My 10X12 storage building sets on concrete piers that set directly on the ground. My floor is sagging one and a half inches on one side and two and a half inches on the other, with a developing noticeable hump in the middle. I want to jack the sides up and add additional support. How do I go about doing this and hopefully avoid future sagging, thanks?

Did the piers settle or were there too few so the joists sagged? A standard automotive bottle or scissors jack can lift this weight.

Can u give us a picture?

Give more detail from piers to floor.

Metal or wood shed?

The leveling method changes according to type of floor joist u have.

The piers have settled, one on each corner and one in the middle.

It's a wood structure, standard framing, floor sets on piers on each corner and one in the middle. Floor is joist on piers with three quarter plywood subfloor. Piers set directly on ground.

Piers should be set below frost line in order for structure to minimize movement.

What is ground condition? Wet or soft? What is size of floor joist?

The 5 piers should be enough for this size shed.
