An unfolding disaster for Connecticut homeowners & towns



As many as 34,000 home foundations in Eastern Connecticut may be failing. A quarry in Willington, Connecticut was a longstanding source of aggregate used in concrete for building construction. The quarry contained a vein of the mineral pyrrhotite, which contaminated the aggregate, and so, the concrete used in foundations. In time, the mineral reacts with water and air, causing the concrete to crumble and foundations to fail.


The quarry’s products were used in an estimated 20,000 residential construction projects over 30 years. In some towns, dwellings comprising 30% of its taxbase were built during the years of most concern, 1983-2013. And recently, some municipal buildings were found to be affected, necessitating replacement.


Repairs proved ineffective. Replacement of the foundation is costly but the only currently effective solution. The process involves detaching accessory structures and utilities, lifting the house structure, demolishing the defective foundation and pouring a replacement foundation.


Homeowner claims were denied by insurers. FEMA declined assistance.


Homeowners formed grassroots organizations to advocate for assistance and provide information (see Coalition links below). The State of Connecticut Insurance Department warned insurers not to cancel insurance based on such a claim. US Representatives Joe Courtney and John B. Larson, with the support of US Senators Richard Blumenthal and Chris Murphy, obtained income tax relief for homeowners which now may span several years, and have sought HUD funding. The Capitol Region Council of Governments (CRCOG) assists towns and homeowners with pertinent information and its site is frequently updated.


The Connecticut legislature passed a bill which the Governor signed implementing the collection of a $12 surcharge on every homeowner insurance policy to fund a captive insurance entity to distribute funds for relief, almost entirely for crumbling concrete foundation owners (CFSIC). The surcharge should raise about $9 million. The state is authorized to borrow about $100 million. Remediation costs are likely to exceed $1 billion (source: CT Mirror, Mark Pazniokas, 5/5/2018 link below).


The Connecticut Foundation Solutions Indemnity Company (CFSIC) was created as a solution for handling documented homeowner claims. It is a captive insurer, in that it is not a conventional insurance company, but a special entity created to handle claims specific to the defective concrete issue in this state. This entity is funded by state bonds issued periodically. If the funds to the CFSIC are delayed or would cease, the CFSIC would have no capacity to pay out claims. That said, the CFSIC has no termination date. 


The scale of this disaster remains unknown. Please note that reports limiting the affected time period and source to by the Mottes quarry material may be inaccurate. The material is naturally present in some quarries and so it could be currently supplied for concrete pours. As far as I have been able to determine, there are no pertinent standards for oversight of this contaminant at the quarry level.


Since defective concrete predominantly affects residential properties, it is a residential appraisal issue. To provide information to appraisers, agents, and members of the public, I will add links to active groups and political representatives as well as news articles on this Renée Healion Appraisals website. The reader is cautioned that this is an unfolding issue and I am attempting to keep my links current. If there are any corrections or suggestions, please feel free to email me.
