thin added cement for garage entry ramp

I have a double garage with uneven cement floor, and uneven line for the garage door to sit on.

I want to, around the garage door landing, add concrete to fill in 2-4 in of height, so it will be flat to meet with the garage door, and will give me a 2 in high lip so water can't run into the garage.

i first want to avoid cutting out the patch of cement and repour and reshape.

My thought:

1. what kind of material I can use to add 0-4 inches to the old cement floor, and endure the abuse of garage traffic everyday? the finish edges also need to be nice ....

2. or , manufactured ramp to serve as the ramp? I still need to add some height to the floor, the added cement can be imperfect so the store bought ramp can cover the imperfection?

Concrete does not like to bond to concrete, especially old dirty concrete.

You can use bonding agents but being outside in the weather with cars pulling in and out I doubt it's going to last long.

You dont have a location but if you have freeze thaw conditions it will only get worse sooner!

Fast and dirty repair...I would chisel out to a depth of 6" and a width of about 3" to 4". Fill with 2" of crushed stone. Try to compact it as much as possible then fill with concrete. It'll last about 3 to 4 years before it breaks up.
