Sealing garage door / floor experiences?

Hello,

Maybe you can help me.

My garage consists of a concrete floor slab.

It is tiled. At the front side there is a finishing stainless steel strip.

Yesterday I noticed that with rain, a minimal amount of water comes into the garage through the joints. In the edge area, only the joints were really darker, as they were wetter. In the middle there was a small puddle.

The rubber seal of the Hörmann sectional door lies flush, but the joints are slightly deeper than the tile.

I would like to have the garage sealed tightly.

I have the following ideas, maybe one of them is good?

One could glue or screw an L profile (stair profile) or a transition profile onto the tiles or the edge. These are usually 1-2 mm thick. The door would sit more firmly but would certainly still close completely. Water could no longer run underneath.

Option 2 is a rubber seal, for example available on Amazon. The flattest variant I found is still 12 mm high. Here I am afraid that the door would no longer close completely because the contact point is now significantly higher.

What do you think?

During heavy rain, some water also comes in here (mostly at the sides, as there are a few open spots), but normally there is a slope that inclines towards the gate and thus drains quickly. Do you not have a slope in the garage? Additionally, the paving right next to the garage is also laid with a slope.

So, nothing comes in on the side for me. Only from below. No, there is no slope... the pavement is still being laid. As I wrote above, it's about the issue of water under the rubber seal / joint.

I would stick on a so-called drip edge profile, with the high point behind the rubber seal of the gate. So if you compare it to garden shears, not anvil but bypass.
