Brick and stone are strong, long-lasting materials that withstand harsh weather conditions. They also help control sound and save energy costs by insulating against daily temperature fluctuations.

Concrete is one of the primary building materials used in masonry construction. It is poured in place or formed by combining cement with other material such as sand or recycled aggregates, fly ash, ground granulated blast furnace slag (GGBS) and limestone fines to create the mortar that holds bricks, blocks, stones and other masonry units together. Concrete is durable, aesthetically pleasing and can be shaped to fit the interior or exterior of a structure.

Masonry can be poured on site or precast in a factory setting to ensure proper consistency and quality. Using precast concrete offers a more efficient construction process because floor planks can be placed quickly and mechanical, electrical and plumbing contractors can begin work on the building immediately. Load-bearing masonry buildings constructed with concrete block, brick or stone can be as high as 28 stories.

Compared to steel or metal frame construction, masonry is a safer and more cost-effective building system. Its non-combustible nature means fewer fires and lower insurance rates. In addition, masonry structures do not rust or change color over time, which can save maintenance and replacement costs over the life of the building.

Most masonry structures provide a high level of sound control for multi-family dwellings, hotels and dormitories, and are the preferred method of constructing partition walls. Masonry also offers a good level of thermal mass for efficient heating and cooling, especially when insulated.

The insulating properties of masonry make it ideal for new residential homes and for retrofitting existing homes. However, masonry can be difficult to insulate as it tends to expand and contract with temperature changes. In addition, it is often more expensive than a wood frame wall with insulation. Masonry construction is also labor intensive, which can increase the overall project timeline compared to other construction methods. It can also be heavy, requiring more substantial foundation designs to support the weight. This can have a negative impact on construction costs, particularly in tight spaces where movement is restricted.


Masonry involves the construction of structures with stone and bricks. It is one of the oldest construction techniques, and has been used for centuries to create long-lasting buildings that can withstand extreme weather conditions, earthquakes, and fires. Some of the most famous works of masonry are the pyramids at Gobekli Tepe, the Parthenon, and Angkor Wat. Those who choose to become a mason need years of practice and training to develop their skills, but it is a rewarding career for those with the right aptitude. Masons must be able to work well under pressure, have a keen eye for detail, and be comfortable working at heights. They must also be able to use a variety of tools, including hand-held and power-driven hammers, mallets, and chisels.

The strength of a masonry structure depends on both its material and its mortar. Its material must be durable enough to resist both chemical reactions and thermal expansion and contraction. The mortar must be strong enough to hold the stones together, while still remaining soft enough to allow for flexibility and movement.

Stone masonry uses a variety of materials, but is most commonly made from sedimentary rocks such as limestone and sandstone. These rocks are created when mineral grains are deposited in a basin after being carried there by wind, water, or ice. These grains are then bonded together by natural processes such as weathering, to form a sedimentary rock.

When building with stone, masons must carefully measure and cut each piece of rock to fit it into place. This is a labor-intensive process, but it results in a wall that is both sturdy and beautiful. Masons can also use stone to build features such as lintels over windows and doors, and flat arches.

Masons also use concrete blocks to construct walls. These are more durable than bricks, and can be prefabricated to reduce construction time on site. They can also be used to meet higher standards of energy efficiency in newer buildings.

While concrete has replaced traditional masonry, it is possible to make unreinforced stone shear walls that can resist seismic loads. These walls must be designed using a specific formula that takes into account the ductility of the material and its ability to dissipate energy.


Brick is a building material that is clay-based, and can be mixed with other materials to create different colors and textures. It is commonly used for structural foundations, walls, exposed brick and pillars. It can also be painted to achieve a specific design or style. Brick masonry is a durable, cost-effective construction method that can withstand the elements and provides strength and resilience for a wide range of uses.

There are many types of bricks, and they can be classified based on their size, forming method, color, origin, texture and quality. Some common types of brick include soft mud, dry press and extruded. Soft mud bricks are made from slightly moistened local soils that are compacted with a hydraulic press or manual lever press and may have a small amount of cement binder added to increase their strength. Dry press bricks are made from a thicker clay mixture that is compressed with a greater force and a steel die to create the required shape. The bricks are then fired in an oven to increase their strength.

As climate changes, masonry structures must endure the increased pressure of extreme weather conditions. During freeze-thaw cycles, bricks can develop cracking and spalling. To reduce the risk of damage, builders should ensure that their masonry is properly constructed and use a high-quality, water-resistant mortar.

While brick masonry is highly durable, it can be difficult to work with due to its density and weight. It requires skilled labor and specialized equipment to install, which can increase the construction time and costs of a project. In addition, masonry materials are susceptible to moisture, which can lead to mold growth and water damage. To protect masonry from these problems, builders should seal the surface regularly with a hydrophobic sealant to keep it free of dirt and algae.

Brick masonry is laid in a number of different bonding patterns, which determine the wall’s thickness and overall strength. One popular type of masonry is header bond, which features bricks with their smaller square heads facing up. When laying header bricks, it is important to maintain proper spacing and alignment. The space between each brick should be roughly half of the brick’s width. When using this type of bond, builders should use a level to ensure that the wall is plumb and straight.


Reinforcement is required for masonry walls to hold up to the pressures of flexural and shear stresses. This is a critical factor in the stability of masonry buildings and structures, especially when subject to geological or weather hazards like earthquakes and hurricanes. In un-reinforced masonry, one wall or the entire building could collapse under such conditions. Building codes across the country require varying levels of reinforcement for each masonry material, size and function.

Reinforcing is most often made from carbon steel and comes in a wide variety of sizes and shapes. The most common is the round, deformed bar with a plain surface that’s a little over an inch in diameter, commonly referred to as “pencil bar.” Other types of rebar include ladle-welded or bent bar, trough-weld bar, and special rebar for use in seismic construction. It can also be made of other materials, including stainless steel for projects in which the structure may be exposed to corrosive elements like salt water.

There are different grades of rebar, with yield and tensile strengths that determine how much stress it can withstand. The higher the tensile strength, the stronger the bar will be. The yield strength is the minimum amount of stress that a rebar can sustain before it begins to permanently deform.

Generally, the larger the diameter of the bar, the more strength it will have. For example, #4 bar is a lot more durable than #2 bar, although both will provide adequate support in a structure. It’s important to understand these differences when selecting the correct rebar for any given project.

The length of the bar also plays a role in its durability. For instance, the length of overlap between bars in a wall is crucial to the integrity of the structure. The length of the overlap varies by engineering design but is usually at least 1/8 of an inch.

To ensure that the rebar is properly placed, a structural fabricator will typically embed it in the mortar joints of the wall. They’ll do this periodically along the length of the wall, using a tool called a bar positioner.
