An above-ground pool is a fantastic addition to any backyard, but its longevity and your comfort depend heavily on what lies beneath the liner. A proper base pad is the unsung hero of your swimming setup, creating a protective barrier between the delicate vinyl liner and the unforgiving ground. Without this crucial layer, you risk punctures from rocks, roots, and debris, leading to costly repairs and a shortened pool life.

The market offers a variety of materials and sizes, from heavy-duty geotextile felts to durable polyethylene mats.

Buying Guide: What to Look For in a Stable Base for Your Above Ground Pool
When I set up my first above ground pool, I thought a flat patch of grass would be enough. I learned the hard way that a proper base is everything. It’s the difference between a pool that lasts for years and one that sags, tilts, or gets a torn liner after just one season. Your pool’s base is its foundation, and getting it right is non-negotiable for safety and longevity. Let me walk you through what I now consider when choosing the best base options for above ground pools.
First, you need to think about drainage. A base that traps water is a recipe for disaster. It can lead to a soft, muddy mess under your liner, promote mold and mildew, and even cause the pool walls to sink or shift. Materials like crushed stone or gravel are fantastic because they create a permeable layer that allows water to flow away from the pool floor instead of pooling underneath it. I always make sure my base slopes very slightly away from the center to encourage runoff.
Next, consider comfort and protection. While a stable foundation is the primary goal, you also want a surface that feels good underfoot and protects your pool liner from sharp objects. This is where a layer of masonry sand comes in. After leveling and tamping my gravel base, I add a smooth, compactable layer of sand. It fills in any small gaps and creates a soft, uniform surface that cushions the liner. Some people also use foam pool floor padding on top of the sand for an extra layer of comfort and protection against tiny rocks or roots.
The final, and perhaps most critical, factor is compaction and leveling. No matter what material you choose, if it’s not level, your pool won’t be either. An unlevel pool puts immense stress on the walls and can lead to a catastrophic collapse. I use a long level and a tamper to methodically compact and check every section of my base. It’s a tedious job, but it’s the most important step in the entire process. I never rush it. Whether you’re using a traditional sand and gravel base or a modern synthetic base like a foam pad, taking the time to create a perfectly level and solid foundation is the best investment you can make in your pool’s future.
FAQ
Can I just put my above ground pool on dirt or grass?
I strongly advise against it. While it might seem easier, placing your pool directly on dirt or grass is asking for trouble. The ground is uneven, soft, and full of organic matter that will decompose, creating pockets under your liner. It also offers poor drainage, leading to a muddy base that can damage your pool’s structure and liner. Always take the time to prepare a proper base; it will save you from headaches and potential repair costs down the line.
What is the purpose of the sand under an above ground pool?
The sand layer, often called a “sand cove,” serves a couple of key roles. Its primary job is to create a smooth, soft surface that protects the bottom of your vinyl liner from punctures by small stones or roots. It also makes the pool floor much more comfortable to walk on. I use it as a final leveling agent to fill any minor imperfections in my compacted gravel base, ensuring a perfectly uniform surface for the pool to sit on.
How thick should the base be for my pool?
The thickness can vary, but a common and reliable approach I use is a 2- to 3-inch layer of compacted gravel or stone dust for the main sub-base, followed by a 1- to 2-inch layer of leveling sand. If you’re also using a protective foam pad, that typically goes on top of the sand and is about half an inch thick. Always check your pool manufacturer’s specific recommendations, as some may have particular requirements for their warranty.
Is a foam pad better than sand for the base?
Foam pads and sand aren’t necessarily an either/or choice; many people, including myself, use them together. A foam pad on top of a well-leveled sand base provides superior comfort and an extra barrier against punctures. It creates a fantastically smooth, carpet-like feel underfoot. However, a foam pad is not a substitute for a properly prepared and level sand and gravel foundation. It’s an enhancement, not a replacement.
What type of sand should I use for the pool base?
You must use masonry sand or “torpedo” sand. Do not use play sand or beach sand. Masonry sand is coarse, washed, and free of clay and organic material, which means it compacts well and drains effectively. Play sand is too fine and can retain water, turn mushy, and even wash away, creating voids under your pool liner. Getting the right sand is a simple step that makes a huge difference in the stability of your pool’s foundation.
Do I really need to compact the base material?
Yes, absolutely. Compaction is what turns loose gravel and sand into a solid, stable foundation. Skipping this step is one of the biggest mistakes you can make. An uncompacted base will settle over time, especially under the weight of thousands of gallons of water. This settling is never even, leading to an unlevel pool and all the associated problems. I use a mechanical plate compactor for the gravel and a hand tamper for the final sand layer to ensure a rock-solid base.
