PRODUCT > SLUMPSTONE™ CMU
Split Face CMU
Split Face CMU provide a textured architectural masonry surface created by mechanically splitting the block face to expose the aggregate matrix. The result is a roughhewn stone appearance that creates depth, shadow, and visual interest across masonry walls.
Distinctive Surface Finish
Angelus Split Face units are manufactured for consistent coursing and alignment while maintaining the natural variation expected from split masonry textures.
Regional Production
California manufacturing for faster lead times and lower transport impact.

The workhorse of architectural masonry. Available in the 4″, 6″, 8″, 12″ widths with a range of unit configurations to handle any coursing condition, corner detail, or structural requirement.
- 4, 6, 8, 10, 12-inch wide. Ring and double open end available in 16-inch.
- Consistent face dimensions for clean joint alignment
- Compatible with standard masonry detailing and reinforcement
- Suitable for CMU veneer, structural walls, and interior partitions
Design Note: Wide unit configurations are subject to plant availability. Contact your Angelus rep to confirm sizing and lead times before issuing for bid.
Scores and Flutes
Score and Fluted blocks are designed to transform traditional masonry walls into expressive architectural surfaces. Through scored joints and fluted projections, these units introduce structured patterns that enhance light, shadow, and façade composition.
- Score units are typically special order with configuration options and plant-dependent availability.
Manufactured by Angelus Block in compliance with ASTM C90 for loadbearing concrete masonry units.
- Wall assemblies may achieve fire ratings up to four hours depending on thickness and grouting.
Included in EPD and HPD documentation and contain no VOCs, supporting sustainable building programs.
Design Note: Score Precision CMU are typically produced as special-order units and may require additional lead time for manufacturing, color selection, and plant availability; confirm availability early in the design or bidding phase.
Projected Shadow Dimensional Masonry
Projected Shadow introduce shadow lines and surface variation to masonry walls while retaining the durability and performance of standard concrete masonry construction. Multiple profiles allow designers to create patterned or accent masonry installations.
Dimensional projections create shadow lines and surface variation across masonry walls.
- Primarily manufactured as special-order units with optional configurations and integral color selections.
- Manufactured in accordance with ASTM C90 Standard Specification for Loadbearing CMUs.
Depending on wall construction, assemblies may achieve fire ratings of up to 4 hours.
- Products are included in Type III EPD and HPD and contain no VOCs.
Design Note: Because many Projected Shadow units are produced to order and may vary by plant, confirm availability and scheduling with your Angelus rep during design development.
