Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pick the 2 in. position for slabs on grade and the 2.5 in. position where a bit more cover is needed. Space chairs at consistent intervals so the rebar stays at the correct cover height during the pour, and walk the grid carefully or use additional chairs in traffic areas. Always check local building codes before starting your project.
Always check local building codes before starting your concrete project; chairs must remain in place during the pour to maintain proper bar cover.
Order the PROWORX plastic rebar-mesh chairs, 50-pack, to keep your rebar and mesh at the right height on the next pour.
