What is an important consideration when installing rebar within a concrete form?

When installing rebar within a concrete form, ensuring that the rebar is within the specified cover requirements is essential for several reasons. The cover, which is the distance between the surface of the concrete and the rebar, plays a vital role in protecting the rebar from environmental factors that can cause corrosion, such as moisture and chlorides. Adequate cover also contributes to the overall strength and durability of the concrete structure, as it ensures proper bonding between the concrete and the rebar. By adhering to specified cover requirements, you help maintain the longevity and structural integrity of the concrete, thereby preventing issues such as spalling and premature failure.
