Concrete Block Buildings Provide Exceptional Safety for Returning Students This Academic Year
As a new academic year unfolds, many communities across the nation are invigorated by the promise of fresh beginnings. However, beneath this excitement lurks a pressing reality: not all school buildings are equipped to protect their occupants in today’s challenging environment. Every day, countless students and educators step into facilities that fall short in withstanding potential threats such as fires, severe weather, or security breaches. While discussions around school safety often center on policies and emergency protocols, the structural integrity and resilience of the buildings themselves are frequently overlooked.
In this regard, concrete masonry units (CMUs) stand out as a particularly robust solution. These buildings boast inherent fire resistance, durability against impacts, and resilience to storms, affording continuous protection without the necessity for costly renovations or upgrades.
So why isn't concrete masonry the prevalent choice for school construction? A recent report by the Southeast Concrete Masonry Association sheds light on the compelling benefits of CMU in educational settings:
1. Fire Containment: CMU walls effectively confine fires 93% of the time, able to endure flames for up to four hours. This critical feature provides essential time for students and staff to evacuate safely in case of an emergency.
2. Storm Resilience: CMU can withstand winds and debris from severe weather events reaching up to 250 mph, ensuring safety during natural disasters.
3. Sound Transmission Control: CMU construction minimizes noise interference by blocking sound from room to room and absorbing cacophonous noise within bustling spaces like classrooms, cafeterias, and gymnasiums.
Beyond their ability to combat extreme weather, schools built with CMUs are designed to endure everyday wear and tear. The sturdy nature of concrete block construction can handle the bustling activity of crowded corridors, lively lunch periods, and energetic gym classes without compromising structural integrity or aesthetics over time.
Real-World Applications of Safe Construction
The effectiveness of CMU school buildings is evident in numerous real-life examples where districts have opted for enhanced safety during the rebuilding process after catastrophic events. For instance, in Florence, Alabama, a new middle school was opened in 2019, spanning 180,000 square feet. It employs CMU in its construction and includes a gymnasium that serves as a FEMA-rated storm shelter, large enough to protect three times the school's student capacity.
Similarly, after severe tornadoes devastated schools in Joplin, Missouri in 2011 and Moore, Oklahoma in 2013, both districts rebuilt their facilities with FEMA-rated safe rooms constructed from reinforced concrete masonry. Notably, Moore incorporated CMU-walled classrooms that can withstand winds of up to 250 mph, while Joplin deployed hardened facilities across the district to safeguard students and staff in anticipation of future storms.
James Cain, President of the Southeast Concrete Masonry Association, emphasizes the critical role schools play in communities, stating, "Schools are the heartbeat of our communities. They deserve to be built strong enough to protect everyone who walks through their doors."
Long-term Value Beyond Safety
Concrete masonry offers school districts significant advantages beyond immediate life-safety benefits. These include:
With public educational construction expenditures surpassing $111 billion as of mid-2025, now is the opportune moment to reassess and redefine what modern school safety entails. Utilizing the Block Design Collective (BDC), an initiative by the Concrete Masonry Checkoff, architects, engineers, and builders can access free technical design assistance aimed at creating smarter and safer learning environments using CMUs.
Kim Spahn, CEO of Concrete Masonry Checkoff, expresses optimism for future designs, stating, "The next generation of designers can benefit greatly from the Block Design Collective. We're here to help them unlock the full performance potential of concrete masonry, particularly where safety, durability, and long-term value are vital."

Long-term Value Beyond Safety
Concrete masonry offers school districts significant advantages beyond immediate life-safety benefits. These include:
- - Lower Insurance Premiums: Buildings made of CMU generally receive lower insurance rates when compared to wooden-framed structures.
- - Energy Efficiency: The high thermal mass of concrete blocks helps to regulate indoor temperatures, significantly reducing HVAC demands and promoting energy savings.
- - Minimal Maintenance Costs: CMU is resistant to wear, weather conditions, and pests, translating to reduced repair costs over extended periods.
