The mineral is known to naturally react over years with water and oxygen, causing devastating damage to concrete basements and foundations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt would be a very positive development,\u201d said U.S. Rep. Joe Courtney, acknowledging the technology could be years away. The Democrat\u2019s district includes many of the 36 Connecticut communities identified as potentially having the crumbling basement problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A Vernon resident, Courtney said some of his affected neighbors have tested for pyrrhotite, an expensive process involving multiple borings into concrete walls. The ultimate fix involves replacing an entire foundation or basement could have a price tag up to $200,000.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Courtney said the Navy\u2019s efforts have been totally independent of any requests made by the state\u2019s congressional delegation or Democratic Gov. Dannel P. Malloy, who have been working to persuade the Federal Emergency Management Agency to provide financial assistance to the homeowners for what they contend is a slow-moving natural disaster.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAs a large consumer of concrete, with a big footprint of military installations in the U.S., they actually decided they wanted to find a way to make sure their structures are sound,\u201d said Courtney. Currently, no Navy structures have been identified as having problems associated with pyrrhotite.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Naval Facilities Engineering Command in Washington recently chose three companies to begin developing a portable device or test kit that can analyze pyrrhotite in damaged concrete structures, as well as loose aggregate before it is mixed into fresh concrete.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The firms have received federal funding to test their hypotheses that their proposed technologies can detect pyrrhotite in a controlled environment, a process that should take six months, said Theresa Hoffard, research chemist at the Command.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Prototypes are expected to be developed by the end of the second phase of the process, which usually takes two years. If a company makes it that far, the third and final phase involves commercialization of the product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe are hopeful that a viable device will be produced, but cannot predict with certainty,\u201d Hoffard said. He added how the Navy wants to prevent future Navy concrete construction from inadvertently using pyrrhotite.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1700\" height=\"1133\" src=\"\/wp-content\/uploads\/2026\/08\/AP17201607554077.jpg.jpg\" alt=\"\" class=\"wp-image-64303\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP17201607554077.jpg.jpg 1700w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP17201607554077.jpg.jpg?resize=300,200 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP17201607554077.jpg.jpg?resize=768,512 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP17201607554077.jpg.jpg?resize=1024,682 1024w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP17201607554077.jpg.jpg?resize=1536,1024 1536w\" sizes=\"auto, (max-width: 1700px) 100vw, 1700px\" \/><figcaption class=\"wp-element-caption\">In this April 11, 2017, file photo, Tim Heim, a founder of the Connecticut Coalition Against Crumbling Basements, points out damage in his basement foundation due potentially to the presence of the mineral pyrrhotite in the concrete in Willington, Conn. (Susan Haigh\/AP)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The Navy has cited recent reports of pyrrhotite-caused structural damage in the U.S., Canada and Europe, \u201cindicating the problem may be much more widespread than previously thought.\u201d Hoffard said the Navy hopes Connecticut can ultimately use the device, if it\u2019s successful.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Connecticut Sen. Richard Blumenthal, a Democrat, is hoping it could help in the state\u2019s efforts to get a handle on the scope of the problem. Malloy has said the state needs a better idea of exactly how many homes in Connecticut are affected in order to make a stronger case for financial assistance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAn easier, virtually costless device will enable us to make the case more compelling and clear because it will show the vast magnitude of the problem,\u201d he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As of July 14, the Connecticut Department of Consumer Protection had received complaints from 545 homeowners with crumbling foundations. But that number is expected to grow much higher once any financial assistance becomes available, an issue that\u2019s also being pursued by the General Assembly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s been estimated that thousands of homes are affected by the problem, which could ultimately cost more than $1 billion to repair.<\/p>\n\n\n\n<p
