In the backyard of a friends house, the concrete is disintegrating a little, on the top. It's in Reno, there has been some snow and below freezing weather in the past month. They've only lived there 2 years, the concrete was fine last year. They don't shovel the snow off this, but I don't think that's needed.

Any idea why the surface of concrete would get damaged?
And what a person could do about it? So it doesn't get worse?

It looks like spalding, cause by salt/calcium minerals that weep from
below. Much of Nevada was once a salt water ocean.

Typo alert - the spelling should be spalling, not spalding.

Lots of info online about cause (varies) & repair if you search for
"spalled concrete".
