If you’re interested in learning to swim or swimming as an exercise for weight loss, you may have thought about having a pool installed on your property to support your new passion.

However, in-ground pools can be incredibly expensive to install, and you may not always be able to when considering the lay of the land.

An above-ground pool can be the solution, but you will need proper support, like concrete pavers for the legs holding up your pool’s lining.

Keep reading to learn more about the blocks that form the foundation of above-ground pools, if they are necessary, and more.


What do Blocks Do?

Blocks made to go under pool legs act as a form of support and prevent long-term damage to your above-ground pool by reducing or eliminating sinkage as the ground underneath your pool is compacted from its weight.

The blocks can also help stabilize the entire structure. This can prove useful during and after adverse weather conditions that might cause damage to your above-ground pool.

In other words, the blocks you might see under above-ground pool legs go a long way toward preventing damage and extending the lifespan of these structures.


What are they Made of?

As you might expect, there are several different materials that pool blocks can be made of. The materials listed below are some of the most common kinds, as well as some of their pros and cons:


  • Foam tiles – a cheap option that can be placed under the bottom of the pool and the pool legs. Not very resilient to the weight of all the water in the pool.
  • Pressure-treated wood blocks – the happy medium between expense and decent support for your pool’s legs.
  • Concrete pavers – are the sturdiest of these options and provide the most support for pool legs but are also the most expensive.


Where Can You Buy it?

Your options can vary depending on what kind of pool block you are interested in buying. In general, home improvement and do-it-yourself type stores are your best bet for finding what you want to put underneath your above-ground pool legs.

You can also find some products online through retailers like Amazon or Walmart. Specialty landscaping companies can also be contacted for quotes on products like concrete pavers.

This is because they understand the need for a long-lasting, stable above-ground pool than most other vendors. They might even be able to recommend you use certain products over others they offer for the best chance at a great installation.


How Much Does it Cost?

This question, again, depends on what material you are looking to put under your pool legs.

Although relying on foam tiles for support underneath a pool leg isn’t recommended, you can find half-inch thick options that cover 144 square feet – more than enough for just your pool legs.

This option would cost you just over $100, and any excess foam tiling can also be used under the bottom of the pool.

Alternatively, a single concrete paver from some specialty vendors will cost you about $40 per paver, quickly increasing the cost when you consider how many you will need.


How Many Blocks Do You Need? 

The number of blocks you need underneath your pool legs depends mostly on the size of your pool. A larger pool will likely need more legs to be supported, so you will need more blocks.

You may also choose to double up on blocks underneath the pool legs for reasons like leveling, in which case you will also need more blocks.

If you don’t know how many legs your above-ground pool has, it’s best to order more and use less than not have enough and delay work progress as a result. On the other hand, if you order too many, you can likely find other DIY projects to use them in.


Final Thoughts on Blocks For Pool Legs

Whether you are helping source materials for a professional installation or doing the entire construction yourself, making sure that your pool legs are properly supported will help increase the usable lifespan of an above-ground pool.

Not only does the right support prevent an above-ground pool from sinking into the ground over time, but they are also long-lasting and resistant to natural hazards like weathering and pests.

It is well worth the extra expense to have a pool you and your family can enjoy for years to come rather than to cut corners and have a disappointing result.
