Many do-it-yourselfers installing an above ground swimming pool for the first time have questions regarding how to properly install a swimming pool with a sand base, foam cove and liner floor pad.

This article will illustrate the correct way to accomplish this in order to make the installation go smoother and protect the pool liner and pool wall from being damaged.

The information in this article is provided and referenced directly from each swimming pool manufacturer’s installation and safety instruction manual (Wilbar International, Trendium Pool Products and Trevi).

One of the biggest problems that we see is with the height of the base beneath the above ground pool liner. When the sand base is not high enough there is excess strain put on the pool liner and pool wall, and this tremendous weight of the water can easily cause the vinyl pool liner to “blowout” and/or the metal pool wall to be pulled down.

Above ground pool liners are not built to withstand water weight, they are simply made to line the inside of a pool to hold the water. Therefore, when installing a new above ground swimming pool or a new above ground pool liner it is extremely important to make sure that the vinyl pool liner is supported by the proper base. There should be NO AIR SPACE between the vinyl pool liner and the base that it should be resting on.

Step 2

After installing the 3″ sand base, lay the liner floor pad on top. Please note your liner floor pad is pre-cut to fit your pool’s exact dimensions.

Attach the pool cove (foam) directly on top of the liner floor pad by removing the adhesive backing and sticking it to the metal pool wall (where the liner floor pad meets the metal pool wall).

This is the completed above ground pool liner installation. The vinyl pool liner should be completely supported by the pool base to avoid any stress or damage to it or the metal pool wall.

Above Ground Pool Installation Items

The following are links to various sections on our website ThePoolFactory.com where you can select pool liner installation items based off your above ground pool size.

Pool Cove (Foam)

Pool Cove is foam that easily peels and sticks to the inside base of the pool wall. The foam pool cove is 3-3/4 inches high and must be installed on top of 3 inches of sand. This will give you a total height of about 7 inches, the recommended height to support the liner and eliminate stress at the seam of the pool liner.
