this is probably my favorite tiktok of all time and I finally got around to showing it to my dad the other day and now he comes home every day and tells me about all the places he saw crumbling concrete and says "guess they didn't add enough chinchilla flakes"
My dad has worked in construction is whole life, primarily with a company that does concrete foundations, and I immediately sent him this back when I first found it on TikTok, and he IMMEDIATELY shared it with everyone he worked with. They apparently still quote it on his job sites to this day.
