Do I need to install drain tiles under my turf & foamon concrete?

[Abrewer]

I’m working on a project for a back patio hitting area. My plan is to cover a 10’x16’ concrete patio with 1” foam tiles, followed by putting turf. I feel like I’ve paid close attention to the details as I’ve been planning this, but it occurred to me today that when it rains, the water wont have anywhere to go. The area I’m installing this in is pretty much flat and it’s not covered.

The foam tiles I ordered say they can be hosed off.. but I’m wondering if I need to start by putting something like this down. Would these work or should I look at something else? If anyone knows of anything cheaper that would work, I’d greatly appreciate you sharing because I’m ultimately trying to do this in as budget friendly way as possible.

You could use something similar to this if drainage is a concern.
