Vapor Barrier in pole barn

Thu Jun 03, 2010 9:59 am

I know they put a vapor barrier under concrete now to keep moisture from coming up through it. So I thought it would be a good idea to put it under my gravel in the pole barn. After all the more moisture I can keep off of my tractors and equ the longer it will last. I was surprised how many people thought I was wasting my time. That air moving through the barn would get rid of any moisture coming up through the floor. But I still think its a good idea and did it anyway. After all moisture is always coming up from the ground especially in the spring.

Since I put the pole barn up in march and I could not get the pad level because it was frozen. I had the back part of barn set right on the ground. I had to go in and cut out 1.4 feet of ground so I could get my vapor barrier and gravel in. I took that much out so if I ever have concrete put in I will still have a foot of gravel under it.

Vapor barrier is down and ready for gravel. Tommy's getting a well deserved drink!


Gravel is going in. Tommy was loading the gravel in the pit with the loader. He had to get buckets from different areas of the pit to make the correct mix of sand and gravel. Timmy hauled it in the dump truck and dumped infront of the door. And I pushed it in and leveled it with the bulldozer.

Looks good Billy!

Are you taking any bets on how long it takes you to fill it up?? :D

I agree, I think you did good so long as you don't tear it up with equipment. Even though it is a foot deep the gavel moving and shifting from heavy equipment being on it may cause a problem.

Lookin good. I think that was smart, putting a vapour barrier down for the floor. I am planning on doing the same thing, once I get enough stock for my floor. Normally, I would share the same concerns as John... the heavy equipment might move some of the aggregate and pierce the VB. But this stuff looks like it is what 25mil or better? Looks almost like landscape fabric..

Bill is that the same stuff you use on the job?? If so I am sure it will take a beating and keep on ticking.

Billy, that is a great looking barn. One you can be proud of. :D :D

Did you insulate the roof? Around here, moisture will condense on the unisulated metal roof and it will actually "rain" (OK, drip a lot) inside the barn. It will drip to the point everything inside gets wet and rusty.

Thanks Bill

Ya got that right it was extra liner material from the last job I had and was going to thrown out so they let me have it.

It will be pretty well filled up by the end of summer. Thats where our big toys are :D

Thanks John

That stuff is more than strong enough to hold up. Plus with the way the barn is setup I can make long sweeping turns and that helps.

Thanks Rudi

It is textured so it can be used on a slope and not slide. Its thick :!: .080" or 2mm which would make it 200 mil :?:

Thanks Rick

Its been a long time coming :wink: It was all woods when I started last year. And it took us a while to decide where we wanted it in the first place.

Thanks Vince

Its not insulated. But it has felt paper and 1/2" osb under it. That is suppose to cut down on condensation. Make it quieter in the rain. And help it from denting in a hail storm.

It is a little late now, since the siding is already on, but on mine we used an item called Solar wrap. It is 4 foot side rolls of 1/2 inc fiberglass with foil on one side and white plastic on the other, put it under the roof and sides both. The difference as to temperature, etc. that just that half inch of insulation made was unbelievable, plus the condensation is almost nonexistent.

Beautiful building Cowboy ,you have inspired me as to the last building i will build .(hopefully) Not as large but definitely will support the car lift and such. I've always built with block but the pole building looks very spacious. :big afro: should be a little more affordable?

Doggone it John

Now I want to pull the tin off and put that on :D We are thinking of insulating the first 30 feet and putting in a wood stove. But that may not happen until next year.

Thanks Michael

Thats a 40x80 14' sidewall 12x14 roll up front door and 14x18 sliding rear door. And it was 34,145 built.
