Raising rough opening for the door

Hello

I saw another thread about shaving off the rough opening, but i want to do the opposite - i want to raise it about 2 inches because right now it is leveled with the ground and rain water pretty much has unobstructed entry into the basement. There used to be 2x8 in that spot that got all rotted away and it wasn't providing 100% water seal on the sides either.

I want to put a new standard size exterior door there and there is no way i can regrade that spot.

My question is - what sort of concrete mix (there are so many) shall i use for application that is 2 inches thick and that will be on top of existing poured foundation wall. And am i thinking in right direction?

Thank you!

I don't know of a cement product that will bond and hold together being that thin. I would consider doing similar to what was there originally. You can replace the 2x8 with a new piece of 2x8 that is treated for ground contact. You can use another material such as vinyl or some other composite material that can't absorb water or rot.
