What is this concrete crack filler and more?


I notice these mostly on concrete stairs, walkways, and paths to fill gaps between concrete "blocks".

It looks like concrete gap filler that I use for some homeowner housework, but it's a lot wider (and perhaps deeper) in area than what I do with it.

Is this concrete gap filler material or something similar? And they don't actually fill it deep with that right? So then what is likely underneath that?

IF you'll look, you'll also see it on conc hgwys, airport aprons, & any place you'd find conc slabs,,, its joint seal & the purpose is to keep incompressibles OUT of the space between the slabs,,, why you ask ? when conc ( or any solid ) gets hot, it expands [ hi-skoul fizzix ] when it expands, the ' gap ' gets smallered,,, when it smallers, the stuff that won't compress causes the conc to ' spall ' ( fracture [ break ] )

joint sealants are designed for optimal performance at certain depth:width ratios,,, to seal the jnt w/more would cause either adhesive, cohesive sealant failures OR, at the least, shorter svce life.

underneath the sealant you'll usually find a foam-stuff backer rod installed @ a depth to prevent oversealing,,, simple, huh ?
