You have sidewalks?

Seriously, why would you need/want to replace them? They're spacers put
in place when the concrete was poured. No functional value once it
dries, near as I know. But I'm no builder, so YMMV.

perhaps not entirely a garden question, but it is near my garden. i have wood
barriers between slabs of sidewalk concrete, not the fiber boards, but actual
wood. i have some that are rotting away from the elements and bugs. what are
those pieces of wood call, or better, what do i look/ask for at home depot?

thanks for any help
