I have googled this, but to no avail, and was hoping someone here would know
the answer. My garage floor is a concrete slab, the walls are cinder block.
There is a slight gap where the walls meets the concrete (perhaps 1/8 of an
inch). I am not sure whether this was ever filled or whether I'm only just
noticing the gap, but I would like to fill it in. Would I use a kind of
silicone, mortar, or perhaps even grout to do this? I'm just not sure which
material would last but still allow for expansion. Or should I leave the gap
I live in Florida. Moisture is not an issue, but bugs are.
Any help would be appreciated. Thanks!
