Setting up an above-ground pool is an exciting venture, promising hours of fun and relaxation during the warmer months. However, a crucial, often overlooked aspect is what you place under the legs of your pool. Neglecting this step can lead to a myriad of problems, from a tilted pool to damaged liners and even compromised structural integrity. This article dives deep into the importance of proper pool leg support, exploring suitable materials and offering practical advice to ensure your pool setup is safe, stable, and long-lasting.
Why Proper Pool Leg Support Matters
Proper support under your pool legs is far more critical than simply leveling the pool. It’s about distributing the immense weight of the water evenly, preventing damage to your pool liner and frame, and ensuring the long-term stability of the entire structure.
The Weight Distribution Problem
Imagine the sheer weight of thousands of gallons of water concentrated on a few small points of contact – the pool legs. Without adequate support, these legs will sink into the ground, especially after a heavy rain. This sinking can cause the pool to become uneven, stressing the liner and potentially leading to tears or leaks.
Preventing Liner Damage
Uneven pressure on the pool liner is a recipe for disaster. When the legs sink, the liner stretches unevenly, creating weak spots that are vulnerable to punctures and tears. Replacing a pool liner is a costly and time-consuming task, easily avoided with proper support.
Ensuring Frame Stability
The frame of your above-ground pool is designed to support the weight of the water evenly. When the legs sink, this equilibrium is disrupted, placing undue stress on certain parts of the frame. Over time, this can lead to warping, bending, or even collapse, rendering your pool unusable.
Protecting Your Lawn
Beyond the pool itself, consider your lawn. The immense weight of the pool legs will compress the soil, leaving unsightly indentations that can be difficult to repair. Placing protective barriers under the legs prevents this compression, preserving the beauty of your outdoor space.

Why is it important to put something under my above-ground pool legs?
Placing protective materials under your above-ground pool legs is crucial for several reasons. Firstly, it helps distribute the weight of the pool and its water contents more evenly across the ground. Without this distribution, the legs can sink into soft or uneven surfaces like grass or soil, potentially leading to instability, leaning, or even collapse of the pool. This concentrated pressure can also damage the ground, creating unsightly and potentially dangerous holes.
Secondly, using a protective barrier prevents direct contact between the metal legs and the ground. This is particularly important if the ground is damp or contains corrosive elements. Direct contact can lead to rust and corrosion of the pool legs, shortening their lifespan and compromising the structural integrity of the entire pool. Furthermore, it helps protect your lawn or patio surface from being damaged by the pool leg’s weight.
What are some suitable materials to use under pool legs?
Several options provide excellent protection under your pool legs. Concrete pavers are a popular and durable choice, offering a stable and level surface. They are readily available at most hardware stores and are relatively inexpensive. Interlocking rubber mats are another great option, providing a cushion between the legs and the ground while also preventing slippage. These are often made from recycled materials and are weather-resistant.
Alternatively, consider using specially designed pool leg pads or leveling blocks made from hard plastic or durable rubber. These are specifically designed to support the weight of a pool and offer excellent stability. Wooden blocks can be used but are generally not recommended long-term due to their susceptibility to rot and water damage. Remember to ensure whatever material you choose is level, sturdy, and appropriate for the weight and size of your pool.
How do I ensure the materials I put under the pool legs are level?
Ensuring a perfectly level base is paramount before filling your pool. Start by using a level to check the ground where each leg will sit. If the ground is uneven, you’ll need to level it before placing any protective material. This might involve digging away high spots or adding soil to low spots and compacting it thoroughly.
Once the ground is as level as possible, place your chosen material (pavers, mats, etc.) under each leg. Use a level on top of the material to confirm that it is perfectly horizontal. You can adjust the level by adding shims (small pieces of wood or plastic) under the material until the level reads correctly. Double-check the levelness of all the legs relative to each other to ensure the pool is sitting evenly. This step is crucial for preventing uneven water distribution and potential structural issues.
What happens if I don’t put anything under my pool legs?
Ignoring the need for protection under your pool legs can lead to a number of problems. The most immediate consequence is the potential for the legs to sink into the ground, particularly after the pool is filled with water. This sinking can cause the pool to become uneven, stressing the liner and frame and potentially leading to leaks or even collapse.
Furthermore, direct contact between the metal legs and the ground can accelerate corrosion and rust, shortening the lifespan of the pool and weakening its structure. It can also damage the surrounding landscape, leaving unsightly indentations or damaging patio surfaces. Ultimately, neglecting this simple precaution can result in costly repairs or the need to replace the entire pool prematurely.
How often should I check the materials under my pool legs?
Regular inspection of the materials supporting your pool legs is essential to ensure ongoing safety and stability. It’s recommended to check them at least monthly, especially after periods of heavy rain or significant changes in temperature. Look for any signs of sinking, shifting, cracking, or deterioration of the materials.
If you notice any issues, address them promptly. This may involve releveling the materials, replacing damaged pavers or mats, or adding additional support if needed. Ignoring these warning signs can lead to more serious problems down the line. A proactive approach to maintenance will help prolong the life of your pool and prevent costly repairs.
Can I use sand under my pool legs?
While sand is often used as a base for the entire pool liner, it’s generally not recommended as a primary support material directly under the pool legs. Sand tends to shift and compact over time, especially when exposed to moisture and pressure. This can lead to uneven settling of the legs, compromising the pool’s stability.
However, you can use a thin layer of sand *under* the pavers or other solid materials you’ve placed under the legs, to help level them initially and provide a more even surface. Just be sure to use the sand sparingly and compact it well before placing the pavers or pads on top. The primary support should still come from a solid, non-shifting material like concrete or rubber.
What size material should I use under the pool legs?
The ideal size of the material placed under your pool legs depends on the size and weight of your pool. As a general guideline, the material should be large enough to fully support the base of the pool leg and provide a stable platform that prevents sinking or shifting. For most above-ground pools, concrete pavers that are 12 inches by 12 inches are a good starting point.
However, for larger or heavier pools, you may need to use larger pavers or mats to distribute the weight more effectively. Consider using multiple smaller pavers together to create a larger, more stable base if needed. Ultimately, the key is to ensure that the material is strong enough and large enough to prevent the pool leg from sinking into the ground and that it provides a level and stable support for the entire pool structure.
