What Is the First Step in Constructing a Masonry Wall
The first step in constructing a masonry wall is to calculate the number of bricks needed, accounting for mortar thickness.
Did You Know?
1. Unlike modern construction techniques, the first step in constructing a masonry wall is not laying the first brick. Instead, it involves preparing the foundation, which is crucial for stability and longevity.
2. An often overlooked but essential aspect of constructing a masonry wall is the use of mortar. This specialized mixture of cement, sand, and water provides the necessary adhesive properties to hold the bricks in place.
3. The process of constructing a masonry wall dates back thousands of years, with evidence of early masonry walls found in ancient Mesopotamia and Egypt. These walls were typically made using sun-baked bricks or stone blocks, depending on the available resources.
4. In traditional masonry construction, it is common to incorporate special bricks known as “corner bricks” at the edges of the wall. These bricks are specially shaped to provide stability and ensure a consistent angle and finish.
5. One lesser-known technique used in modern masonry construction is the use of “cavity walls.” These types of walls have a gap or cavity between two layers of masonry, which helps improve insulation and prevent moisture from permeating the structure.
Leveling The Foundation
In the construction of a masonry wall, the first step is to ensure a level foundation. This is crucial for maintaining the stability and integrity of the wall. A trench of recommended size, typically half a meter deep, should be dug to accommodate the foundation. The depth of the trench can vary depending on the height of the wall, with walls up to one meter in height generally requiring a half-meter deep trench.
Once the trench is excavated, it is important to level the foundation before proceeding with the construction. The first row of bricks, known as the footing course, should be placed in a manner that ensures they sit flush in the foundation. This level base is essential for proper alignment and stability of the entire wall.
Setting Up String Lines
To maintain consistent levelness in the construction of the masonry wall, gauging rods and string lines are utilized. After the foundation is leveled and the first row of bricks is laid, a piece of timber is cut to the height of the finished wall. This timber serves as a guidepost to determine the placement of each row of bricks.
The piece of timber is marked with 65mm lines, representing the vertical distance that each row of bricks should be placed apart. This ensures uniformity in the overall construction. String lines are then set up between the gauging rods to serve as placement guides for the bricks in the second row and beyond. These string lines provide a visual reference point, ensuring that the wall remains level as construction progresses.
Mixing Mortar
Mortar is crucial in masonry construction as it acts as the binding agent between the bricks. To mix mortar, an old damp board is commonly used as a mixing surface. The instructions provided by the mortar manufacturer should be followed carefully to achieve the desired consistency.
The mortar should have a firm texture that allows it to slip easily from the shovel. It is important to mix only the amount of mortar needed for immediate use, as leaving it to sit for too long can affect its effectiveness. Care should also be taken to avoid excess water when mixing mortar, as this can weaken the mortar and its bond with the bricks.
Laying The First Brick
With the foundation leveled and the mortar mixed, it is time to start laying the bricks. The first brick in the second row is often referred to as the second course. Mortar is placed on the foundation in a ‘v’ shape using a trowel. The brick is then pressed firmly into place and leveled, ensuring that it meets the string line. Any excess mortar is carefully removed.
After the first brick is correctly positioned, the process is repeated for each brick in the second row. It is important to consistently check for levelness using a spirit level to maintain the structural integrity and appearance of the wall. Additionally, a consistent mortar thickness of 10mm should be maintained between each brick, as this ensures proper bonding and strength.
Adding Finishing Touches
Once the brick wall reaches the desired height, several finishing touches can be added to enhance its visual aesthetics. Different joining patterns, such as a soldier course, can be used to create decorative elements within the wall. These patterns can add interest and personality to the overall design.
After all the bricks are in place, any gaps should be patched with mortar using a trowel. Excess mortar should be removed before it dries, using a soft brush to avoid damaging the surface of the bricks. It is important to clean up any mortar on the ground to maintain a tidy appearance.
To protect the wall from rain or frost during the initial stages of drying, a tarp or polythene sheet can be placed over the top overnight. This precautionary measure is generally only necessary for the first night of the construction process.
If the goal is to match the new brick wall to existing brickwork, additional steps, such as tinting or weathering the brickwork, may be required. These processes can be addressed by using a code from the original brick purchase, which ensures a consistent visual appearance throughout the entire project.
In conclusion, constructing a masonry wall involves several important steps that should be followed carefully. From leveling the foundation and setting up string lines to mixing mortar and laying the bricks, attention to detail and precision are essential for a successful project. Adding finishing touches and taking necessary precautions for protection from the elements completes the process, resulting in a durable and visually appealing masonry wall.

Frequently Asked Questions
What is the process of masonry construction?
The process of masonry construction begins by carefully selecting and preparing the materials to be used, such as bricks, stone blocks, or concrete blocks. These materials are then stacked in a precise manner, with mortar being applied between each layer to create a strong, durable bond. Masons use their expertise to ensure that the structure is built to specification, paying attention to details such as levelness and proper alignment. Throughout the construction process, the masons continuously monitor and adjust the placement of the materials, ensuring that the structure is sturdy and aesthetically pleasing. The result is a solid, visually appealing structure built to stand the test of time.
What are the basic principles of masonry construction?
The fundamental principles of masonry construction involve ensuring the quality and preparation of bricks before their use. First and foremost, bricks should be well burnt and consistent in size to guarantee their structural reliability. Secondly, when laying bricks with cement or lime mortar, it is essential to properly soak them in water for a minimum of two hours before incorporating them into the construction process. This soaking process enhances the bond between the bricks and the mortar, resulting in a stronger and more durable masonry structure.
What are the elements of masonry construction?
Masonry construction encompasses various elements that form the core of a structural element. These elements primarily consist of masonry units composed of diverse raw materials such as clay, mud, concrete, calcium silicate, and stone. Masonry units serve as the fundamental building blocks, lending strength and durability to the construction. These materials are meticulously selected and combined to create cohesive structures that withstand the test of time. Whether it be the classic charm of stone or the versatility of concrete, the elements of masonry construction offer a diverse range of materials for building robust and visually appealing structures.
What is masonry wall construction?
Masonry wall construction is a traditional building method that utilizes materials like brick, stone, or concrete blocks to erect walls. These materials are carefully stacked one on top of the other and held together with a bonding agent called mortar. This ancient technique has been employed for centuries in the construction of various buildings and structures, showcasing its time-tested durability and aesthetic appeal. Whether it’s the timeless beauty of brick walls or the sturdy elegance of stone structures, masonry wall construction stands as a testament to the ingenuity and longevity of this age-old building system.
