Located between patio slabs at a house in Southern California. Am looking to possibly replace it during the cosmetic repairs planned for the area. Even if I don’t replace it, am wondering what this stuff is called and what it’s supposed to do.

Oh, yeah I’d be willing to bet the irrigation is the primary culprit here. When you go to fix this, you should consider addressing the drainage path of your irrigation. Otherwise, the soil may continue to shift underneath the new slab and cause the same issue in a few years.
