About CO2nvert Technology

"Green” your grey block or Architectural CMU with CO2nvert. Oldcastle has partnered with CarbonCure™ to permanently sequester CO2 inside our concrete masonry units, without compromising quality, color and texture. The process is called CO2nvert and the result is an improved ecofriendly, green CMU with a reduced carbon footprint that can help attain credits for LEED v4. Now CO2 from smokestacks can be permanently captured and converted inside Oldcastle concrete masonry products.


CO2nvert is a performance upgrade option, which means it can be paired with other masonry units from Echelon​

Greener Concrete Means Better Concrete

Being green doesn't have to mean compromising on quality or price. Carbonation does not affect the color, texture or durability. The result is the same Oldcastle Architectural concrete product you trust--now with a reduced carbon footprint. Apply CO2nvert with captured CO2 to select Oldcastle concrete masonry products.
