Ever drive over a manhole that was not flush with the pavement? This is how they fix them.
Via Mr. Manhole:
In 2002, we recognized that there had to be a better way to remove manhole frames from the road, and came up with the Mr. Manhole system, a state-of-the-art set of tools, and a repair method that makes manhole removal and repair easier and safer for your crew.
It looked like it was starting to snow a bit at one point. Let's hope Mr. Manhole has the number for Mr. Plow.
