We installed a brick patio a week ago and today I rented the plate
compactor to go over the pavers. After going over them, one area
towards the side is now spongy while the rest of the patio seems firm
and solid. Do I need to do some kind of repair on this or is this
normal? Can I expect the spongy area to settle down after a while or
will it just get worse?

We have a 6-inch lime-stone base that is flat and well compacted with
1-inch of sand between it and the pavers.

Thanks,
