Hearting in brick masonry refers to the material used to fill the gaps between walls that have a stronger structural integrity, particularly in masonry construction. It’s essential for ensuring strength, stability, and durability in the overall structure. The term "hearting" originated from the practice of using rubble or debris from the trimming of face rocks as fill material, thus forming the crucial core or heart of the wall. This method allows for the efficient utilization of available resources while enhancing the structural integrity of the masonry wall.
What Is Hearting in Construction?
Hearting in construction refers to the material used as fill between walls of greater structural integrity, specifically in masonry applications. It serves as a supportive element that reinforces the strength and durability of the overall structure. The term “hearting” originated from the positioning of this material at the core or center of the wall, symbolizing the heart of the construction.
Typically, hearting consists of various materials, such as rubble or debris generated during the trimming of face rocks. Masons strategically utilize these waste materials to optimize their functionality within the wall. By carefully positioning the hearting material, masons ensure that it provides enhanced stability and strength to the structure, reducing the risk of structural failure or collapsing.
The interlocking arrangement of the hearting material helps distribute the weight evenly across the structure, preventing concentrated stress points. This aids in maintaining the overall integrity of the construction when subjected to external pressure, such as wind, seismic activities, or heavy loads.
Moreover, hearting plays a vital role in insulation. The voids created by the arrangement of hearting material within the walls contribute to better thermal insulation. This insulation property helps regulate the internal temperature of the structure, making it more energy-efficient and cost-effective, especially in regions with extreme weather conditions.
Skilled masons can utilize a combination of different-colored hearting materials to create visually appealing patterns or designs on the surface of the walls. This enhances the overall visual appeal of the structure while still providing the necessary support and strength.
It’s careful and strategic placement by skilled masons solidifies the construction, allowing for the creation of long-lasting and resilient structures.
When constructing a stone structure, hearting stones play a crucial role in maintaining it’s stability and longevity. These smaller stones are used to fill the gaps between the face stones, ensuring a tight and secure fit. By carefully packing the hearting stones within the wall without disturbing the alignment of the face stones, the structure becomes solid and resistant to collapse. Neglecting proper hearting can have detrimental consequences, compromising the integrity of the wall and potentially leading to a catastrophic failure.
What Are Hearting Stones?
Hearting stones, also known as packing stones, are an integral component in the construction of various structures. These smaller stones are used to fill the space between the two faces of a structure, providing stability and support.
When constructing a wall, it’s essential to pack the hearting stones as tightly as possible without displacing the face stones. This ensures that the structure remains solid and durable over time. Inadequate hearting can compromise the stability of the wall, causing it to collapse inward.
Hearting stones play a crucial role in balancing the weight distribution within a structure. By filling the gaps between face stones, they help evenly distribute the load and prevent excessive stress on individual components. This balancing effect is essential for maintaining the structural integrity of the wall.
It’s important to note that hearting stones should be carefully selected. They should ideally be of similar size, allowing for an even and compact placement. Additionally, the shape of the hearting stones should complement the structure, ensuring a proper fit and proper alignment.
Hence, it’s imperative to ensure a tight and secure placement of these stones to guarantee the durability and longevity of the structure.

The brick bond terminology refers to the different methods and patterns used to arrange bricks in a structure. These patterns can significantly affect the structural integrity, aesthetics, and overall strength of the construction. By understanding the various brick bond terminologies and their applications, builders and designers can create visually appealing and sturdy structures.
What Is Brick Bond Terminology?
There are several common brick bond patterns used in construction, each with it’s own distinct appearance and structural characteristics. One of the most basic and widely used brick bonds is called the stretcher bond, where bricks are laid in a simple pattern of alternating stretchers. This bond is commonly used in simple walls and provides a clean, uniform appearance.
This bond creates a more decorative pattern, with the headers creating a row of square faces on the exterior of the wall. Flemish bond is often used in more architectural and decorative applications.
In addition to these common brick bond patterns, there are also several more complex and decorative bonds, such as the herringbone bond and the basket weave bond.
These patterns not only provide aesthetic appeal but also play a crucial role in the structural integrity and stability of the wall or column. The choice of brick bond depends on factors such as the intended use of the structure, architectural design, and personal preference.

In addition to facing and hearting, another important element to be aware of when it comes to constructing walls is the side surface. This refers to the outer boundary of bricks or stones, positioned perpendicular to both the face and the bed of the wall. Understanding these various components is essential for building sturdy and aesthetically pleasing structures.
What Is Facing Backing and Hearting?
When constructing a wall, there are various components and terms to understand. One such element is facing, which refers to the material used on the visible side of the wall. Facing is responsible for providing aesthetics and enhancing the walls appearance. It can be made of bricks, stones, tiles, or other decorative materials. The facing acts as a protective layer, shielding the underlying structure from external elements such as weather conditions, moisture, and erosion.
In contrast, the hearting refers to the inner portion of the wall, located between the facing and the backing. It provides structural stability and strength to the wall. The hearting acts as a filler, creating a solid core between the facing and backing materials. It can consist of materials like loose stones, rubble, concrete, or mortar, depending on the construction technique and desired strength of the wall.
Apart from the facing and hearting, walls also have sides. The sides of the wall refer to the surfaces that form the boundaries of the bricks or stones used in the wall. While the face and bed refer to the front and bottom surfaces of the bricks or stones, the sides are the perpendicular surfaces. These sides contribute to the overall stability and structural integrity of the wall.
Whether it’s a decorative façade or a load-bearing structure, incorporating the right materials for the facing, hearting, and sides is essential for a successful construction project.
Conclusion
Comprising of material used as fill between sturdier walls, hearting plays a crucial role in maintaining the stability and solidity of the construction. By utilizing leftover rubble from the trimming of face rocks, masons cleverly repurpose these materials as hearting, effectively reducing waste and incorporating them back into the structure. This mindful approach not only promotes sustainability but also showcases the resourcefulness and skill of the craftsmen. The deliberate implementation of hearting further demonstrates the meticulous attention to detail and thoughtfulness necessary in creating durable and reliable brickwork.
