Brick masonry is a technique that has been used for centuries, providing strength and durability to various structures. One of the key elements in brick masonry is pointing, which refers to the process of filling the mortar between the bricks. While it may seem like a simple task, pointing plays a crucial role in the overall quality and integrity of a brick structure. In this article, we will delve into the details of pointing in brick masonry construction, discussing its purpose, types, materials, and best practices to achieve perfect pointing. Whether you are a builder, contractor, or simply interested in masonry construction, this article will provide you with all the essential information about pointing to help you achieve impeccable results.
Pointing is a technique used in brick masonry construction to fill the gaps between bricks or other masonry units with mortar or other material. It is an essential step in the construction process as it not only enhances the structural integrity of the building but also improves its aesthetic appeal. There are different types of pointing techniques used in brick masonry construction, each with its specific purpose and application. In this article, we will discuss the various types of pointing in brick masonry construction.
Flush Pointing: This is the most common type of pointing used in brick masonry. In this technique, the mortar is pressed into the joints and then leveled with the face of the bricks, leaving a smooth and flat surface. It is commonly used for interior walls and is suitable for bricks with a straight and smooth surface.
Raked Pointing: In this type of pointing, a V-shaped groove is created in the mortar joints using a raking tool. This technique is used for bricks with irregular surfaces or rustic appearance, as it gives a more textured and rustic finish. Raked pointing is commonly used for exterior walls and adds a decorative element to the building.
Tuck Pointing: Tuck pointing is a combination of flush pointing and raked pointing. In this technique, the first layer of mortar is placed in the joints and then raked, leaving a recess for the next layer of mortar. The second layer is then applied, flush with the face of the bricks, giving the illusion of narrow joints and a neat finish. It is commonly used for decorative purposes and is suitable for bricks with different sizes and irregular shapes.
Weather Pointing: As the name suggests, this type of pointing is used to protect the joints from harsh weather conditions. In this technique, the mortar is slightly recessed from the face of the bricks to prevent water from entering the joints and causing damage to the structure.
Struck Pointing: Struck pointing is similar to flush pointing, but instead of using a trowel, a wooden or metal strike is used to remove the excess mortar from the joints. This technique is commonly used for bricks with a rough or textured surface, as it gives a more rustic and natural finish to the joints.
V Pointing: In this type of pointing, the mortar is cut in a V shape inside the joints, leaving a triangular shape. This technique is commonly used for bricks with sharp edges and is suitable for both interior and exterior walls.
Extruded Pointing: In extruded pointing, a special pointing gun is used to apply the mortar in the joints. This technique is ideal for bricks with narrow joints, and it gives a neat and uniform finish to the joints. It is commonly used for decorative purposes and adds a modern touch to the building.
In conclusion, pointing is an essential aspect of brick masonry construction, and the type of pointing used depends on the type of bricks, location, and purpose of the building. It is crucial to select the appropriate type of pointing to ensure the structural integrity and aesthetic appeal of the building.
