Any of the two-part epoxy puttys that you can get at the hardware store should be strong enough to patch that. JB Weld makes a line of putty that you can pinch off pieces of and use to patch that hole. Dap brand "Plastic Wood" would probably work as well and it's sandable. You should be able to sand the epoxy putty as well (i think), I just haven't used it in an area where i needed to sand it.

Another thought is a concrete patch. You could go to the concrete section of your hardware store and stare at the products there (that's what I do, LOL) and see if inspiration strikes. Sakrete makes a pre-mixed concrete patch that I recently used to fill some holes in my pool decking. It comes in a small bucket and was really easy to mix and use. That one is meant to fill 1/8 to 1" gaps. Sakrete makes another one called "Top N Bond" that is meant for 1/2 inch down to a "feather edge" which I have not tried yet. It might be the right texture to match your job.

I would probably go for the plastic wood or the concrete patch just because of the consistency. Those two products might be easiest to work into the spots you need to fill. Of course for the concrete patch you can mix to any consistency you like, however the thinner your mix it, the weaker it becomes when cured.
