Garage Door Threshold Seal

[jcs_in_ky]

One of the roll up doors on my shop gets water coming under it every time it rains and the wind blows. My slab extends about 6" past the outside of the door, water collects on it and comes under. I've been thinking about trying some sort of threshold material to hopefully help the door seal a little better and act as a dam to keep the water from coming under. Has anyone tried this product? http://garageaccessoriesrus.com/doorseal.html

Do you have a rubber seal on the bottom of the door now?
If you do, and it still dosn't seal all the way across then either the door is not coming down square or the slab is tilted.
I have put wedges on the bottom of doors that allow for as much as 1 and a half inch of tilt in the slab across a 10 foot door width.
When it is down, the bottom of the door should be with in 1/4 inch of the slab.
All the way across.
Then the normal bottom of the door seal will work fine

I took a quick look at my slab tonight. Tomorrow I need to check it with a level and straight edge but it appears that the main problem is that the slab is low in the middle so it creates a dip in the slab between the sides and the center. I might be able to make some kind of shim to fix it.

I do have a rubber seal.

In the situation you described above what you did if I'm understanding it correctly is to make a wedge to fit between the door and the seal so that the seal would like up correctly with the slab?

You may also want to check with a garage door company that sells and installs doors (not the box stores). They sell different types of seals for varying applications. A friend of mine had the same problem. He called a company up and got a different seal that was basically a hollow rubber tube, but considerably larger than the standard seal. With it being larger, it would conform to the floor better. He never had a problem after that. You could also saw cut a few lines across the floor underneath the door seal area, so the water does not have a smooth path to follow.

If the pitch of your driveway is causing the rainwater to run into the garage, I suggest a trench drain be installing to get that water away from the garage doors.

Although I have never tried this, it was told to be by a garage door mechanic. For problem floors with a dip in it, he said they take a length of old garden hose (fittings cut off), and put it in the interior of the seal for the full length of the seal. The hose makes sure that the seal is "puffed out" and gives it some resistance to crushing. This lets it mash flat in the good slab areas while protruding into the dipped areas on the slab and helping to seal those areas. He said that sometimes you need to readjust the door after insertion of the hose.

I was looking at it last night and was thinking if I could find a thicker seal that would compress more that might help. Unfortunately there don't seem to be any good garage door companies in this area. I've been waiting over a year now for one that was supposed to come out to look at a door on another building we have. Maybe I can find a source online where I can order a different seal.

I have the same problem due to an uneven slab. I installed a product similar to the one in the link, it didn't help a bit, just made it more difficult for me to sweep out the water. I may try the garden hose trick or a bigger weatherstripping piece as well. I thought about trying to level the slab but I'm betting I'll end up with a bunch of small puddles instead of one big puddle.

They do make adjustable retainers that will alow you to lower or raise certain spots of the rubber to fit an uneven floor. Like this here on the top of page 11. Or if it is a wood door you can scribe the bottom and cut it to fit the floor.

Nova65ss, Do you work with garage doors? My door is a Janus Intl. I can't remember the model number, I'll have to take a look at it. I tried to talk to them about this door and they weren't very helpful. They want me to talk to the company I bought it from but I bought it from Kentucky Steel Truss along with one of their buildings and they were no help at all. I wonder if most brands of doors use the same seal or if they are specific to the manufacturer. This door was installed about 2 1/2 years ago. Initially I had some problems with some minor leaking around the seal. I raised the door up when it was really warm and worked the seal out some, after that if it leaked it probably wasn't more than a few ounces of water coming under, even in a bad storm. I hardly ever used the door, I think I only opened it a dozen times over the last couple of years. Then I installed a lift in that bay and now it's going up and down a time or two a day and the leaks have come back only much much worse.

I have dealt with these people for a number of years. http://www.spfldoverheaddoors.com/default.htm It doesn't cost anything to frop them an e-mail and ask what they would do or what type of seal they would recommend. They may have pictures or may possibly send a sample. One thing I did notice on their site, they have tips on painting doors, tuning up doors, and they have a section where you can design your door, from standard to wood carriage doors. That may be handy for someone building the new shop.

If you have a dip in the center of the slab my idea for a wedge will not work.
I did that for a slab where the whole thing tilted.
I am thinking about finding something to fit to the bottom edge of the door where the low spot is.
Between the door and the current seal to push it down a bit.
Mabe a length of pipe insulation?

If there is a "dip" somewhere in the sealing surface of the floor, why not use some type of epoxy leveling compound to make it smooth and flat?
