Could you please tell our helpful members a little more about what is happening here and the issue you need to fix? It's likely important to know where the water is coming from and what exactly it is you'd like to resolve; they'll then be able to offer some informed and helpful suggestions.
Landscaper who did this did not include drainage or slope. So water from rain just sits there and collects.
That's unfortunate, @innessa.
There isn't any solution I can think of apart from having the tiling in that area redone with enough of a slope to have the water run off. If there were a specific low spot, adding a drainage grate would likely help remove the water, but this appears like it's spread over several tiles. It's a bit of a pain, but you could keep a floor squeegee nearby and brush the water off after a rain event.
Please let me know if you have any questions.
