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.
