just wondered why is it my pond liner has started to come loose & float
up in the water,it seems to be like an air pocket is under neath it &
its been down a month or so,ive put a few bricks in it to weigh it down
for now.


Normally means there is water getting under the liner and not draining away.
Could be lots of reasons,
a lot of rain.
high water table.
puncture in the liner.
waterfall/inlet getting behind the liner.
