Above Ground Swimming Pools! Packing The Sand Bottom.
One of the most important parts of installing an above ground swimming pool, is making the bottom of the pool as flat and smooth as possible. Every above ground pool is usually installed using fine mason sand as the material for the bottom. You can use a vermiculite base, and some are installed with foam. The additional cost for these options is normally not worth it, so mason sand is the material of choice.
In dealing with sand one thing to remember is that the sand will shift and move over time. We stress to our above ground customers that even with compacting the bottom the way we do, and brooming the sand as flat as possible, you can still end up with depression spots and little imperfections.
One of the things we do see alot in doing liner changes on above grounds, is that the majority of installers do not get there bottom flat. Most times the sand has some pretty good high and low spots. This is due to the installer not taking time to do the bottom right. Remember the water weight will not flatten out the bottom of your pool. The water will help to finish compacting the bottom, but if there are high and low spots, that's what you will have.
In this video you can watch how we do the bottom on an above ground pool. Make sure you ask the company you but your pool from how they do the bottom, and do they compact it? Very important!!
