Deteriorating AC & Well System Concrete Slab/Foundation

[Emmanuel Sanchez]

Hello BiggerPockets fam,

Curious to gain some insight on an issue that was brought to my attention at my rental property. 

Tenant reached out, sharing that her landscaper pointed out that the concrete slab/foundation where the well water system and AC units sit are "deteriorating." Please see images below. My apologies if they are slightly blurry... they came directly from the tenant.

Any recommendations on how to fix this, or a specific vendor type that I should contact? The property has a 10-year structural warranty... perhaps that may be avenue I should pursue?

The property was built and completed in 2022. I assume that since it is new construction, over time the ground settles and could probably be the root cause of this. 

Any other investors in the Cape with new construction have experienced this?

Many thanks,

Emmanuel

From what I can tell, the ground under the slab has just sifted a bit. If it were me, I'd get some dirt or gravel and shove it under the slab just to give it more support. Obviously, the slab is still holding everything it needs, so the dirt would just be to keep it that way. I would look around to see if something similar has happened around the rest of the house just in case, but otherwise, it doesn't seem like a huge issue. Check connections, make sure everything is still attached correctly, but it should be a very, very cheap fix.
