Corroded Girders

red_diesel

We have one of those old hay barns that are common enough around. Probably around 70 years old at this stage if not more. Also lean too's off either side. It's currently configured with bedding area on one side and feed passage in the middle. The bottom of the main supporting girders are extremely corroded and starting to crumble away. Probably due to dung and silage. I'm getting a bit worried as to how this affects the structural soundness of he shed and even worried it will some day lead to collapse!
Has anyone else experienced this issue with an old shed and if so how did you go about repairing?
Thanks.

Yep. Old cattle shed here built in 60s after rotting away at girders due to dung too.
Will just replace one at a time.
We'll buy the 5 girders. Use two to prop up trus while we take out first. Put new one in and keep going like that. Use the old ones then to prop up as we replace last few

i put concrete around them

neighbour has a mould for making circular concrete piers & i borrowed it

I came about 2 feet above the rusted area,

that was over 20 years ago still good to day , mightn't be possible to do everywhere

If you don't need to drive in past the pillars then what I saw done was bore a few holes in the concrete round the pillar and tap in a few lengths of rebar. Get a barrell, cut the ends off and one cut down the side, wrap it around the pillar to whatever size you want and tie it with a ratchet strap. Cover the sides of the barrell in grease and fill with concrete an vibrate. Will look a grand job.

Surrounding the effected areas with concrete sounds like the best option if you can manage it. Clean and if anything it will strengthen the shed

If it was me, I'd get a jack hammer and expose 4" or so away at the ground. Get a grinder then and clean away all the rusty stuff. It doesn't have to be a barrell either, case around it with equal lengths with timber. Put plenty rebar in there, nut just vertical, but get it around it aswell. At the top of the concrete put a small slope so that water doesnt lodge there.
After a few months then paint burnt engine oil over what's still left exposed of the girder. Should last another 50 years.:D
