Shed on Stilts has sunk - how to Jack one side up 40mm?

[KevinRussell]

I have a Shed that sits one edge on a retaining wall and the other edge is supported by 4 X 4 posts in post holders.

The post holders are concreted in.

I actually made the stilted edge 20mm higher when I built it 2 years ago, anticipating a certain amount of settling but it is now around 40mm out over the width of the shed.

Does anyone have experience 'jacking up' a shed and readding supports?

Get yourself a cheap laser level and jack up.
You can pack out posts with roof slate and edging stones.

You thinking of adding more posts?

What would you use to Jack it up? There is soft soil beneath,

Put a slab of plank on the ground and a car jack.
You can also use levers.
I moved a 12 foot by 6 foot shed with my 80 year old neighbour about 6 foot with some wood to make a leaver.

Archimedes famously stated, "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world"

So you won't have a problem lifting it

a slab & a few bricks as a fulcrum and a scaffolders type plank - get someone to stand on one end, if the shed is heavy you will need a longer plank or a fatter person (they're abundant these days)

don't know if you need any special levels, visually will be good enough

I should of added. I wasn't convinced with the leaver idea the old boy suggested, but he said I'll be around later and we will move the shed if you have something to make a leaver. It moved easily. I was educated...

I have a 5 foot Concrete breaker - I guess that'll do. Thanks for the suggestions - I'll report back

Make sure you use something between the shed and jack/lever to spread the load
