When positioning reinforcing steel in a concrete wall, what is used to maintain its position?

To maintain the position of reinforcing steel in a concrete wall during the pouring of concrete, wire ties are commonly used. Wire ties secure the rebar in place by binding it together and attaching it to forms or other reinforcing elements. This ensures that the steel remains in the correct orientation and location throughout the placement of the concrete, helping to maintain the structural integrity and design of the wall once it has cured.

Concrete spacers, while they can help maintain a certain distance between the rebar and the concrete to ensure proper cover and bonding, are not primarily utilized to secure the rebar in position during the setup phase. Rebar chairs serve a similar function, helping to elevate rebar off the ground, but they do not effectively secure rebar in multiple dimensions. Stakes are typically used for securing forms or bracing rather than directly positioning reinforcing steel. Therefore, wire ties provide the best solution for maintaining the accurate placement of rebar in concrete forms.
