What will stop water from coming in under a garage door with a rubber seal on the bottom of garage door?

Question

I am trying to avoid putting a trench in concrete drive with a drain cap and running it to the lower part of my property.

Answer 1

Can you add a threshold?  You should be able to make a "mini speed bump" out of concrete, that would hold the water back.

Answer 2

We use a product called StormShield that is an actual garage door threshold.  It doesn't require all the drilling as mentioned above.  It actually comes with a structural adhesive that adheres the pvc to the concrete.  We always tell customers up front, however, that if it's a seepage type issue (even a fairly large one) it should work fine but if the water is coming in with any sort of force and/or depth you're probably going to have to install a drainage channel.  It's simple to install and not very expensive at all.

Answer 3

Is there a slanted driveway above the garage door?

Then it would be difficult to avoid water running into the garage.

However you could try sandbagging at the bottom interior of the garage door.

Good Luck

Answer 4

You need a garage door threshold. This is a rigid pc. of rubber that you fasten down into the concrete floor right under where your door shuts. It is a great idea.

Simply shut your garage door and mark exactly where the bottom door seal hits the concrete.

Now you use tapcons (concrete screws) to fasten down the threshold you just bought. Also need a hammer drill,felt tip marking pen,tape measure, #2 phillips bit insert for drill, # 2 x 1-1/2" Phillips tip for drill.

Installation instructions should come with threshold kit.

Note: You will have to adjust your overhead door to stop on top of the threshold, as your floor is more or less higher than it was, which will cause garage door to hit the threshold and then reverse and go back up. This is a simple adjustment to your door opener. You will need to adjust your top rollers on the garage door also to allow door to still fit back against the top weather strip when closed.

For added protection use good 100% silicone to seal under the threshold before you put it down on concrete.

Good Luck

Answer 5

I would do just what you said.  Gravity will always run down hill.  You need away for the water to drain away from your house.  On something like that, I would fix it right to avoid a major water damage problem down the road.
