   So the column bases are just resting on pads a few inches under the gravel -- we can see one base in the foreground of the picture?

   Why do the columns need to be replaced?  Are they rusting out?  Why do you want to raise the pads?

   How large are the pads?  How are the columns anchored to the concrete?

   Generally, there should be no problem (other than with the cramped quarters) with drilling holes in the existing pads, inserting rebar, and pouring more concrete on top, assuming you're only talking 6 inches or so of added height.  Would be messier if you want fully concrete piers all the way to the deck framing.

   Hello and Thank you:

   The outer steel is flaking off exposing the concrete filler. The piers were poured unformed. the tops are 10 inch rough diameter. One column was loose, I removed it. The method used for that one was, they let the pier cure below grade, put plastic on top & set the column, filled  around remaing hole depth with concrete. I woud like to raise the piers so that if I use PT wood posts the bottoms will be clear of the ground.

   For the one I replaced I used a Simpson EPB44PHDG post base, and SET epoxy anchoring adhesive. Because the top of the pier was so much below grade the bottom of the new post was right at ground level. I am thinking if I get the piers higher, that would be better for the new posts.

   Thank You, for helping.
