For architects, builders and specifiers, finding the right materials is critical to a project’s success. Architectural blocks are one of the most versatile and reliable building products available, offering limitless design possibilities. 

Nitterhouse Masonry Products is your headquarters for a comprehensive collection of architectural block shapes, with the key details you need to choose the right option for your design and specifications. We manufacture our durable architectural blocks to meet the applicable standards for their use, with load-bearing architectural CMUs complying with ASTM C90 and non-load-bearing units complying with ASTM C129.

A Complete Guide to Our Architectural Block Finishes

The finish of your architectural concrete block defines the building’s texture and character. We offer several distinct styles to match your vision:

  • Polished: This finish creates a glossy, smooth surface that gives projects a modern and sophisticated look resembling polished stone.  
  • Ground face: Grinding the block face reveals the natural aggregates within, resulting in a smooth, uniform and richly textured appearance often favored for schools and public buildings.
  • Split face: Splitting the block during the manufacturing process creates a rough, stone-like texture.
  • Antique (shot-blast): This finishing process exposes the natural beauty of the aggregates, providing a weathered, rustic look ideal for projects aiming for a timeless or classic feel.

Architectural Block Types and Sizes

Beyond the finish, the block’s physical shape serves specific structural and design functions. We offer a wide variety of architectural block shapes to suit any application:

  • Stretcher: Provides the foundation of most standard wall construction.
  • Bullnose: Creates soft, rounded corners and edges for a finished look.
  • Lintel and beam: Accommodates horizontal reinforcement (rebar) within a wall structure.
  • Corner: Ensures clean, strong corners without requiring extensive on-site labor and cutting.
  • Scored and fluted: Features pre-cast vertical lines that add texture and create unique shadow effects for decorative flair.
  • Monarch: Delivers the classic, desirable look of brick with the structural efficiency of a concrete masonry unit.

How to Choose the Right Architectural Block

The first step in selecting a block is to consider application factors, such as the need for load-bearing units, whether it is for interior or exterior use and what environmental conditions it must endure. 

Next, match the style to your design aesthetic. Consider how different finishes, textures and block shapes will contribute to the building’s overall appearance and architectural character.

Finally, review technical data sheets and industry resources from the Concrete Masonry & Hardscapes Association (CMHA) to ensure your selected block meets the necessary project specifications.
