Which option is used to maintain the position of reinforcing steel in a concrete wall?

• A. Wall
• B. Form Wire
• C. Metal Plates
• D. Wire Ties

Answer: (D)

Keeping the reinforcement in its planned position during a concrete pour relies on tying the bars together with wire ties. These ties loop around intersecting bars and are twisted tight to lock the grid in place, preserving the correct spacing and cover so the concrete can encase the steel without the bars shifting. In a wall, you’d layout the rebar grid, use spacers or chairs to hold the bars at the right height, and then secure every crossing with wire ties. Other options don’t serve this purpose: forming wire is mainly for securing formwork, metal plates aren’t the standard method for holding a rebar lattice in place inside a wall, and the wall itself is the structure, not a tool for positioning the steel.
