Different Types of Masonry Walls: Know Definition, Types & Applications

Masonry walls are structural elements composed of individual units, such as brickwork, stones, concrete blocks, or other materials, joined together to form a wall. These walls play a crucial role in construction, providing structural support, enclosing spaces, and contributing to the overall aesthetics of a building. The type of masonry wall chosen often depends on factors such as the materials used, construction techniques, and desired characteristics. There are various types of masonry walls, each with its own unique features and applications, catering to the diverse needs of construction projects.

This blog uncovers all the important details regarding the different types of Masonry walls. This topic is important for all the upcoming Civil Engineering Examinations, including SSC JE CE and RRB JE Civil.

What is a Masonry Wall?

Masonry walls are durable structures constructed using mortar as a bonding material with individual units. These units can be bricks, building stones, or concrete blocks. Masonry, in construction, involves using mortar as a bonding material with individual units like bricks, stones, marbles, rocks, concrete blocks, tiles, and more. Mortar plays an invaluable role in Masonry walls. It is a mixture of binding material with sand. Binding materials can include cement, lime, soil, or other construction materials. 

Types of Masonry Wall

The different types of Masonry walls are:

• Load-bearing masonry wall
• Reinforced masonry wall
• Cavity masonry wall
• Composite masonry wall
• Post-tensioned masonry wall

Load-bearing Masonry Walls

Load-bearing masonry walls are made of bricks, stones, or concrete blocks. These directly transmit the loads from the roof to the foundation. They serve as both exterior and interior walls, providing an economical construction system compared to framed structures. The thickness of these walls is determined by the load they bear, with variations based on the number of floors and occupancy type. It is pertinent to note that Load-bearing walls can be either reinforced or unreinforced masonry walls.

Reinforced Masonry Walls

Reinforced masonry walls, whether load-bearing or non-load-bearing, incorporate reinforcement to enhance their ability to withstand Tension Force and heavy compressive loads. Unlike unreinforced masonry walls, which are susceptible to cracks and failure under substantial loads or seismic activity, reinforced walls provide improved resistance. They are particularly effective in countering lateral forces during adverse weather conditions like heavy rain and wind. The incorporation of reinforcement, strategically placed at necessary intervals both horizontally and vertically, is determined based on the specific loads and structural conditions the walls are expected to endure.

Cavity Masonry Walls

Hollow or Cavity masonry walls serve the purpose of preventing moisture infiltration into the building's interior by creating a hollow space between the exterior and interior faces of the wall. Additionally, these walls contribute to temperature control within the building by impeding the transfer of heat energy from the outside wall, thanks to the insulating effect of the hollow space.

In instances where the wall is exposed to moisture over an extended period, and water permeates the outer face, it reaches the cavity or hollow space and then moves downward. The water is subsequently drained through designated weep holes to the exterior of the building. To further minimize moisture ingress, these hollow spaces may be coated with water repellent coatings or damp-proofing materials.

Composite Masonry Walls

Composite masonry walls incorporate two or more masonry units, including stones, bricks, and hollow bricks, to achieve a visually appealing yet economical construction. This type of wall construction involves the bonding of two wythes of masonry units. One wythe can consist of brick or stone masonry, while the other may be composed of hollow bricks. A wythe refers to a continuous vertical section of masonry one unit in thickness. The connection between these wythes is established through horizontal joint reinforcement or the use of steel ties.

Post-tensioned Masonry Walls 

Post-tensioned masonry walls are built to enhance the strength of the walls against force that might cause tension, such as earthquakes or wind. Construction starts from the foundation level, with post-tensioning rods anchored into the foundation. These rods run vertically between the wythes or within the core of concrete masonry units. After completing the masonry wall construction and allowing it to cure, the rods are tensioned and anchored on the steel plate at the top of the wall.

Applications of Masonry Walls

Masonry walls, constructed from materials like brick, stone, concrete blocks, or other masonry units, are widely used in construction due to their durability, strength, and aesthetic appeal. These walls offer a variety of applications in both residential and commercial buildings. Here are some of the key applications of masonry walls:

Structural Support

• Load-bearing Walls: Masonry walls are commonly used as load-bearing walls in buildings. These walls help support the weight of the structure above, including floors and roofs. Due to their strong compressive strength, masonry is an ideal material for this purpose.
• Foundation Walls: Masonry is often used for foundation walls in buildings. The strength and durability of masonry make it suitable for bearing the load of the entire structure while resisting soil pressure and moisture penetration.

External and Facade Walls

• Building Exteriors: Masonry is commonly used for the exterior walls of buildings due to its aesthetic appeal, strength, and resistance to weathering. Brick, stone, and concrete blocks are often used for facades, giving buildings a durable and attractive appearance.
• Weather Resistance: Masonry walls offer excellent protection against the elements, including rain, wind, and snow. The density of the materials provides insulation, and when properly sealed, masonry walls are highly weather-resistant.

Fire Protection

• Firewalls: Masonry walls are fire-resistant, making them ideal for constructing firewalls in both residential and commercial buildings. These walls help prevent the spread of fire from one section of the building to another, providing an essential safety feature.
• Fire-Rated Partitions: Masonry walls are used to create fire-rated partitions that can withstand high temperatures and prevent the spread of flames and smoke in case of a fire.

Acoustic Insulation

• Soundproofing Walls: Due to their mass and density, masonry walls offer excellent soundproofing properties. They are commonly used in areas where sound insulation is important, such as in recording studios, concert halls, or office buildings.
• Internal Partition Walls: In multi-unit residential buildings or commercial spaces, masonry partition walls help in reducing sound transmission between rooms or units.

Energy Efficiency

• Thermal Insulation: Masonry walls, particularly thick ones, provide natural insulation. Materials like brick and stone have high thermal mass, meaning they can absorb and store heat during the day and release it at night, helping to regulate indoor temperatures. This leads to energy savings in heating and cooling.
• Passive Heating and Cooling: In climates where temperatures vary greatly between day and night, masonry walls can contribute to passive heating and cooling by reducing the need for artificial temperature regulation.

Retaining Walls

• Soil Retention: Masonry is used in the construction of retaining walls to hold back soil, preventing erosion, and maintaining the integrity of sloped land. These walls are essential in landscapes with steep gradients or areas prone to soil movement.
• Landscaping and Garden Walls: Stone or brick masonry is often used for garden walls and landscaping features due to its aesthetic appeal and ability to withstand environmental conditions.

Interior Walls

• Partition Walls: Masonry is used for interior partition walls to divide spaces within a building. It provides a durable, fire-resistant, and soundproof solution, making it suitable for both residential and commercial buildings.
• Basement Walls: In basements, masonry walls offer high resistance to moisture and provide a strong barrier against water seepage. Concrete masonry units (CMUs) are often used for basement walls due to their durability and water resistance.

Decorative Features

• Accent Walls and Features: Masonry can be used for decorative accent walls in interiors or exteriors, using materials like brick, stone, or textured concrete. This adds visual appeal and texture to the building’s design.
• Arches and Vaults: Masonry is often used in the construction of arches and vaults, which are architectural features that require the compressive strength and stability that masonry materials provide.

Historic and Heritage Buildings

• Preservation of Historical Structures: Many historical and heritage buildings are constructed using masonry walls, and masonry remains an essential material in the restoration and preservation of such structures. The materials and techniques used in traditional masonry construction are often retained to maintain the authenticity of the building.
• Monuments and Memorials: Masonry, especially stone, is commonly used in the construction of monuments, memorials, and statues due to its durability and timeless aesthetic qualities.

Security Walls

• Perimeter Fencing: Masonry walls are used to build secure perimeter fences around properties, especially in commercial, industrial, or high-security residential areas. These walls offer both security and privacy.
• Protection Against Intruders: The strength and height of masonry walls make them difficult to breach, providing a secure barrier against potential intruders or unauthorized access.

Seismic Resistance

• Earthquake-resistant Walls: When designed and reinforced properly, masonry walls can provide stability during seismic events. For example, reinforced brick masonry (RBM) or reinforced concrete masonry can be used in earthquake-prone regions to offer resistance to lateral forces caused by ground shaking.
