Hey, wondering what the best material is to fill in this crack between a set of precast steps and a house foundation. That expanding foam stuff, or what? Gap is too small for any kind of wood etc. Doesn't need to create a watertight seal or anything, just need to fill the void and prevent my mother from dropping her car keys down there again. Keys pictured for reference.
It was a one in a million shot doc, I swear to god.
