CMUs (concrete masonry units) are concrete blocks that are molded into identical shapes made from cement, aggregates and water. Their identical shapes make them perfect for building block walls.
CMUs are designed to be the core of concrete block walls and/or concrete buildings that need to be built economically, efficiently, and for fire-resistance.
The CMU blocks are stacked in layers with mortar between each block. This makes the wall building process flexible and versatile.
