Drove past a parking garage in Atlanta yesterday and noticed the concrete ramps had these weird wavy lines all through them
I was just sitting in traffic on 85 and looked over at this 6 story parking deck near the Mercedes Benz stadium. The ramps going up and down had these repeating wavy ridges running across the surface. Not like broom finish texture, more like somebody dragged something heavy and uneven across wet concrete every few feet. Made me wonder if that was some kind of pour issue or maybe an intentional design thing for drainage or traction. Has anyone else seen this pattern on parking garage ramps and know what causes it?

Yeah the ones near the Braves stadium have the same thing. I think @the_christopher mentioned screeding but I bet its actually from the bull float they use to smooth the concrete on a slope. The weight of the float plus the angle makes it drag unevenly and creates those waves. Its like trying to paint a ceiling vs a wall, gravity messes with everything. Probably not a big deal structurally but looks kinda janky up close. Still better than those garages with the peeling epoxy coating that looks like a shedding snake.

Notice how once you start looking for little weird details like that you see them everywhere, it's like the world is full of these small oddities that nobody ever talks about. That wavy pattern is probably just from how they screeded the concrete on the slope, same as how you get those lines on sidewalks but way more obvious on a ramp because of the angle and weight of the equipment. It's funny how the stuff we drive on every day has all these hidden secrets to how it was built, and we never think about it until we're sitting in traffic staring at a wall.
