What kind of base do I need for an above-ground pool liner?

A standard sand base for an above-ground pool would be 3-4 inches of fine mason sand or play sand throughout the whole bottom of the pool and 7 inches on an angle (this is referred to as a "cove") against the pool wall. Air pockets should be avoided during liner installation. If necessary, fill in any low areas with sand.

If you are installing an inner liner, then you will also need to install a fiberglass mat as the base material for the inner surface. This should be done by laying out the pool evenly and smoothly with no dips or spikes, then cover it with another layer of sand about 1/4 inch thick. Repeat this process twice more for a total depth of 3/4 inch sand across the entire pool.

The purpose of this base material is to provide traction for your installer as they go over any rough spots in the yard surrounding the pool. Any stones or concrete that are found their way into the base area when filling in the yard should be removed because they will cause problems for your pool's filter system and may even require replacement parts. Be sure to wear protective clothing while working around the pool.

Now that you have your base prepared, it's time to add the liner. Start at the far end of the pool and work your way toward the other side using the directions provided with your pool filter. Make sure to follow the instructions carefully and use the supplied tools whenever possible.

What is the best base for an above-ground pool?

Above-ground pools need the installation of a base material before the pool can be built. The most common foundation material is masonry sand or stone dust. Mason sand, commonly known as pool sand, is the most preferred choice since it creates a very smooth bottom layer. The depth of the base should be equal to or only slightly greater than the height of the walls surrounding the pool. This way, when water is added to the pool, it will not overflow beyond the wall lines.

The next decision to make is what type of material you want to use for your flooring. If you choose cork, then you will also need to install a subfloor below it. For a vinyl liner, any old kitchen floor would work well. It's recommended to put down some form of nonslip surface area first so you don't end up with trouble when you add heat to the water. Heating above 118 degrees F will cause the liner to melt and release chemicals into the water that can be harmful to humans.

Before you start building an above-ground pool, check with your local government authority about any requirements that may apply to your location. Some require you to have a permit while others may limit how large you can make the pool.

Pool construction is fun and exciting, but it's important to take safety precautions too.

What kind of sand do you use under a pool liner?

You want very fine sand that is devoid of rocks and stones for the base of your pool. This sort of sand is also known as mason sand, masonry sand, or mortar sand. While mason sand is the most common alternative, concrete sand is also an option. Before you add any other material to the base of your pool, such as gravel or pebbles, first try using mason sand. If this isn't enough traction for your feet, then add more.

Mason sand is available in different sizes and shapes. Make sure to use the right amount for your pool. Too much mason sand will cause your feet to sink into the sand at the bottom of your pool. Not enough mason sand will cause you to slip when walking on the surface of the pool. For best results, use a sieve to pick out any large pieces of rock before adding it to your pool.

Mason sand is easy to clean and does not need to be replaced often. However, due to its porous nature, it may require resealing once in a while to keep water from leaking into the sand bed beneath your pool deck.

Concrete sand has the same benefits as mason sand for your pool's base, but it is usually cheaper. Like mason sand, concrete sand is available in different sizes, so be sure to use the right amount for your pool needs.
