Where Is Reinforced Masonry Used
Reinforced masonry is commonly used in structures where the brickwork needs to bear shear stress, increase longitudinal bond, and carry heavy loads.
It utilizes a network of steel meshed strips called exmet, which is embedded in dense cement mortar to strengthen the masonry and prevent cracks.
The reinforcement is typically supplied in coils of 83m length and helps prevent the expansion of joints due to corrosion.

Introduction To Reinforced Masonry
Reinforced masonry is a construction technique that involves the use of a network of steel meshed strips called exmet to reinforce brickwork. By embedding this reinforcement in the masonry, it becomes stronger and more resistant to cracks, allowing it to bear shear stress and carry heavy loads.
The key to its strength lies in the use of dense cement mortar, which securely holds the exmet in place and prevents corrosion.
In this article, we will explore the various applications of reinforced masonry and the benefits it offers in different construction scenarios.
Exmet: The Steel Mesh Strips In Reinforced Masonry
Exmet, short for expanded metal, is a form of steel mesh commonly used in reinforced masonry. It is supplied in 83-meter coils, providing sufficient material for various construction projects. This mesh is created by cutting and stretching sheet metal, resulting in a grid-like pattern of interconnected strands. The unique design of exmet allows it to distribute load-bearing forces across a larger area, thereby enhancing the stability of the masonry. Moreover, its flexibility enables it to conform to irregular surfaces, making it an ideal choice for reinforcing brickwork in complex architectural designs.

Embedding Reinforcement With Dense Cement Mortar
In reinforced masonry, the exmet reinforcement is embedded within the brickwork using dense cement mortar. The process involves carefully layering the bricks and exmet, ensuring that the reinforcement is strategically placed to withstand the anticipated loads and stresses. The dense cement mortar, composed of cement, sand, and water, is then applied to encase the exmet, creating a solid bond between the reinforcement and the brickwork. This embedding process not only strengthens the masonry but also helps to prevent cracks by evenly distributing the forces exerted on the structure.
Preventing Cracks And Strengthening Reinforced Masonry
One of the primary benefits of reinforced masonry is its ability to prevent cracks and strengthen brick structures. The exmet reinforcement acts as a support system, absorbing and dispersing the forces applied to the masonry. This reinforcement enables the brickwork to resist shear stress, which is a common type of stress that occurs when two different materials try to slide past each other.
Reinforced masonry is commonly employed in situations where the brickwork needs to bear heavy loads, such as in the construction of:
- Bridges
- High-rise buildings
- Industrial structures
By reinforcing the masonry, these structures can safely carry the required weight and remain structurally stable over time.
“Reinforced masonry plays a crucial role in ensuring the strength and durability of brick structures.”
Importance Of Preventing Corrosion In Reinforced Masonry
While reinforced masonry offers significant strength and durability, it is crucial to prevent corrosion in the steel reinforcement. Corrosion occurs when the exmet is exposed to moisture and air, causing it to rust and deteriorate. This not only weakens the reinforcement but also leads to the expansion of joints in the masonry, potentially compromising the structural integrity of the entire building.
To prevent corrosion, protective measures can be taken, such as applying waterproof coatings to the exmet or using stainless steel reinforcement, which is highly resistant to rust. Regular inspections and maintenance are also essential to identify and address any signs of corrosion, ensuring the continued strength and stability of the reinforced masonry structure.

Frequently Asked Questions
Why reinforced brick masonry is used?
Reinforced brick masonry is utilized for its ability to enhance the structural integrity and durability of brick walls. The inclusion of brick reinforcement mesh effectively strengthens the masonry, offering additional resistance against settlement and minimizing the occurrence of local cracking. However, relying solely on brick reinforcement may be insufficient in reinforcing a brick wall comprehensively, as it may not provide adequate support against wider, overall cracking. Therefore, reinforced brick masonry is employed to ensure the longevity and stability of the structure, mitigating potential damages and prolonging its lifespan.
What is reinforced brick work where it is used?
Reinforced brickwork is a type of construction technique that utilizes bricks combined with reinforcement materials to enhance its strength and durability. This method is commonly employed in situations where the brickwork needs to withstand shear stress, improve the longitudinal bond, and bear significant loads. By incorporating reinforcement, such as steel bars or mesh, into the brickwork, the structure becomes better equipped to handle these challenges and ensure the stability and longevity of the construction. This technique is particularly useful in building walls or structures that are expected to endure heavy loads or external forces over time.
Where is masonry used in construction?
Masonry is extensively used in construction for various purposes. One common application of masonry is in the formation of load-bearing walls in buildings and structures. These walls provide structural support and contribute to the overall stability and strength of the construction. Additionally, masonry is used for constructing non-load bearing elements such as partition walls and cladding, which enhance the aesthetic appeal and functionality of the structure. From houses to bridges and tunnels, masonry finds its place in a wide range of construction projects, combining durability and design seamlessly.
What is masonry commonly used for?
Masonry is commonly used in construction to build a diverse range of structures such as houses, buildings, and even historical landmarks. Its versatility and aesthetic appeal make it a popular choice for creating durable and visually appealing facades. Furthermore, masonry’s inherent fire resistance and ability to withstand extreme weather conditions like high winds and earthquakes contribute to its widespread use in ensuring the safety and longevity of structures. Overall, masonry provides an excellent combination of durability, low maintenance requirements, and cost-effectiveness, making it a trusted choice in various construction projects.
