This Is How Workers Fix Cracked Or Uneven Concrete With Foam

Cracked concrete can be dangerous for pedestrians, which is why cities need to maintain it well. Have you ever wondered how construction workers fix those cracked or uneven concrete slabs? It”s not with magic (like I always thought). They actually use foam to do it.

You wouldn”t think it, but foam can actually fill in concrete gaps and create a stable foundation. Not only that, but it”s also hypnotizing to watch.

Never knew I could get so psyched about concrete, but that music did it!
