Which of the following is NOT a benefit of using welded wire reinforcement?

Welded wire reinforcement is widely recognized in construction for its various advantages, specifically in enhancing the performance of concrete structures. One major benefit is increased resistance to cracking. This aspect is critical because concrete can shrink and crack during curing; using welded wire helps mitigate this risk by providing tensile strength.

Another significant advantage is improved structural integrity, as the reinforcement helps to maintain the shape and strength of the concrete under load, thus providing greater durability over time. Moreover, welded wire reinforcement facilitates enhanced load distribution across the concrete slab, which helps in managing stresses more effectively.

While welded wire does offer substantial benefits, it can lead to higher labor costs if not implemented efficiently or if the installation requires more complex labor techniques. However, this characteristic is a cost implication rather than a benefit of the reinforcement method itself. Thus, the answer identifying higher labor costs aligns with being the option that does not represent a benefit of using welded wire reinforcement.
