Garage Apron Height

[climb.on]

I have an apron that is 50' long on one end a 12' wide overhead door. On the other end a 3' man door. Slab on grade, no course of blocks. I think I would like to have the apron set 2" lower than the level of the slab and build up to the the slab at the overhead door. It just seems I'm asking for future water trouble having that much apron at the same level of the interior slab. My concrete guy thinks it will be fine having it up, but he is fine doing it my way too. I see lots of example with the concrete right up tight to the bottom of the man door when it's right next to the garage door. Mine is about 20' away.

So keep the apron level with the slab and doors all the way across, or drop it all 2" and build up the apron at the overhead door? Thoughts?

Here's the best pic I can find at the moment of the front of the shop.

Ayuh,.... As long as the apron pitches Away from the garage, it won't matter,.....

That it will. Just will pitch more right at the overhead door.

In our area, the common practice seems to be to form the apron so the garage door sits down into an approx 3/4" lowered level in the apron so wind driven rain and snow can't get into the main garage floor. The apron is sloped up to the place where the man door is so the apron at that point is even with the garage slab. A sealed threshold at the man door prevents any rain or snow from entering.

Lowering the apron 2" at the overhead door seems unnecessarily excessive and will be a pain to roll tools and equipment into the garage.

Apron would be 2" lower than the slab, all the way across, except at the overhead door, where I would build it up to be level with the garage floor.

I sweat the details a lot, but I decided to leave it level with both doors all the way across. It might look funny built up like that and I think it will be just fine as long as it has the proper slope and I'll have a gutter across the front, to minimize water intrusion issues.

That is how mine is done, no leaks at all.

I don't like any lip at the door because it makes rolling things in and out very difficult.

But then the driven rain becomes a problem. A really good pressure sealing system can mitigate most of that.

Slopes, both inside and out can also help. The inside one should not extend too far and neither one should be too steep, as that becomes a problem.

A good roof overhang and gutters can also be aids.

it doesn't have to be a step at the garage door, that transition can be a ramp up, (approximately 1/2" over 2"-3") and it'll keep the water out and enable you to still roll a loaded tool chest in/out..
