Filling a hole in granite steps

[mrjohneel]

A railing guy drilled a wrong hole in a two-inch thick granite step leading to my front door. The hole is about 1" wide. What's the best way to fill that hole? A concrete mix? Some sort of caulking? A specialty product? It'll be under a railing in an unobtrusive spot so the look is not as important as making sure it's filled so it doesn't fill with water/ice and crack, etc. Any help will be appreciated. (And, no, I don't trust the knucklehead railing guy to fix it correctly.)
Thanks!

IMHO, a pigmented epoxy based product.

Was the hole drilled using a core bit ? If so was the core salvaged ? Perhaps you could glue/ cement the plug back into place ?

Yep. Mix some granite dust in it to blend in.

i wish I had a standard product but when I used to build strip kayaks I found out that most epoxy products are basically resins, fillers and pigment. I think any shop that does kitchen counters probably might be source of premix.
