As one of the world’s most durable, economical and functional building materials, Mutual Materials Concrete Masonry Units (CMU) come in a wide range of colors, shapes and textures. Consider blending CMU colors to meet your specific design needs. Mutual Materials can blend CMU colors at the plant saving you time and money.
Mutual Materials CMU conforms to the standards for load-bearing concrete masonry units as published by the National Concrete Masonry Association (NCMA) and meets or exceeds ASTM C-90 specifications.

Mutual Materials concrete masonry units meet ASTM C 90.
CONCRETE MASONRY WITH INTEGRAL WATER REPELLENT
All colored Mutual Materials manufactured concrete masonry units now come with RainBloc®, an integral water repellent. RainBloc, a liquid admixture manufactured into our block, resists wind-driven rain while still maintaining vapor transmission, reducing the chance of mold, mildew, and musty smells from developing inside a building.
Benefits of the RainBloc System:
- Resists rain water penetration
- Fights against mold and mildew
- Maintains masonry colors
- Resists efflorescence
RainBloc System features:
- Polymeric based
- Durable for the life of a masonry structure
- A full-wall thickness water penetration protection system
The RainBloc anti-wicking feature ensures that masonry units and mortar strongly resist water absorption. If rainwater seeps past the exterior face of the wall, the RainBloc system’s water repellent properties minimize the amount of water that can be absorbed into the concrete, causing any water inside the wall to flow to properly-installed wall flashing and weep holes.
For more information on the RainBloc system, please contact a Mutual Materials sales representative.
Color Disclaimer for CMU:
The Mutual Materials website shows options for both Ground Face and Split Face CMU, which provides the most consistency in color. While Mutual Materials can manufacture Smooth Face CMU, there can be variance in color due to the manufacturing process. Mutual Materials cannot guarantee color consistency from block to block and between different shapes for Smooth Face, colored CMU. Unpainted block can exhibit random color variations and Smooth Face CMU is best suited for painted applications.
