Green Units

Cognizant of our responsibility to mitigate negative impact on the environment, Superior continues to innovate in the manufacture and design of eco-friendly concrete masonry units. In an effort to reduce carbon emissions we currently provide a 30% cement replacement and 20% reduced aggregate content, resulting in a block that is both structurally sound and environmentally responsible.
