Preventing Rain From Blowing Under A Garage Door
I am posting this for a friend....he has a large shop with several
large roll up doors. When it rains heavily and the wind is blowing into the doors, water will enter the shop under the rubber door seal...lots of water. Any suggestions as to how to prevent the water from entering? Thanks TMT |

There are various brands of garage door threshold that might help. Google "Garage door seal" and you'll find hits on several brands and a variety of suppliers. -- -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |

Thanks TMT Woodworkers Supply used to have a threshold you could buy. Seems like it was about $75 for a single bay door size. Included a rubber threshold and a tube of silicone seal. I still have an unopened one sitting in my shop, it's about 8 years old though. Didn't need it after I installed the french doors where the roll-up door used to be. -- If you're going to be dumb, you better be tough |

A good rubber seal for the bottom of the door. And a trench drain right in front of the door (within 6" if you can) with the concrete under the door sloped towards it. So all that wind- blown water falls in the trench drain and drains away before the door seal has to deal with it. If you plan on moving heavy gear in and out of the door, they make trench drains with cast iron or cast steel grates that can take it. We need to dig in a gravity drain for our front yard, and it has to go right in front of the garage door. I plan to slow down and make it a trench drain as it goes across the opening. Then all I have to do is rent a concrete profile grinder to retroactively put the drain slope on the lip of the garage slab past the door resting location... -- Bruce -- |

Preventing Rain From Blowing Under A Garage Door
Rain, even wind-driven rain, does not have enough pressure to force its
way in, in quantity. There has to be gaps in the seal, or insufficient pressure. Gaps would be caused by uneven concrete. Some uneven-ness is expected & is taken up by the flexibility of the seal. First thing to try is to increase the pressure on the seal by reducing the lifting spring tension. If that doesn't work, because the floor is too uneven, a different seal might work. A flap on the outside would likely be better than a compression seal under the door. If not, the floor needs to be leveled. Except that is not very practical, so a threshold needs to be installed. The problem with that would be moving heavy machinery over it. Bob |

Thanks TMT I've seen a small "bump" on the floor right up against the inside of the door (on the floor) it seems to do the trick. The one I saw was part of the concrete floor but would think a well cemented down one made of some priable material (rubber like) would do the same thing. ...lew... |

How the grading outside the doors? Mark One thing you could try is putting a drain in on the other side of the garage door. It would be a trough drain, starting at one end of the door and ending at the other. Water would then be encouraged to run in to it and out of the building somehow. It doesn't prevent the water from getting IN the garage doors, but it does prevent the water from doing much damage. I've never tried it, I only thought of it as a solution to the same problem. The garage builders sloped the outside of the garage incorrectly so just about every rain brought flooding. Puckdropper -- Wise is the man who attempts to answer his question before asking it.

If one looks around...one can find rolls of computer room "wire covers" that used to be laid on the floor with double stick carpet tape and wires laid in it so yall could walk over it and not trip. Ive used it to seal garage doors, quite nicely. Gunner |

Thanks TMT The water is following the airflow. There's a higher pressure outside the building than inside, so when the wind blows, you have pressure gradients. My wife and I were in a hotel in Dallas a few years ago, and the horizontal rain (driven by wind, of course) put a high pressure area on the windward side of the hotel, filling several rooms on that side of the hotel with up to an inch of water. We had to move to another room. My point is that you can seal it with every gadget known to man, and it will still leak, or you can try and find a way to equalize the air pressure difference in a passive way, such as vents or wall louvers. |
