Masonry is a construction technique that utilizes brick, stone, marble, granite, concrete blocks, or other materials held together by mortar. The material and quality of masonry construction determine its longevity and strength.
A high degree of uniformity and accuracy in the brickwork was typical in buildings built in earlier periods. This was thought too sterile in later years, and attempts were made to emulate older, rougher work.

Most masonry work gets a lot of attention for the bricks and stones used in the project. Different strands, restored bricks, and granite often receive the spotlight, but the mortar holds these materials together. Without strong mortar, a beautiful brick wall or a majestic stone mantle could be doomed to collapse down the road. Mortar comprises sand and a binder such as cement or lime. Depending on the type of masonry project, specific ratios of these materials provide varying results.
Most masons are familiar with the differences between mortar types and their compressive strengths, but some may need to realize that there are also mortar categories. Choosing the right category for a particular application can greatly impact the longevity of the walls or structures built with it.
For example, mortar-rated CM-1 is low-strength and ideal for soft stone and stone blocks because it can flex to absorb the stress from the movement of these materials. However, if a mason uses CM-1 mortar on an above-grade load-bearing wall, the wall might crack because it is not designed to support the weight of this structure.
Generally, mortar should be mixed with water until it is stiff enough to hold its shape when troweled on the surface. During this process, the mason should also check the mortar’s water retention characteristics. If the mortar loses its plasticity too quickly, it won’t be easy to bed and adjust the concrete masonry units that are being placed. Ideally, the mortar should retain its workability for at least an hour so that masons can continue to lay masonry units as fast as possible.
Masonry professionals typically prefer to mix their mortar for each job because it allows them to create a custom balance to achieve the desired results. However, premixed mortar is available and can save a lot of time by providing masons with an ideal mixture ready to use as soon as it is mixed. Premixed mortar can also be a great choice for homeowners looking to repair their existing masonry walls.
Concrete blocks are versatile building materials used in various projects and styles. They are often more cost-effective than poured concrete and can be molded into many shapes and sizes, including custom designs. They also have a natural aesthetic and are highly durable. They can help reduce energy usage and provide building occupants with a more comfortable indoor environment. These blocks can be stacked to create a variety of decorative façades, and they can play with light to transform exteriors.
Concrete Blocks are manufactured from a mix of cement, aggregate (usually sand or crushed stone) & water. The mixture is shaped into a block using molds & vibrated or hydraulically compressed. They are then cured in a kiln under controlled temperatures, pressures & cycles. The curing process is critical to the strength of the finished product.
CMU walls are durable and fireproof, making them an excellent choice for commercial and residential structures. They can be built in a variety of shapes and can also serve as the structural frame for a wall veneer. They also have the added benefit of mitigating energy usage and reducing heating and cooling costs, resulting in lower overall energy bills for the building’s occupants.
The type of block chosen will depend on the desired properties of the final structure. For example, a “solid” block is generally preferred when higher fire resistance or sound absorption is required. These blocks are typically made from aggregates rich in silica and alumina, making them suitable for load-bearing walls.
Hollow concrete blocks are available in different shapes & sizes depending on their position or function within the wall. These include concrete stretcher blocks, lintel blocks & partition concrete blocks. Corner concrete blocks & pillar concrete blocks are also commonly used.
Some blocks are even designed with a rough, stone-like texture, giving them the architectural look of cut and dressed stones. Various colors are also available to match a project’s design and color palette. This allows architects and designers to build practical and visually appealing structures.
A masonry wall is an essential building component that provides stability and strength to the entire structure. It also acts as a protective barrier that regulates the temperature inside the building and keeps moisture out. It can be made from stone, brick, concrete blocks, or a combination of these to suit the construction project’s needs.
A typical masonry wall comprises several components: the face, backing, hearting, and joints. A face is the part of a wall visible to the outside world, while the backing is the internal section of the wall. Hearting is the layer of masonry materials sandwiched between the faces and the backing, providing stability to the whole wall. The joints are where bricks or stones join and can be sealed with cement or lime mortar.
Masonry walls are generally thicker at the base to resist the forces of gravity and the dead and live loads of floors and roofs. A traditional load-bearing masonry wall can also be buttressed to increase its strength. These are reinforced with steel bars or concrete.
While masonry has a good compressive strength, it can be very weak in tensile strength, especially if unreinforced. This weakness can lead to cracking under heavy strain or during earthquakes. Reinforced masonry walls, on the other hand, are designed to withstand both strain and tensile stresses. The tensile strength of masonry can be increased by increasing its thickness or by building masonry piers, also known as ribs, at intervals. It can also be strengthened by adding rebar to the wall and grouting them solidly.
Masonry can also be built as post-tensioned walls to improve their resistance against seismic and wind forces. This is done by introducing post-tensioning rods to the foundation and anchoring them to the wall’s core. The structure’s design and structural circumstances determine these rebars’ size, number, and spacing.
Masonry walls can be constructed using various materials, from age-old burnt clay bricks to the latest in masonry materials such as Autoclave Aerated Concrete (AAC) and fly ash bricks. These modern masonry materials are lighter and have a higher compressive strength than their older counterparts. They can also be manufactured on-site to save costs in transportation and taxes.
Masonry is a highly durable building material that requires little maintenance and is less expensive to repair than other structures. In addition, masonry offers insulating properties that can significantly lower energy costs in a home or business. Masonry can be built in various styles, including brick, stone, and concrete.
A masonry foundation is a structural component that transfers the weight of a structure to the soil so as not to exceed the ultimate bearing capacity of the soil and prevents lateral movement. It is constructed from a mixture of stone or bricks, concrete blocks, cement mortar, or other suitable materials. A professional engineer typically designs masonry foundations.
Poured concrete foundations are the most common type of masonry foundation. They are built by erecting forms and pouring a concrete mix into the form. A concrete mix must be free of air bubbles and water puddles to ensure proper strength. Depending on the climate, adding insulation to the foundation may also be necessary to reduce heating and cooling bills.
Another masonry foundation is the strip footing, a continuous slab strip along the length of a wall. It can be made from stone, brick, or reinforced concrete. The size of a strip footing depends on the height of the wall above, its location, and the soil condition under the foundation. If the soil is loose, a deeper foundation should be used.
The block foundation is an alternative to the strip footing. It can be made from brick, cinder concrete (“cinder blocks” or “breezeblocks”), or ordinary concrete (concrete blocks). It is generally faster to construct than brick masonry and has a much greater resistance to moisture penetration. It is often used in commercial or industrial construction.
The stepped footing is a special type of strip footing. It is used when there is a risk of settlement due to the action of a horizontal vector. The vertical steps in the footing distribute the load over a larger soil area, resulting in a smaller settlement. It is also important that a stepped footing be constructed with sufficient depth to avoid heaving of the soil.
