Vapor Barrier Under concrete pole barn

[pearltsi]

Ok, I did my searches and didn't find any pictures or info. Putting a vapor barrier under my concrete in a pole barn. I came up all the walls a little to "surround" the concrete. Its laid all inside the space. Now my question is.

What do I do with the vapor barrier by my garage door openings?

Or, Should my concrete be stopped directly under the garage door or even with the outside of the building?

Just need some help from the people who have done this already. Thanks.

I ran my VB to the inside edge of the garage door and the concrete to the outside edge.

I also dug down under the garage door so the cement under the door is 18" thick.

Don't worry about the door area , get it as tight as you can to the wall and pour .

I used a footer on my pole barn slab , the outside edge is flush with the wall but has a step to control water.... the vapor barrier stops at the footer as you can see in my pictures. Hope this helps , lemme know if you need more clarification as I have more pics.

Mine looks very similar but they ran mine all the way to the edge.
