Studies show that brick homes command an average 6% higher resale price than non-brick homes, according to the Mason Contractors Association of America.
- Concrete masonry is the broad category that encompasses various types of masonry units, including solid concrete blocks, hollow blocks, and concrete bricks. In concrete masonry, Concrete masonry units (CMUs) are commonly used when constructing walls, partitions, and structural elements in residential and commercial buildings. These units are typically larger and denser in composition, providing greater structural strength and load-bearing capacity. When comparing strength in terms of psi, concrete blocks surpass bricks in durability. Concrete blocks can withstand an impressive 3,500 psi, surpassing the limit of bricks, which stands at 3,000 psi.
- Stone masonry is a construction method using stones and mortar. Renowned for their durability and strength, stones are one of the most robust and enduring building materials. Research shows that wildfires, heat waves, and droughts suffered throughout the U.S. from 2017 to early 2018 producing $12.33 billion in insured losses, according to the National Interagency Fire Center (NIFC). The stones are sourced from natural rocks, usually skillfully cut and shaped to fit the construction project's requirements.
- Block masonry is similar to concrete masonry but is a construction technique that utilizes concrete or cement blocks. These blocks are rectangular and can be either solid or hollow. Block masonry is known for its versatility and ease of construction, as the blocks can be easily stacked and interconnected using mortar. CMUs are usually much larger than bricks, meaning it is much quicker to build using this method. Masonry structures are commonly less to insure than wooden framed structures due to their resistance to damage, according to various law firms, thus saving even more money!
- Concrete bag masonry is when low-grade concrete mixture is carefully stacked in a pattern reminiscent of sandbags. These bags are then watered, transforming them into a series of interconnected artificial stones. The resulting structure seamlessly integrates into the surrounding soil and adjacent structures. Over time, the bags naturally disintegrate, rendering them non-functional. Concrete bag masonry safeguards water conduits' entrances and exits where roads traverse streams or dry washes. It also protects stream banks from erosion, especially near roadways. This innovative method effectively combines durability, practicality, and environmental sensitivity to provide reliable solutions for diverse construction challenges.
- Gabion masonry is the innovative use of wire-made baskets filled with medium-sized undressed stones. ‘Gabion’ comes from the Italian word gabbione, meaning ‘big cage’. These sturdy gabions are strategically stacked, forming a retaining wall. One of the key advantages of gabions is their exceptional drainage capability, where they can endure heavy periods of rain and flooding. It's important to note that their lifespan corresponds to the longevity of the wire they are composed of. In harsh climates, such as coastal areas exposed to saltwater, it is crucial to use corrosion-resistant wire to ensure longevity.
- Composite masonry is a construction technique combining two or more building materials, offering a range of advantages and opportunities. Firstly, it enhances the aesthetic appeal of the building, adding visual interest and uniqueness to its overall design. Moreover, composite masonry allows for the efficient use of available resources, promoting maximum economic benefits. In essence, composite masonry offers a harmonious fusion of materials, resulting in enhanced aesthetics and economic efficiency for construction projects.
- Reinforced masonry is a construction system incorporating steel reinforcement to enhance its structural integrity. Placing the reinforced bars or mesh within the mortar of CMUs or bricks allows much greater resistance to horizontal loads, including seismic forces. Reinforced masonry exhibits superior strength and remarkable capacity to withstand lateral loading compared to plain masonry (according to)
- Masonry veneer walls are a highly popular option for both new home construction and remodeling projects, desired for their ability to mimic the appearance of solid brick or stone walls while offering enhanced affordability and insulation. This versatile construction technique seamlessly integrates with traditional wood frame structures and can be applied to concrete block walls. Depending on individual preferences, masonry veneer walls can span an entire wall, extending from foundation to roof, or be selectively placed up to the window sill level. Its flexibility allows homeowners to achieve their desired aesthetic while optimizing cost-efficiency. Masonry veneer exemplifies the perfect blend of visual appeal, economic advantages, and insulation benefits, making it a preferred choice for those seeking both style and practicality in their residential projects.
- Glass block masonry is when units are made from glass that admits light but partially obscures internal and external views. Their exquisite beauty and resilience make glass blocks a standout choice in masonry, providing visual allure and structural integrity. The appearance of glass blocks can vary in color, size, texture, and form, and they exhibit a remarkable strength surpassing that of concrete. They can withstand the impact force of a car crash, according to Insider magazine. Their strength and durability require a different type of mortar (glass block mortar) to seal the units well and truly.

What Are the Types of Masonry Based on Bonding Material?
The bonding material used in masonry, or mortar, is a blend of fine sand and lime to create a mixture that offers remarkable flexibility, adhesion, and compressive strength. This mortar ensures a resilient and secure connection by serving as a reliable bonding agent between the individual units used in the structure. Its flexibility allows some absorption of natural movements within the building, preventing structural cracks. The long-lasting integrity of the house is preserved by the flexible bond that allows the natural shifting and settling that occurs over time to happen without damage.
The type of mortar used will affect which masonry technique is best suited.
Masonry in Cement Mortar
Masonry in cement mortar offers several advantages. It provides structural stability, with the cement mortar acting as a load-bearing element. It also enhances the resistance to external forces, such as wind, earthquakes, and other environmental factors. Additionally, masonry in cement mortar offers fire resistance and sound insulation properties, making it a preferred choice for residential and commercial construction projects.
Cement mortar is commonly used for brick and stone projects, reinforced brickwork, load-bearing structures, architectural work, and all work in moist situations.
Overall, masonry in cement mortar is a widely used construction technique that combines the strength of cement with the versatility of mortar, resulting in durable and aesthetically pleasing structures.
Masonry in Lime Mortar
The use of lime mortar in masonry can be understood when considering limestone forms 20% of the world's sedimentary rock, according to the British Lime Association. The abundance of this naturally occurring material made it perfect for construction for thousands of years. Some of the most iconic structures in history are made from lime mortar, including The Great Pyramids of Giza, The Coliseum, and The Parthenon.
Lime mortar is made by heating limestone to a high temperature. This process creates calcium oxide mixed with water to form lime mortar. Lime mortar possesses remarkable self-healing properties, gradually increasing hardness over time, making it more water-resistant and limiting mold and dampness. It also has the unique ability to absorb atmospheric carbon dioxide (CO2) continually. Although lime is still used today in many other practices, it has been replaced by the more durable and faster-setting Portland cement, but its historical value must be recognized!
