    Questions

    About the rebar grid planner

    Do all slabs need rebar?

    Not all, but many driveways, foundations and heavy slabs use it. The plans and the loads decide.

    Where should the steel sit?

    Usually near the middle of the slab, held up on chairs so it does not lie on the ground.

    Is this the engineering answer?

    No. It is a planning count. Plans and local rules set the size and spacing, and we build to them.
