Yes, it is recommended that you put sand under your swimming pool. Having a layer of sand beneath the liner of your pool provides cushion and softness, helping to protect the liner from any sharp or pointed objects that might be present in the ground below.
It also helps to spread the weight of the pool more evenly, which can help to prevent the pool from cracking or sinking. Sand also helps to protect the pool from any movement in the ground, as it’s an absorbent material that can take away some of the stress put on the liner due to ground movement.
Finally, sand offers great drainage and can help to filter out any particles that can make the water cloudy.

Do you have to put sand down for above ground pool?
No, it is not necessary to put sand down when installing an above ground pool. The choice to do so is largely decided by personal preference. Some people put sand down underneath their pool liner as it provides cushioning, making the ground more comfortable and less hard on your feet.
Other people opt to not use sand as it can potentially cause gaps to develop between the sides of the pool and the ground. When installing an above ground pool, it is important to make sure that the ground is level and well-compacted.
If the ground is not level and properly compacted, it can result in problems once the water is in the pool. Additionally, sand can help to level out some of the uneven spots in the ground. If a person decides to put sand down for their above ground pool, it is recommended to use coarse, washed river sand to best support the pool weight.
Additionally, the sand should not be deeper than 2-3 inches.
What is the reason for sand under pool?
The use of sand under a pool is twofold. Firstly, it provides a secure foundation to help ensure that no settling or cracking will occur. Secondly, it is also used as a filtration system. Filtration systems are important as they help reduce the amount of algae and bacteria that can accumulate in the water.
The sand acts as a natural filter, trapping large objects and debris, while allowing smaller particles to pass through. It is important to choose the right type of sand for the filter, as some types of sand may contain impurities or other elements that can be harmful for the pool.
Sand should also be kept well aerated to ensure the best filtration possible.
What kind of sand do you use under a pool?
The type of sand used under a pool depends on the location and the pool environment, so it is best to consult a professional to determine the most appropriate sand for your needs. Generally, if a pool is located in a warm climate and is outdoors, a coarse, washed stone or pea gravel is preferred.
If the pool is indoors and in a cooler climate, a finer type of sand is usually more suitable.
It is important to note that a pool can sit on a combination of sand and stone at the same time. This is often needed to accomplish proper compaction for the pool foundation. Different types of sand are also used for other purposes such as backfilling the voids around the pool or skimmer.
When installing sand and stone around a pool, it is essential to use quality materials that have been properly screened and cleaned. It is also important to ensure that the sand and gravel is spread evenly and raked flat to ensure a consistent foundation for the pool.
Finally, the sand should be tested for compaction to make sure the pool is firmly anchored in place.
What is the thing to put under an above ground pool?
If you’re installing an above ground pool, one of the most important steps is creating a safe and secure foundation. The thing to put underneath an above ground pool is something that is firm, flat, and level, such as sand, gravel, or interlocking foam or rubber pads.
It is important to ensure that the surface is correctly graded and extends at least 8” beyond the perimeter of the pool or the entire area between the pool and the walls should be filled with sand or gravel.
For optimum safety, we recommend laying down a weed blocking cloth, as this prevents grasses and weeds from growing up around the pool which can be a tripping hazard. After this, you may want to install interlocking foam or rubber padding for additional padding and cushion.
This will also further protect the underside of your pool and the ground underneath from damage.
In the event of a heavy rain or flooding, it is important to ensure that the surrounding area is properly graded, such that the water will flow away from the pool. This prevents standing water around the pool, which would significantly reduce the pool’s stability and shorten its lifespan.
If the area is not adequately graded and/or an inadequate foundation has been used, the pool could shift or settle, resulting in costly repairs.
For all of these reasons, making sure you have a safe, level foundation underneath your above ground pool is essential for a successful installation.
How much sand do I need to put under my pool?
The amount of sand you will need to put under your pool depends on the size and shape of your pool and the type of pool you have. Generally speaking, for an in-ground pool, you will need to purchase enough sand to fill the area under the pool to a depth of 2 to 4 inches, or 50 to 100 millimeters.
You should also purchase a 30-50 lb. bag of pool-grade polymer sand to mix with the sand to create a stronger, more permeable filtering base. The total amount of sand needed will then be based on the amount of area to be filled – typically 2–3.
5 lbs. of sand per square foot of pool area. The amount of sand required will also vary based on the type of pool you have; for example, a vinyl-liner pool may need to have more sand in order to help create the right shape for the bottom of the pool in order for it to properly fit the vinyl liner.
Another key factor to be taken into account when calculating how much sand to purchase for a pool is the type of soil at the pool site; if the soil is rich, more sand may be needed. In addition, the quality and shape of the pool should also be taken into account; for example, for an above-ground pool with a tile design, you may need to use more sand to ensure the tiles are properly set and secured in place.
Therefore, the amount of sand you will need to purchase for your pool will be determined by a variety of factors and will vary from pool to pool. It is best to speak to an expert or your local pool supply store to determine the amount of sand you will need specifically for your pool.
Can you put a pool directly on sand?
In short, no. It’s not recommended to put a pool directly on sand. Although sand is a relatively level surface and great for supporting the weight of a pool, it can cause problems down the line. Sand does not offer the same foundation and stability as a concrete surface.
Over time, the sand can shift and settle, causing the pool to become unlevel and create instability. Moving a pool after installation typically becomes very costly and time consuming. It is best to put a pool on a hard surface, such as poured concrete, a concrete slab, or a raised deck, or a combination of these.
Another alternative is to use pavers. It is also important to use a quality sand filter and backfill to ensure a firm foundation and protect the integrity of the pool. The backfill should be packed and level, and the filter sand should provide a cushion between the pool and the ground.
How do you prepare the ground for a pool?
Preparing the ground for a pool is an important part of the pool-building process. Depending on your climate, the best time to prepare the ground for a pool may vary. Generally, most pool installations should begin after all risk of frost has passed.
The first step in preparing the ground for a pool is to clear it of any vegetation, including grass, weeds, and shrubs. This can be done by hand or with a heavy-duty landscaping machine. Once the ground is clear, it’s time to shape the foundation.
This involves excavating the ground to ensure a level surface, and to set the specifications for the size of the pool. It’s important to keep in mind the surrounding landscape and matched the foundation to it.
In addition, the excavation should be sloped to ensure proper drainage.
After the foundation has been established, the area must be leveled and compacted. This can be done by professionally using a plate compactor, or a combination of hand tools, to ensure that the ground is even and stable.
The final step in preparing the ground for a pool is to add material such as sand and gravel, to provide a cushioned layer that will protect the pool from settling and upheaving. This can be done with a power-trowel for maximum efficiency.
Overall, it’s important to prepare the ground for a pool with the utmost care and attention to detail. Proper surface preparation is essential to ensure a long-lasting, beautiful pool.
What should I put down before installing an above ground pool?
Before installing an above ground pool, there are several things that should be taken into consideration. First, you should research and understand the local pool regulations for your area. Make sure to properly prepare the space that you plan to set up the pool in.
This will include the removal of any plants, stones, sticks, or anything else that may potentially cause damage to the pool. You may also want to consider adding a layer of sand to the designated space before placing the pool.
Furthermore, you should make sure the area is level and also measure the space to make sure it is large enough. It is also important to make sure all necessary materials come with your pool such as the pump, filter system, skimmer, ladder, liner, pool cover, vacuum, and any other accessories that you may require.
Lastly, it is essential to read the instructions thoroughly and contact customer support if you are having any trouble with installation or have any questions or concerns.
Do you need a sand base for a pool?
Yes, it is important to have a sand base for a pool because it provides a flat, even surface on which to install the pool and prevents the movement of the pool walls during the installation process. A sand base also helps to reduce bumps and air pockets that are common in the basement of an above-ground pool, which can lead to structural issues in the future.
Additionally, the sand base helps to ensure a more consistent water level in the pool, and makes it much easier to install the pool liner, since the sand holds the material in place while it is being installed.
Finally, the sand base improves the longevity of the pool, since it helps to protect the structure of the pool from the shifting of the ground beneath it.
Why don’t you put sand under a pool?
Sand should never be used as a base for an above ground pool because it does not provide adequate support for the pool wall. Sand is also a poor choice for use as a pool base, as it will settle or migrate, creating an uneven and unstable foundation.
Instead, an undersand pad or liner pad should be used to provide a solid foundation. An undersand pad or liner pad is made out of a durable material, such as PVC, to create a flat base and prevent the pool wall from settling and shifting over time.
Additionally, sand is prone to erosion and could cause the pool wall to become unstable if the sand is abnormally wet or heavy. Lastly, sand can be an eyesore and difficult to maintain since it can easily get kicked out of place.
Therefore, an undersand pad or liner pad should always be used as the base for an above ground pool.
Can you put too much sand in a pool filter?
Yes, you can put too much sand in a pool filter. If too much sand is added, the filtration efficiency of the pool filter will be greatly reduced as the sand can create blockages and clogs within the filter, which will limit the amount of water that can be pushed through.
Too much sand can also cause problems with the backwash cycles, which make it difficult to properly clean and rinse the filter. Additionally, using too much sand in the pool filter can cause a greater amount of wear and tear on the filter pump and other components, resulting in higher maintenance costs and a shorter lifespan for the pool filter.
For these reasons, it’s important to make sure that you use the recommended amount of sand for your pool filter.
Should I put sand or soil under my pool?
Your answer depends on whether you are installing an above-ground or in-ground pool. Generally, if you are installing an above-ground pool, you should put sand under the pool liner to help protect it and provide a level surface.
However, if you have an in-ground pool, it is best to fill the gap under the liner with soil. This helps to keep the liner in place, evens out any uneven surfaces, and allows for better drainage. It is important to check with your local pool installation company to confirm what material they recommend for your pool before beginning installation.
How often should you change sand in above ground pool?
It is recommended to change your above-ground pool sand every five years. This can vary however depending on factors such as how often you use your pool as well as the quality of the sand. If your pool is used frequently, it may be more beneficial to change it more often as dirt, oils, and contaminants can build up quicker.
Additionally, if your current sand does not have a high-quality grade, it may need to be changed more often. In general, it is best to check the sand quality every one to two years and replace it when necessary.
How do I know if my pool sand needs replacing?
First, check the labels on the filter tanks to see if they specify the lifespan of the sand. Depending on usage and water circulation, most sand should last 3-5 years. If in doubt, test the sand by rubbing some of it between your fingers.
If it feels gritty or sharp, it’s probably time for a change. Additionally, if the pressure gauge reads higher than normal (8-10 pounds is the recommended level) it might be a sign that the sand is becoming clogged with fine particles that cannot be adequately filtered away.
Lastly, look for uneven pools of water in the sand bed or on the floor of the pool. Poorly-shaped grains of sand can lead to this type of pool level variation, which is another sign that a replacement is necessary.
