Here’s my conundrum: we have a living room that was converted garage. The previous homeowner laid down tile directly over the concrete slab floor. We decided to bust out the tile and lay down hardwood (8 mil poly sheeting over slab, 2 layers 5/8 ply glued and screwed to create floating subfloor, 15#flet over subfloor, hardwoods nailed down on top).
This will increase the interior floor height by 2”. The original entry door sill was placed directly on the concrete slab. There is a concrete patio outside of the door at the same grade as the interior floor.
Needless to say, the inswing door will not be able to open at its current height, and will need to be raised 2”.
I am “planning” on cutting the jamb 2” high, prying off the old aluminum sill, creating a form, and pouring a 2” high concrete sill that spans the entire opening, connecting to the foundation walls on both sides of the jamb and using a bonding agent on the existing concrete. Then place a new aluminum threshold plate on top of the new sill, trim the door shorter to fit the new height.
I want to make this permanent and water tight. I live in the pacific north-wet, so water intrusion is/can be an issue (this is why I don’t want to use pt wood to raise it. It has to be water tight)
My questions are:
1: Does this his sound like a good approach to take?
2: Should I use fast set cement or a grout?
3: Any tips?
Thanks in advance for any help

Change to an outswing door and most of your issues will be solved. Much harder for rain to get in an outswing door.
An outswing door would not be legal with more than 1 1/2" change in elevation.
A 2" change sounds to me like a possible stumble zone in any event. Something about the inherent human movement, a step needs to be either less or more than that I think.
