CarbonBuilt improves product quality while lowering the plant’s carbon footprint by up to 70% by replacing up to 50% of cement with Reversa, decreasing waste, and implementing targeted operational enhancements.
CarbonBuilt, a profoundly decarbonized concrete maker, said that it is currently producing low carbon concrete masonry products at its first fully-owned manufacturing plant in Danielson, Connecticut, using its Reversa binder technology. EC3 evaluated the company’s normal weight concrete masonry as having the lowest carbon footprint in the United States.
The former Jolley Concrete plant, acquired in February, has been rebranded as “CarbonBuilt,” marking the end of the 70-year-old family-run business. “This is a defining moment for CarbonBuilt,” said CEO Michelle Carvin. “With the conversion of the Danielson plant complete, we’re demonstrating how our innovative Reversa technology combined with more efficient operating processes is transforming the future of concret.” We are now making high-performance items with significantly lower carbon emissions. Building owners, architects, general contractors, and masons in the Northeast can now acquire concrete masonry pieces with great quality and a significant environmental impact without paying a premium.
Reversa, made from a special blend of repurposed industrial materials, replaces standard carbon-intensive cement in concrete manufacturing, resulting in a significantly lower carbon footprint.

CarbonBuilt’s investments since acquiring the Danielson factory have increased operational efficiency, enhanced product quality, and reduced cement use and waste. The factory has an annual manufacturing capacity of approximately 80,000 tons of concrete, with ambitions to offer low-carbon segmental retaining walls and architectural masonry products in the near future.
