I'd like to build a deck outside my back door, however the concrete slab/pad that's there currently has been damaged over the years and the drainage doesn't work.
The main issue is the channel that's there has sunk in the middle so water ends up sitting there.
I don't really wanna remove it all as it's quite thick and that would be one hell of a job.
Wonder what the best way to resolve this issue is, thinking maybe if I dig up just the drain channel and then redo that part? What's the best way to lay concrete so that it slopes towards the drain?

PS: I will make an access hatch in the decking for the drain cover.
