Skirt board heaving

[Pechinger]

Has anyone had their skirt board lift on a pole barn?
I built my garage last summer/fall and now the tin has warped in some spots and even creased and ripped screws out.

My poles are 7ft in the ground and we have had a relatively mild winter so i don't think the posts are lifting. My barn has "bookshelf" style girts and a 2x6 skirt on the outside of the posts. So the tin sits on the skirt, i think this has lifted.

Any advise on what i can do?

I have been building post frame buildings for 28 years, I've never seen this happen. Can you post more details, especially your location, and some pics?

I live in North Eastern Ontario; Englehart to be specific.

Code for being below the frost line is 6ft. I have 28" holes drilled to below 7ft, backfilled with 1ft of concrete as a footing, post was set on top if this with rebar through the post and another foot of concrete poured in. Once dry it was backfilled with the dirt removed from the hole.

I am not quite sure how to post pictures. If you can give me some instructions i can get some pics.

From talking to guys who have been digging this winter, sounds like only around 3ft of frost so far.

Sounds like a typical frost heave situation. The ground has water in it, when it freezes, it expands.

Not uncommon for it to rise several inches. This winter with all of the deep freeze then thaw then freeze cycles has been bad for frost heaving.

This is a common issue with pole buildings since the slab/skirt is on the ground surface, but the posts are below the frost line.

The solution is to keep out the moisture that freezes and causes the heaving.

What is your grade, overhang, etc situation in the area of trouble ?

Welcome to Canada. If you see a pole barn it’s usually crooked in some way. Radix is correct slope your ground away and try keep moisture out if you can. Might need to create some sort of slip joint on the skirt.

The ground is sloped away fairly well. 16"overhang with no eaves trough (yet).

I'm betting you don't have snow trim either.

Snow trim and gutters should help minimize the issue.

What type of backfill do you have around the barn? Native soil or aggregate or?

Post up some photo's of the barn and the grading around it..

The "grade" around the barn right now is about 3ft of snow. Ill get some pics in the spring and assess the damage then.

Thanks!

The damage you are seeing may be from the snow pilling up against the sheeting and freezing. When I used to have my own erecting crews that was a very common repair job in the spring. We would have to remove and install new sheeting on whole walls. Usually on the north side of the building.
Are you sure the skirt board only is rising? If it is frost heave usually the whole building starts to rise. If it is the skirt board there should be a pronounced bow up between the posts and no damage at or near the posts. Are you seeing the damage from the inside?
