What is the purpose of using sleeving in construction?

Using sleeving in construction primarily serves the purpose of protecting penetrations in concrete. Sleeving is typically a tubular casing installed in concrete structures to allow for the safe passage of pipes, wires, or other utilities. The sleeve provides a barrier that safeguards these installations from direct contact with the concrete, which can be abrasive and may cause damage over time. By using sleeving, builders can ensure that utilities are less likely to be compromised by environmental factors or structural shifts.

Additionally, sleeving helps facilitate the installation process. It allows for easier access to utilities when modifications or repairs are necessary, as the sleeve provides a clean and defined pathway through the concrete. This feature is particularly beneficial in structural scenarios where concrete is poured around existing infrastructure, reducing the risk of cracking or damaging important elements during installation.

In contrast, while the other options may relate to construction techniques, they do not specifically address the primary function of sleeving in protecting penetrations in concrete. For instance, ensuring visibility of utility paths, providing flexibility for movement, or supporting heavy fixtures pertain to different aspects of construction practices and do not capture the essence of what sleeving is designed to accomplish.
