing the mineral pyrrhotite, which expands when exposed to water and oxygen, causing the concrete to swell and crack. The
Concrete poured between 1982 and 2015, from JJ Mottes Concrete Company, of Stafford Springs, which are within 40 miles for the concrete plant are potentially impacted by this concrete, the Special Commission has determined those within 20 miles of the plant are the most at-risk.

Building Officials can not through records determine if your house has the failing concrete and can only offer a courtesy inspection of your foundation. The only conclusive way to determine if any concrete contains pyrrhotite is to have it tested.
The Massachusetts Federation of Building Officials neither endorses or recommends any contractors, testing laboratories or registered professionals for the investigating, testing, or repair of any foundation or other associated work on new or existing homes.
