ᐅ Garage Height – Which Floor Construction to Use (Height Issue)?

We have a small height issue with our garage.
The garage is planned to be only 2.25 meters (7 ft 5 in) high.
If 6 cm (2.4 inches) of screed is added on top as shown in the plan, the height will be reduced to just 2.19 meters (7 ft 2 in).
I am currently planning the driveway so that at least a 2.125 meter (7 ft) door can be installed.
However, the screed thickness is causing problems with the installation height.

What would you recommend in this situation?
I was thinking about either grinding the concrete slab smooth and sealing it (with a coating, etc.) or installing tiles without screed (with an underlay mat?).
Is something like this feasible?

I wouldn’t leave it untreated either. Oil and other liquids can penetrate, and dirt from shoes and tires will also accumulate. So either tiles or a two-component coating.

What kind of 2K coating did you use? Did you apply it yourself? How satisfied are you with it?

I still have to do that myself and would also like to apply a 2K coating.

Of course... dirt will get in somewhere. Oil shouldn’t be an issue anyway. But since it’s a garage, I’m not too picky about it.

But practically speaking: what do you do in cases of
a) rain: leaving puddles isn’t ideal either
b) snow: do you completely brush off your cars (at least roughly) before parking in the garage? And even if you do, there’s still enough snow in the tire treads to cause puddles everywhere.

As I said, my father had the garage coated, and since then he always places old towels under the tires when parking in bad weather, because otherwise everything floods. That’s definitely not how he imagined it.
And a drain can only be installed with an oil separator, right?

I have a checkerboard-tiled floor with underfloor heating.

I also have a drainage system.

However, it should be considered that especially in a somewhat larger garage, it is difficult to create a slope that ensures all water flows toward the drain. In my opinion, this is not feasible.

As long as it keeps snowing, never. However, I have only experienced puddles to a bothersome extent when I once had a garage with a sealed floor but no windows. Whether I would have preferred a fully soaked screed floor instead is doubtful.

Yes, that’s how it should be done.

A slope in two directions, especially designed like a "funnel," would make me worry about uneven settling.

I don’t have a car parked in the garage, so I have never faced this problem.

I assume that is a joke
