This pointing method is commonly used in brick walls that are exposed to harsh weather conditions. The concave shape of the mortar helps in directing the rainwater away from the bricks, preventing water penetration and damage.

3. Recessed Pointing: Also known as ‘Raked’ pointing, this method involves removing a portion of the mortar from the joint, leaving a recessed groove. The mortar is usually raked to a depth of 10-12 mm, and the remaining depth is filled with a suitable sealant. Recessed pointing is commonly used in structures where the appearance of the mortar is not a significant factor, but weather resistance is essential.

4. Vee Pointing: As the name suggests, this pointing method forms a V-shaped groove in the joint. The brick edges are filled with mortar, and a flat joint is produced. This type of pointing is usually used in low-stress structures as it provides minimal protection from the weather.

5. Tuck Pointing: In this technique, two different colors of mortar are used to fill the joints between brickwork. The first layer consists of a suitable base mortar, and the second layer is a thin layer of colored mortar. The edges of the bricks are first filled with the base mortar, and then a colored mortar is applied on top, creating a contrast. Tuck pointing is mostly used for decorative purposes.

6. Struck Pointing: In this method, the joints are filled with a flush mortar finish, and the excess mortar is struck back into the joints with a tool. This pointing technique is often used for buildings with a more rustic and natural look.

In conclusion, each type of pointing method offers a specific structural and aesthetic benefit, and the choice of method depends on the type of structure, site conditions, and desired appearance. Consulting a professional civil engineer is advisable to select the most suitable pointing method for a particular project.
