Final answer:
Low-lift grouting in masonry walls provides additional strength and stability to the structure. It fills gaps and provides uniform support, increasing load-bearing capacity and reducing the risk of failure.
Step-by-step explanation:
Some architects and engineers prefer to specify low-lift grouting in masonry walls because it provides additional strength and stability to the structure. Low-lift grouting involves pumping grout, a mixture of cement, sand, and water, into the cavities and voids in a masonry wall. This helps to fill any gaps and provides uniform support to the wall, increasing its load-bearing capacity and reducing the risk of structural failure.
By using low-lift grouting, architects and engineers can ensure that the masonry walls are able to withstand the immense pressure exerted on them, particularly in tall buildings or structures with heavy loads. This technique also helps to improve the overall durability and longevity of the masonry walls, as it minimizes the risk of cracking, shifting, or settling over time.
