Concrete Basketball court maintenance

Just noticed this around my house. Foundation looks like it was hit by something. I think the grass covered it most of the year. Is this normal wear on my foundation or something serious. I'm on a slab. I live in nj so I think it's the slab with footers. Just wanted to know if I should patch it or call a foundation company.[img]https://cimg5.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/20220902_152022_45826ee067fb30c516038cd989cbccbbe170cd5c.jpg[/img] [img]https://cimg8.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/20220902_152017_b6f2ba4a35663a1496b456d4bf3fbdb74b7d2b93.jpg[/img]

i can get the exact AC unit picture tonight but this is a bedroom AC unit on the house . Im getting new mini splits installed so need to fill in the one hole in my kitchen very quickly because they are installing the outside unit right in front of that wall unit in 2 weeks and i fear there wont be enough room for a pro to get in there after the install. so i want to try a DIY solution. i'm only concerned with finishing off the exterior at this point. the interior will be for another post when i get that AC unit pulled out. its just permastone then cinderblock then the kitchen wall. only thing i can think of myself is build a 2x4 frame and put stucco patch on top of some plywood thats on the 2x4 frame. i know it will be a large 'box' from the outside but i doubt theres any way a pro could even match the permastone and thankfully kitchen faces the rear of the house so really dont have to make it pretty. also its under a window so i dont think i want a window or glass block there . and the house has zero wall insulation so its not like i need to add any lol [img]https://cimg4.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/20220701_123200_b88fa310a011ee10d41eacfeb4dfff71600b630c.jpg[/img]
