Building Storm-Ready Homes: Your Guide to Sourcing Quality Masonry Materials for Hurricane-Resistant Construction in Nassau County
When severe weather threatens Nassau County, New York, the difference between a home that stands strong and one that suffers catastrophic damage often comes down to the quality of construction materials and techniques used. After Hurricane Andrew in 1992 caused $16 billion in insured damage, the state of Florida established new building standards and enforcement. The state increased performance criteria for wind-load provisions and adopted new wind provisions from the American Society of Civil Engineers. While Nassau County isn’t Florida, these lessons in hurricane-resistant construction are invaluable for coastal communities everywhere.
The Foundation of Hurricane Resistance: Quality Masonry Materials
The key to hurricane-resistant construction lies in selecting the right masonry materials and understanding how they work together to create a resilient structure. One of the strongest building materials available, concrete is incredible at withstanding pressure and stress. Concrete is dimensionally stable, and does not contract or expand during extreme weather events. While concrete is naturally strong under compression, adding steel reinforcement makes concrete a force to reckon with.
Concrete block walls, built right, offer one of the best wind resistances available for residential construction. Filling cavities in the blocks with high-strength grout or concrete mix, using the recommended psi of filler, and employing Type S mortar for strong connections are all vital aspects of reinforcing the wall. The science behind this effectiveness is clear: steel-reinforced concrete wall assembly acts as a monolithic composite system with superior resistance to hurricane-induced forces. When a point impact load or a sustained lateral load is imposed against the wall surface, the composite system acts to spread the forces through the system, thereby reducing the “stress” — and the potential for failure. The concrete (strong in compression, but not in tension) and the steel mesh (strong in tension, but not in compression) work in tandem, creating a wall assembly that is strong in both tension and compression.
Essential Materials for Hurricane-Resistant Masonry Construction
When sourcing materials for hurricane-resistant construction in Nassau County, contractors and homeowners should prioritize several key components:
- Reinforced Concrete Blocks (CMU): For hurricane resistance, specific techniques are employed: Vertical Rebar and Grout: Hollow block cores are filled with concrete grout and reinforced with vertical steel rebar, creating a solid, reinforced concrete column within the wall.
- High-Strength Grout: To achieve optimal results, use a filler with a compressive strength of at least 3,000 pounds per square inch (psi). This high-strength filler enhances the overall structural integrity of the concrete wall, and, when used with rebar reinforcement, gives the wall a much higher resistance to tension.
- Type S Mortar: For reinforcing walls against wind forces, a Type S mortar is often recommended. Type S mortar contains a higher proportion of cement compared to other mortar types, providing increased bond strength and durability.
- Steel Reinforcement: Reinforcing bars, known as rebar, play a crucial role in increasing the tension strength of concrete walls. For an 8 ft. tall, 12 ft. wide wall, for instance, a minimum of two horizontal rows of rebar should be used. The rebar should have a minimum diameter of ½ inch.
Why Professional Guidance Matters
Sourcing quality materials is only part of the equation. Understanding how to properly implement these materials requires expertise and experience. Un-reinforced masonry has not fared well in strong hurricanes. Most of the collapsed buildings in Hurricane Charley were un-reinforced masonry buildings. If the walls are tall or if the roof structure that is providing lateral support for the tops of the walls is damaged, un-reinforced masonry walls will collapse
This is where working with knowledgeable suppliers becomes crucial. Professional guidance ensures that you’re not just buying materials, but sourcing the right materials for your specific project requirements and local building codes.

Planning Your Hurricane-Resistant Project
When planning a hurricane-resistant masonry project in Nassau County, consider these critical factors:
Material Quality: Filling cavities in concrete blocks has a big impact on the overall strength and stability of the wall. The cavities are typically filled with a high-strength grout or concrete mix, often including “pea gravel.” This filling process ensures that the blocks act as a solid unit, reducing the risk of failure under intense wind forces.
Professional Installation: It’s also key to connect the whole wall via steel to the concrete footers. This connection is crucial for overall structural integrity during severe weather events.
Code Compliance: For fortress-like strength, follow local building codes in high risk areas, installing impact-resistant windows and doors and secure roofing systems.
The Investment in Safety and Peace of Mind
While hurricane-resistant construction may require a higher initial investment, the long-term benefits are substantial. A reinforced concrete block home envelope, when all the rebar, mortar and labor are added up, will probably cost about as much as a wood-framed home. But it will be a little more wind resistant, and a lot easier to clean up if the property is inundated with flooding but survives the ordeal.
Modern reinforced masonry wall houses have been found to perform quite well in hurricanes. This performance translates to reduced insurance costs, lower repair expenses, and most importantly, enhanced safety for your family.
When severe weather threatens Nassau County, having the right materials and construction techniques can mean the difference between minor repairs and total reconstruction. By partnering with experienced suppliers like Valley Supply and focusing on proven hurricane-resistant masonry techniques, property owners can build with confidence, knowing their structures are prepared to weather whatever storms may come.
