Are you saying the 1/2" or 3/4" of plywood around the pour once it
disintegrates will create a void that wide between the earth and the
pour???? And then the concrete mass could shit by 1/2" or 3/4"
I seriously doubt that... and think nature wouldfind a way to make up
for the "slack" as rains came and went the soil would ultimately be
found near the pour...
