I need to raise a large 20 x 24 foot shed about 2 feet. I was built
using 5-4x4 beams (should have been 6x6), 2x8 floor joists, and sits
on 25 pads about 16" off the ground. There is no electric or plumbing
going to/from the shed. just a large shed I want to make into a
workshop, but need to raise as in normal very heavy rains, flood water
comes up to the bottom of the joists. Any ideas on raising this thing
myself? -- thanks
You can rent a small crane. (one idea) Not as expensive as you may think.
Other than that it would be jacks and beams........
I have raised many structures that way, and placing a 4x6 or larger
(preferable)under the floor and raising both sides using blocks to support
the lift is a way to go.
If the building is structurally sound a person can raise one side at a
If the subfloor is out of the way, a person could use jacks and house jacks
in the interior......

This is just big enough to be difficult... You can do it probably with
a series of bottle jacks, shoring timbers, and a lot of sweat.
Be very careful not to get under the building while raising it, an
accident would flatten your entire day.
A lot of the problme will be determined by how rigid the floor
structure really is. You'll want to empty the building as much as you
can (everythign out. Are there any load bearing columns in the
building? They may complicate lifting some. With luck, and a realy
rigit floor you may get away with using four jacks, one at each
corner. If not rigid enough, then perhaps eight will be needed. If
there are columns and the floor is 'soft' it gets much more difficult:
you'll need to put in temporary supporting members to transfer the
weight to the outside parameter.
Have you considered digging a ditch around the perimeter and
providing a drainage path for those rains?. It seems to me that
16 inches is a nice height above the ground, and if your water builds
that much, the soft ground could be a bad thing for any supports you
put under the building after raising it.
Also, digging a shallow ditch and drain path could be a lot
easier, IF your terrain will allow it......
Just a suggestion, but I would consider the drainage problem before
going to the trouble to put the shed any higher.
