Above Ground Pool Backfill
by Jana Theaderman
(New Richmond, Ohio)
What is the best material to use for backfill, dirt or limestone? Our above ground pool has about 16-inches on one side that needs filled.
Should I use a drain pipe?
Hi Jana. I doubt if a drainpipe is needed, it sure does not sound like it.
With only back filling 16" you do not need to be concerned with something that will have to pack solid it a short period of time.
I would use dirt. The only precaution I might take is to coat the wall to prevent rust.
This could be landscaping plastic or a coating of roofing tar, but I would put something between the dirt and the pool sidewall.
Sinking Pool For Unlevel Ground
by Johnny Bonee
My pool installer sunk one end of my pool 33 inches because of my sloped back yard. I have the ASAHI Victoria 33 ft with 54 inch walls.
He instructed me to backfill the 33 inches with the dirt he removed. Is it ok to sink an above ground pool of this type 33 inches and back fill with dirt that high?
Hi Johnny. Your installer instructed you to do exactly what I instruct my clients to do.
It is not at all uncommon to have to level the ground leaving half the pool set in the ground. The pool must be level.
You have several options with this sunk in area. If you leave it as is your yard looks ugly and rain water will sit around the pool, in the trench, and rot the pool frame or cause a cove wash out.
You need to something with this area. You could leave it empty and install some sort of drainage, that would keep the water running off away from the pool, and not sitting around it.
You could pack the bottom of this trench with several inches of hard packed granite, all sloping towards the low side. This would run the water off and you could then cover the area with a wood decking.
The easiest way to deal with it is just like your installer said, back fill it with existing dirt.
If you are concerned about the dirt rusting the sidewall, line the wall with plastic before back filling, or paint the wall, below ground level, with roofing tar. Both methods provide an extra protection on top of the already factory painted rust inhibitors.
How much expense you want to put into it is up to you, but yes, I would back fill it.
