Why Concrete Masonry

MUCH MORE THAN BLOCKS….

CMU buildings and homes serve as much more than mere structures composed of blocks. While they provide protection from the elements and a safe place for rest, their significance extends far beyond these basic functions. These buildings and homes are where we gather with family and loved ones, build our careers, and celebrate major life events such as birthdays and graduations. They are the venues where we support our teams and celebrate their victories, witness the magic of Santa Claus, and welcome the New Year. CMU serves as the backdrop for many cherished memories and plays an integral role in defining the places we call home. This is CMU.

The Benefits of Using Concrete Masonry Units

Choosing construction materials can take time, as it is important to ensure the best possible end product. CMUs are one of several materials that can be used, depending on the scope of the project and several other factors. The advantages of CMUs in construction include:

American Made & Locally Sourced

CMU are made in the USA. CMU are made locally and are transported up to 100 miles to the job site.

Resilient Design to Sustainability

Manufacturing building materials often results in waste. However, concrete blocks are produced for each project, resulting in minimal waste. Moreover, their energy-efficient properties reduce heating and cooling costs, which is better for the environment. Concrete used in masonry applications like manufacturing CMUs can be crushed and reused as raw materials, making them recyclable. CMUs offer a sustainable and eco-friendly option from the manufacturing phase through their entire life cycle.

Acoustics

Walls and other structures made from CMUs create an effective sound barrier, blocking out unwanted noise and creating a quieter environment .This feature is particularly beneficial for if you are residing in noisy neighborhoods or along busy streets, as it creates a peaceful and serene atmosphere inside the building.

Strength

Concrete masonry produces some of the most robust and durable materials for construction. CMUs are weather-resistant and capable of handling heavy loads. They also provide protection from break-ins and fires, which can lower insurance rates for further cost savings.

Fire Safety

The CMU components—aggregates, water, and Portland cement—are non-combustible, and concrete has low thermal conductivity, so it does not transfer heat. In addition, it is non-toxic and does not react with other substances, so if there are gases or toxins involved in a fire, it will not ignite. These qualities make CMUs a safe construction option to protect people and belongings. However, exposure to extreme temperatures for a long time can impact structural integrity.

Mold and Moisture Resistant

CMUs are more effective for waterproofing than poured concrete. Mold can only grow in moist areas, so easy waterproofing is essential to keep structures safe and free of damage.

Low Maintenance

CMU requires virtually no maintenance over the decades, saving you money and giving back your free time that would otherwise be spent on painting, repairs, replacements, and upkeep.

Energy Efficiency

Masonry is naturally energy efficient and helps to keep your home cooler in the summer and warmer in the winter, helping to save you money on your energy bills.

Environmentally Friendly

Masonry is sustainably sourced from earth’s natural materials and is also 100% recyclable to be used in renovations, or new builds.

CMU Applications

CMUs can form the basis of many projects benefiting architects and end users. Due to their many benefits, CMUs are preferred for foundation, basement, partition, interior, and exterior walls. Additionally, finishes can prevent water penetration and complement space appearance, including epoxy, urethanes, and different paints.

CMU options suit many construction needs, from basic jobs to elaborate architecture.

• Ground face finish: Provides smooth finish, available in various colors.
• Split face finish: Features added depth and dimension for aesthetic appeal.
• Recycled: Made with recycled materials, available in many finishes.
• Polished block: Offers a highly polished finish highlighting aggregate’s natural beauty.

Examples of block types and their uses:

Concrete Blocks: A Sustainable Building Product

Most of the materials used to make CMU can be found locally. Waste products are used to produce concrete, diverting waste from landfills. Reduces CO₂ levels in concrete by up to 70 percent. Concrete is recyclable and can be reused in various ways. Reinforced steel in concrete can also be recycled.
