Water/rain under garage door

[stangman39]

One side of my shop (the older side) has a single garage door which I open and close manually. It has always had a water/rain intrusion issue when we get a lot of heavy rain. Two years ago I replaced the bottom of the door seal and it didn't help much.
I'm pretty sure the concrete under and on the outside side of the garage is flat or has a small slope inward towards the door so the water isn't flowing away from the bottom of the door.
I've thought about putting down one of the "tsunami" weather strips under the door and sealing if good...but am wondering if a better solution is to have someone (or maybe I can do it myself by renting a grinder) grind a slope into the concrete so it's angled away from the door.

Thoughts/comments?

Thanks

Either one would probably work. A ten food threshold seal is not that expensive and less work.

I have a similar problem and am thinking about putting the seal down. Just not sure how it will work when sweeping or hosing out the garage.

It looks like the grinding disc that can attach to a grinder is about $45 at Home Depot.
Never used one before so not sure how much work it would take to grind down 10ft by 5”
Not a concern for me hosing out the garage or sweeping
Just want to stop the water from coming in
Also thought of adding an awning above the door but that’s probably the most costly route

I'd love to be able to check out that product but the picture is so low-res, I can't even make out what it is! Maybe someone could get a better picture online? Thanks!

Not attempting to speak for armor poxy here but I imagine it’s very similar to Tsunami Seal mentioned earlier in thread https://www.homedepot.com/p/Tsunami...PIPHorizontal2_rr-_-202199771-_-202199784-_-N
In any case here is a profile picture to give an idea of this type of product (this one is tsunami seal)

I would try grinding the concrete first. Mine has a very slight slope to it and I have never had a water issue even in driving rains.

Nothing against the threshold products but personally I cant imaging having something like that to drive over every time I pull in and out of the garage, not to mention trying to sweep the garage floor out. It would drive me crazy.

I have a Tsunami seal sitting in a box and I can’t make myself install it because it will make rolling stuff in and out with small casters a *****, like my Weber grill.

You could rent a larger grinder with a cup wheel and grind that away in no time.

I’ve been thinking about getting one of these for a while. Is there something about yours that would compel me to spend 50% more than the one from Home Depot?

My Home Depot has tool rental. I know they have concrete grinding rentals. Is this what you would suggest renting? Not sure if I can set those at an angle to create the slight slope needed.
