Not really sure how to properly explain this, but here is the situation. I have a door that goes from the garage to the backyard, and I need to raise the height of the concrete sill. Presently, the sill (footstep?) is level with the interlock outside. This causes serious water infiltration into the garage in the spring. I have attached a picture that, I hope, will greatly help in explaining what I intend to do.
In the picture, I need to raise the level higher a few inches, which includes the areas marked at "Addition" and "current 2"x4". The door frame is partly into the 3 feet foundation of the garage and the wooden upper section of the garage wall.
I am looking for suggestions and ideas on how best to raised the concrete part.
Any ideas and suggestions will be most welcome!
Regards and thanks in advance,

not a big deal, serge,,, get the 2x4 outta the way, form, & pour w/polymer-modified repair mortar extended w/CLEAN 3/8" stone,,, couple pieces of steel wouldn't hurt,,, & remember your basic conc principles - CLEAN & surface-saturated dry.
Now that I have somebody's attention, I have some additional questions.
I have worked with mortar last year when I installed marble stones in my main entrance, but I have never worked with concrete before. So, here goes:
I search on Google returned numerous hits concerning polymer-modified repair mortar. Which one to choose? Suggestions?
What is meant by "extended with 3/8" stone"? Does it mean to add 3/8" crushed stone to the mix? If so, how much?
How about the pieces of steel? What is the suggested idea here? Drill in the existing foundation and insert some "reebars"(sp?)? If so, how many and where?
for your/this purpose, conc's the same as mortar but w/bigger rocks,,, yes, add per stone,,, 60# bag you can add 30# - extended does mean to add which increases mtl volume w/o sacrificing strengths.
many good mtls in the mktplace however none i would buy from an apron store,,, ck w/const supply house.
i'd probably drill & 3 vertical pcs of #4 steel & wire a horizontal piece at their vertical mid-point for addl flexural strength.
'surface-saturated dry' is no standing wtr BUT the conc surface won't accept more wtr,,, purpose is to prevent existing conc from sucking out the wtr needed to cure/hydrate new mtl.
don't worry about being ignorant,,, i am OFTEN, still
Thank you, sir, for the answer and suggestions. I expect to get at this project in the next few weeks. I will try to post before/after pictures when the deed is done.
Cheers!
