While concrete and clay masonry units are the most common, there are other types available for specialized uses. These include cast stone and calcium silicate. Once manufactured, CMUs are suitable for many architectural, construction and landscape applications. A CMU wall is a common application for concrete blocks, secured with mortar for added strength and durability.
When properly manufactured and maintained, they can last up to 100 years, as the materials resist deterioration over time, meaning that building with CMU helps ensure the longevity and integrity of the structure.
