Why It’s Important to Choose the Right Material to Put Under Your Portable Pool

Picture shows an above ground pool set up on grass. It’s important to choose the right material to go under your pool.

When it comes to choosing what to put under your Intex or other inflatable pool such as Bestway and Summer Waves pools, there are several choices. Each under pool material has its pros and cons.

Here’s a few of the benefits of choosing the right material to put under your above ground pool:

  • Protects the bottom from abrasions and punctures
  • Prevents Mould/Mildew
  • Smoother under your feet
  • Makes cleaning easier
  • Stops damage from grass and insects

Where to Put an Above Ground Pool?

Before deciding on what to put under your above ground pool, you need to decide on where to put your Intex pool. It’s best to located it away from overhanging trees. It stay a whole lot cleaner that way.

As for the base for your above ground pool, popular options are grass, concrete, pavers, gravel, dirt and on decks.

Concrete is probably the best option since it is usually 100% level and smooth. Also, grass can’t grow through concrete and animals and bugs can’t damage or burrow through it either.

Grass or dirt is also another great option, as long as it has been properly levelled and you’ve killed off the grass first.

You could put your pool on pavers, however the weight of the pool may compress the pavers and move them out of shape if the base isn’t prepared properly.

What to Put Under Above Ground Pools or Intex Pools?

After you’ve decided where to put your pool, it’s time to decide what under pool mat you will use for your Above ground or Intex pool. The right material can extend the life of your pool.

Many people are looking for an alternative to sand. We have 4 sand alternatives in our list of the most popular materials to put underneath an above ground pool. And these materials work whether your pool is on grass, pavers, gravel or a concrete pad:

  • Interlocking Foam Tiles 
  • Carpet
  • Intex Ground Cloth
  • Flooring underlayment 
  • Sand 

One thing to note is that these materials are used after you’ve levelled and prepared the site.

How to Choose What to Put Under a Pool

There are five main things to look out for when deciding which material is best to put under your pool.

  • Breathable
  • Resistant to Punctures
  • Thickness and Feel
  • Easy to Install
  • Cost

Having a breathable material will help prevent mildew and mound which is caused by trapped moisture.

Some materials are naturally tougher than others, such as commercial under pool pads. This is more important if you plan to put your pool on grass or dirt.

Having the right material just feels nicer on your feet. Some people don’t mind it but having stones sticking into my feet isn’t my preference. Going for a thicker material or combining two materials together will produce a better feel.

A material that is easy to get to lay flat is also beneficial. This will mean that the bottom of your pool will be wrinkle free making it easier to clean (when vacuuming).

Lastly, when deciding on what to put under an above ground pool you want to consider how easy the material is to work with and the cost. Although carpet could be free (if you’re lucky), it’s not easy to cut and could be quite a lot of effort to install.

Now let’s take a look at the most common above ground pool pad ideas.

6. Sand

Is sand a good choice to go under a pool?

Should you put sand under your above ground pool?

Sand under an above ground pool is suitable for a soft base under your above ground pool. However, it shouldn’t be used to level the ground underneath a pool or as a fill material to build up low spots. Sand is good to go over a proper base like crushed stone, pavers, concrete if prepared properly.

Do you have to put sand under your pool?

It’s not necessary to use sand under all above ground pools. In most cases, for inground vinyl liner pools, sand will be used.

Alternatives to Sand Under Pool

Alternatives to sand include foam pads, tarps, carpet. Many people prefer foam pads over sand as they give a more cushioned feel.

Although it’s easy to put down and level and it may seem like an ideal material, sand can easily erode and get partially washed away in heavy rain if it is not prepared properly. Animals and bugs also have been known to tunnel through it. Proper preparation includes levelling, wetting the sand and then tamping or compacting it and letting it sit until it hardens.

If this is not done, it could cause your pool to shift or at best, you will feel “holes” or dips under your feet when swimming where the animal has been digging.

– Easy to lay and level
– Low cost material

– May move or erode over time
– Animals and bugs can tunnel through it

6 thoughts on “What to Put Under Above Ground Pools (Top 6 Materials)”

  1. Great article. Can you elaborate more on potential issues of above ground on top of pavers. Is their a weight limit to check for? Additionally, how does more measure for space (ie room for slanting supporting metals around rectangular or oval pool). Thank you!

    • Placing an above-ground pool on top of pavers can be done, but it’s essential to consider several factors to ensure safety, stability, and proper installation. Here are some potential issues and considerations:

      1) Weight Limit: Pavers are typically strong and durable, but they still have weight limits. You mostly need to verify that the weight distribution is fairly even and not concentrated onto only a few pavers.

      2) Level Surface: Pavers should be laid on a level surface to provide a stable foundation for the pool. Any unevenness or sloping in the pavers can affect the stability and integrity of the pool structure. Ensure that the pavers are properly levelled and compacted before installing the pool.

      3) Site Preparation: The pavers will only be as good as the ground under them. The ground needs to be solid and packed down or you risk the pavers sinking.

      4) Support Structure: The supporting structure of the pool, including the metal frame and support posts, should be designed to accommodate the pavers underneath. Additional measures may be necessary to provide adequate support and stability, such as using shims or adjustable feet to compensate for uneven pavers or sloping surfaces.

      Hope that helps.

    • Make sure the pool is on a solid surface to start with. You can use a concrete pad, asphalt surface or possibly pavers. Pavers may not be suitable for large pools though. It depends on how they’ve been installed. At the end of the day, the ground needs to be level and not soft. You don’t want the ground moving under the pool.
