Good afternoon everyone. I'll start by saying that I'm an HVAC tradesman, not concrete. However, I figured I could get punted in the correct direction here, and get advice on if I need to have this addressed right away.
I just bought a house about two months ago, and recently noticed the concrete on the edge of my slab starting to flake, along with my block wall. I could be wrong, but am nearly 100% sure this wasn't like this, or at least as noticeable 2 months ago. I live in Henderson Nevada, where it's dry as a bone. Hardly any rain. I had a pest control spray applied around the perimeter of my house and wall a month ago or so, and that's about all that's been done. I don't remember it being like this before that. Even those red rocks around the area were softened and turning to dust. Any idea what may be happening and what I need to have done to stop this?
