Newbie, with questions

[71Vette]

Hi from Northern California, I've been lurking around for a while and can't find what is causing my garage floor to spall like this.



The floor is 30 years old and the epoxy ( Home Depot ) is 1 year old. The top 1/8" or so of concrete is popping loose. It is on the floor and the stem walls around the inside and outside of the house. Does anybody have a clue what is happening to it? If it matters I live within 50 feet of the Sacramento delta.

Thanks for your help,
Rob

Welcome from Ohio. You should probably post this in the Flooring Section. Good luck.
