Concrete Masonry Units (CMU) or Concrete Block are known for their strength and durability. However, today they are more than just building blocks. Texture and color combinations are endless with the products that are available on the market. Block also contributes to sustainable design through its long life span, energy efficiency, durability, local availability, acoustic insulation, low construction waste, and potential for reuse.
