Concrete foundation beveled at doorways?

[Vintage Veloce]

So, I am planning to have a level and flat garage floor.
Is it possible to have the doorways beveled? So that rain hitting the roll-up car door and running down to the foundation flows out and away away from it?
(I guess on the man door you take care of that with the sill plate.)

How do they form that? Or does that make the doorways a second pour?

You can recess the floor at the roll up door locations so that the bottom of door sets in this recess. This will help keep rain and wind blown rain from coming under door.the recess can also be sloped slightly outward. About 3/4" deep or so should be fine. You can also bevel or do. 3/4" radious edger to help soften the height.

when forming they would drop the section at the roll up door and trowel it accordingly

A common thing.
Just be sure the slope continues away from the door in the driveway.

I have done it both way's (recess like above & just a bevel)
cbacres above method is the best way imo. Even with a leaky seal, water will not come in.

You will need this recess to be 3" or so INSIDE of the framing and about 3" on either side of the door r/o to allow for the track & door to sit in this recess.

I'd have to measure mine, they are either 3/4" or 1", I can't remember. The form board was attached lower than the floor level. Once it was poured, the concrete was just worked where it needed to be.

Or slope the entire floor.
I did and it is nice for hosing out and snow melt off cars.

Bad thing is leveling all the equipment.

A slight 3/8" slope at each of my roll-up door openings was a simple matter of just telling the job foreman what I wanted and they put it in by hand troweling it. No problem and they said they do it all the time, no big deal.

One method -

What I did was run a 5" piece of EPS where the doors are located and 6" everywhere else around the perimeter. On top of the 5" pieces I attatched a removable 1" piec of EPS. I had the concrete contractor finish the floor to this level. After the slab set up, I removed the 1" piece which left a nice pocket for the door to settle into. The apron will be finished from this level.

Great info! Thanks guys.

Personally I would bevel it and that's what I did at my last garage. Easier to roll jacks etc in and out. The weather lip detail (vertical step with depressed pan area) makes it more difficult to roll things in and out.

Bevel - contractor has a gauge that rides along the door opening form. Put in when troweling starts. Drops edge about 1/2in and extends about a foot to the inside. Even with the door cracked open, water will not come inside. Simpler and more functional than dropped area.

I completely forgot doing that way, that is the one way I'll do mine in the future.

I can't quite picture this... could I ask you for a bit more detail? Maybe a picture of this cool gauge?

Nothing much to it - take a foot long piece of 1x, put a nail or screw in it about 1/2 from the edge (whatever you want your drop to be).

Now, after the cement is floated and flat (can be troweled too)and ready to finish- take the gauge and pull it with the nail riding on the edge of the form, and the other end just kissing the surface and use it to remove the 1/2in by foot or so triangle along the door opening. Then use your steel trowel to finish.

Hmm. So the form is flat and level, and you push the 1x into the concrete to the depth of the nail? While the other end of the 1x comes up to the surface?

... gotta talk to my concrete GC about this.

no metal building yet, but they took the plans and hand troweled where the roll up doors were going to be. I didn't ask, they just did it.

exactly, just scrape off the excess and trowel finish it.

 

[jgorm]

Mine are beveled. They just eyeballed it when they finished the concrete. You can see the slope by the conduit.

Thanks Radix2!
