CMU Blocks
Where Do I Start?
At Black Flag Contractors, we approach every CMU (Concrete Masonry Unit) block project with the utmost attention to detail and precision. Our process starts with a comprehensive site assessment to ensure the ground is properly leveled, graded, and prepared for a solid foundation. We then select high-quality CMU blocks and reinforce the structure with steel rebar to ensure strength and stability. Our team carefully arranges and lays each block to create a clean, even finish that aligns with your design goals. Whether building walls, retaining structures, or custom masonry, we use advanced techniques and adhere to all industry standards to guarantee durability and longevity.
We focus on clear communication throughout, keeping you informed every step of the way to ensure a successful and lasting result.

Deciding if a new block wall is the right fit for your space? A block wall will last for a long time; it's much more durable than a wood or vinyl fence.
Every block wall project we do has an option for rough face blocks that can add a lot of character and save money.
