Above Ground Pool Base Material

Hello, I purchased a new Sharkline Navigator extruded aluminum above ground pool (24'). This will be cut into a sloping backyard. We built new last year and "dished out" where the pool would sit. My issue is that the level was 18" too low to meet up with the upper patio. After going round/round with different opinions, I have added 30 ton of "stone dust" (1/8" and smaller") to raise the level where the pool will sit. My installer is VERY hesitant, and keeps repeating the old "I won't be responsible" phrase if it settles after installed. The stone dust has compacted very nice, and I plan on renting a plate tamper this weekend to really pound it in good, and I have already pumped 100's of gallons of water into it to get it to set up a little. Just looking for other experts in the pool field with opinions before this install ... thanks a lot



Hi. It sounds to me like you are doing everything right. There are a few things to keep in mind whenever you build up an area like this. Like you stated, you want to make sure it is thoroughly packed. This would include watering and tamping.

Another important factor is to allow a large ledge beyond the pool. Ideally a 24’ pool should be centered in a 30’ level area. Three foot is the minimum ledge I would want to see. You may, or may not, need a retaining wall to keep this filled area in place. That is not always needed but you need to sure the built up area will not wash away with the first rain.

The last precaution I would take is to make sure all of your supports sit on patio blocks. This will help a lot in case any minor settling does occur.

Setting pools on raised areas is very common and done for many reasons. In Arizona we do it mostly to raise the pool up out of an irrigated yard. Your installer is either just protecting himself or is not familiar enough with this to be able to give you good advise. I think you will be just fine.
