My brother bought a 30x40 kit thru them, that he and I erected a couple yrs ago. The kit was complete and everything was high quality and straight.

TTT....

Brian,

Did you use any kind of threshold under your garage doors with the gravel floor?

I am currently working on a 65 x 65 and will have gravel floors for a while while I spend money on insulation, etc. Just wondering how well it sealed up with garage doors on a gravel floor.

I've got 4-6" of concrete in there now.

As for when I had the doors set with the gravel floor, I laid out a 2x12 and a 2x6 on top, to simulate the thickness of the eventual concrete floor. I sealed up the corners of the doors with spray foam for a few seasons to keep mice and snakes out. That coupled with a couple of ultrasonic pest deterents, I didn't have any issues. I had 10mil poly (very thick) on top of the crush'n'run for those seasons as well. I definately had moisture wicking through the gravel. The back of the poly was always wet, but did not smell, mold, or cause any issues. I installed a few industrial ceiling fans that ran full blast for those seasons.

I'll attach a few pics of the concrete going down that I have handy. I have better camera pics somewhere.

If you look closely, the garage doors sit down into a 'little tray' that is the same height as the apron, about 1" lower than the garage floor. The apron slopes away from the barn on 3 different axis. This keeps rain water from coming in under the doors, and it works PERFECTLY. I spent a fortune building up the land as this was almost swamp land before I built. I didn't get 1 drop of water in the barn from Hurricane Irene and TS Lee 10 days later. The tray is formed by a piece of shaped angle-iron set into the concrete at the pour. The angle iron ensures I won't have any chipping there at the entrance. My good friend Tom, OSO member Bajario52, put all this together for me, and I am very thankful for a perfect job. We also put in many floor cuts to prevent cracking--not one crack either! It was 36 yards of 3500 lbs. psi concrete, with fibers; and steel mesh around all of the poles.

Great info, thanks :drink:

I was thinking of laying down 10 mil poly under the gravel to serve as a moisture barrier. I like the ceiling fan idea too. Your shop turned out great!

I had 10 mil under the whole gravel pad before they started, with about 4" of gravel over the top. By the time construction was done, after the auger bits, etc. etc., that poly didn't do much for moisture barrier.

I had to buy 10mil poly again, and lay it over the top of the gravel, and that was my top surface; with a couple of wheelbarrow loads of gravel spread out wide just to hold the poly down. I would recommend this for your application as well, especially since you will be insulating. The poly was actually not too bad of a floor to do work on either. It's much easier to find a dropped nut/bolt/whatever on poly vs. gravel. I think it cost me $150 bucks a for a roll which covered most of my 1800 square foot floor. I bought it from a local industrial/construction supply house.

hey Brian.....finally built mine (well, almost finished). I don't feel like re-loading all the pics so follow the link if interested :)

Nice job Brian. I had no time to build so I went the easy route and bought an old warehouse.
