How Much Sand for an Above Ground Pool?

For an above ground pool, sand is usually used to help level the ground, not as a deep foundation. The right amount depends on the site and your manual.

Above ground pool: how much sand is required?

The short answer is that you need only what is necessary to put down a smooth, level base for the pool. There is no call for a deep bed of sand that will eventually shift. The quantity is dictated by the size of the pool and the lay of your land, as well as the manufacturer’s specifications. In some cases, a thin layer for leveling will do; in others the manual may specify an entirely different material.

A word on buying sand

Your first port of call should be the pool manual. It will give you the definitive answer on installation requirements. After that, have a look at the yard and determine if sand is in fact the solution.

Here is a good way to go about it:

1. Put in some markers for the pool footprint and survey the area for any high or low spots. 2. Do away with the high ground rather than attempting to build up the foundation with sand. 3. If the manual allows, use sand to fill in minor depressions. 4. Before putting the pool in, check the level from a few different angles.

You can employ a 2x4 and a long straight board with a level to find unevenness, but make sure the base is truly level and not merely flat in appearance.

Which sand is suitable?

There is no one size fits all when it comes to the type of sand. While many installers will opt for something like mason or concrete sand because it is clean and fine, the brand and its guide are what matter. Should the manual put forward a particular base material, stick with that over any online advice.

Keep in mind: - The sand must be free of rocks, roots and other debris. - It has to be compacted to bear the weight of the liner and frame. - Avoid a loose, thick layer; under the weight of the water it will shift and cause wear.

When is there too much?

Sand is meant to fine tune a site, not to be the primary method of correcting a sloped yard. If you are using it to mask poor preparation or soil that is not holding firm, you have gone too far. Ground that is poorly draining or has a pronounced slope calls for excavation and compaction before you even think of adding sand.

Mistakes to steer clear of

Some of the more common errors include trying to level a badly sloped lot with sand instead of removing the high spots, or leaving grass and construction debris in place. Others will ignore the manual and make an educated guess at the depth of the base, or fail to do a final check of the level before the pool is filled.

And the filter sand?

Do not mix this up with the ground base. Sand for the filter is a separate matter and should be measured per the filter manual.

Time to get a professional?

If the yard is soft or unstable, if water runs toward the pool site, or if you have a significant slope to contend with, a qualified installer is the way to go. Even if you have done the prep and cannot get the frame to sit right, make the call. If there is any doubt as to what the manual permits in terms of leveling, seek help before you put water in the pool. An uneven base is difficult to remedy once the pool is full and it can compromise the safety and longevity of the structure.
