This is insane. We need a pro to explain what kind of concrete this is because they're pouring it so thick, the guy looks like he’s sinking while trying to level it. Watch how carefully he works—yet the mix is surprisingly easy to manage. If you look closely, the concrete seems super airy, but it fills every corner and even lifts the entire floor with no trouble.
Ever seen anything like this before?
