Floating rubber molded pond.

[Tokay]

Im sure some of you have had the same problem, like me and 2 of my friends.
I have a 125 gallon rubber molded pond from home depot that i put into the ground. During the heavier raning seasons of southern cali, the ground would soak up more water then usual and the pond would begin to float out of the whole with a pool of water under it. The area around it doesn't flood, and has a drain path in the back. My friends same size pond floated out with alot less dirt around it and surround by concrete. Im haven't heard of any cures for this problem. Anyone know of any fixes? for now my pond is on my pato held up by cinder blocks. Or is there just no way around this and i have no choice but to build a huge non-rubber pond instead? thanks for your time

A couple possible cures, first, make sure the pond is full, if not it acts as a boat, second, you can weight it down with gravel or stone, third, use ground anchors (look loke giant corkscrews) through the pond floor then sealant around them. One problem with some types of soil is that it expands when saturated so in that case the ground actually squeezes the pond up out of the hole, the cure for that is an oversized hole with the excess space filled with coarse sand or peagravel. Do not pack it when backfilling.

That sounds right.. I Have oversized the hole and used gravel and it has worked,

you can also run drainage tile around the pond to help the water drain away from it
