Hello @calccom21
Thank you for sharing your question about your outdoor brick gap. That brick gap is also known as a weep hole, they allow wind to circulate inside the wall cavity. The moving air removes evaporated water from the cavity to the outside preventing moisture damage. The foam item you are looking at is called an expansion joint filler. However, I suggest using a weep-hole vent cover to prevent vermin from entering your wall cavity. It's important to keep your weep hole open to prevent moisture from getting trapped inside your wall.
If you need further assistance, please let us know.

Hello @calccom21
The purpose of the expansion joint filler is to cover the gap between concrete and brickwork. You'll often see it in houses and sidewalks when two large slabs of concrete are joined together. It prevents water and debris from entering the gap. Should there be any movement between the brick or concrete assembly the foam filler adjusts to the movement.
If your joint filler is still in good condition there is no need to replace them. The only reason it would need replacing is if it has deteriorated or has totally disintegrated. To determine the size you need, I suggest cutting a bit of the filler and comparing its size to the ones available at the store. The size does not need to be big, your goal is to get one that will fit into the depth and width of the gap available.
If you have any other questions we can help with, please let us know.
