OK. talked to contractor, he was less than co-operative so I rented small excavator and went to it myself.
Dug out the the old "clay" the contractor said he "packed" in and found that he didn't really pack it in at all or even get all if the old sand out. At the locations of the most noticeable leaks, I found veins of sand through the clay.
I dug out 3 sides so far and pack 2' of fresh, dry, (well mostly dry) clay in its place in 2 x 12" layers , compacting with HOPAC on excavator.
So far it seems to have stopped all but 2 tiny little seepages which seems pretty decent.
only thing left is to do small beach area which i wasn't going to do but i have 2 days left on rental so I might as well.
Is it correct to assume all dug ponds leak a little?
