Water ingress under new (professionally fitted) garage door

No, usually the font lip would be inclined slightly away from the door, so water would drain out rather than in.

 

You can't beat gravity! and water will flow down hill.

 

They don't always need a strip (bar exceptionally strong driving rain). My garage floor wasn't floated. When the rain is very heavy, it will let a few inches of water leak under but I expect that because the floor finish is so rough. Had my floor been smooth and tilted slightly towards the outside, I wouldn't have any water. I did once consider a weather bar, but the door is never opened so the stuff leaning against the door just sits on polythene dust sheets.

 

I would suggest that the vast majority of garage doors fitted across the country don’t rely on a seal to keep water out. They rely on the correct falls to the garage to drive interface so that water runs away from the door.

Think of the tens of millions of up and over, sliding, or hinged garage doors fitted across the country. How many of them of them use a seal to keep water out?

 

Did your up and over door prevent any water ingress?

 

The OP has already suggested there was no ingress problem with the up and over door, before the new door was installed - which I find hard to believe.

 

I was under the impression that garage floors HAD to have a fall to the front?
However a builder may not follow rules, and driveways sometimes fall towards the door.

Certainly my house is slightly on the crest of a bend and the houses behind me are considerably lower down.
This means that my pavement is maybe 4" higher than at the garage slab over 20 feet.

 

In such circumstances, they usually/ always have some means of drainage across the door.

 

I've got one of these doors, and unless you have a slight fall on the concrete away from the garage (as I do), or I assume some kind of threshold installed then you've got no chance...

Obviously it depends on the exposure of the door and the direction the rain comes in, but in general there is no way the rubber seal on the bottom will stop water dribbling through unless it has some help.

 

This is a new double garage, maybe the concrete in the old garage with the up and over sloped away as it should.

 

I find it impossible to believe .

 

Thanks for the comments guys.

New door and new floor (laid level by me as I did not know and better).
