Concrete Slab Damage - Inside Sliding Glass Doors

10 year old home in FL - I'm replacing the carpet in my bedroom and did the tear out this morning only to find damage to the concrete slab that's against the threshold to our sliding glass door. The concrete against the door and approx 3 inches into the room along the door is soft, a little wet and the carpet tack strip nails have disintegrated over time. Tack strips came up with the carpet.

I have a door guy coming tomorrow to address the leak (assuming it's coming from the door) but what do I do about the concrete??

Remove as much as possible then fill it back in??

Yes, just chip away any lose or damaged areas, and get a good quality concrete patch like top & Bond. Be sure to follow all directions on the package. Preparation is everything.

Got a picture.
Just a guess as to what caused it because of a builders 101 mistake.
That threshold is even with an outside deck, patio, stoop.
There should have been a minimum of a 2" drop.
Having it even is a sure way to have water get in under it and cause damage.
Google "jam sill".
Home depot now carry's them.
99% of the doors I've removed where never flashed correctly.
Your lucky it's just a slab, I've seen thousands of dollars in damage done cause from a lack of A $20.00 item and 10 min. work.
