What does "joint reinforcement" involve in masonry?

Joint reinforcement in masonry specifically refers to the practice of using metal reinforcing bars, often known as wire reinforcement, placed within the mortar joints of masonry walls. This technique significantly enhances the structural integrity of the wall by providing additional tensile strength, which helps to resist cracking and other structural failures caused by loads, temperature changes, or settling.

The inclusion of these metal bars increases the overall strength of the masonry assembly, making it more capable of handling stress. This reinforcement is particularly crucial in large walls or structures that will bear heavy loads or are exposed to harsh environmental conditions.

While there are other methods and materials that can be used for decorative purposes, waterproofing, or aesthetic enhancements in masonry, none of these practices involve the functional aspect of joint reinforcement as defined by the use of metal bars for structural improvement. Therefore, understanding that joint reinforcement is fundamentally about enhancing the mechanical performance of masonry is key to recognizing its significance within construction and building practices.
