Should You Put Foam Under A Pool?

Many pool owners believe that adding a foam product beneath their swimming pool liners, such as Happy Foam Bottoms and Gorilla Pads, will soften the pool floor, making the bottom more comfortable to walk on while swimming. 

And in some cases, this may be so; however, there is a major problem with foam under a pool. When you put foam padding under a pool, they cause serious cleaning problems and become a headache after installation.

After installing your swimming pool liner and filling the pool with water, the pool liner gets sucked into the groves and indentations of the foam padding. This happens because the water applies pressure to the pool liner, helping it take the shape of your pool. 

As a result, whether you own a beaded style pool and liner or an overlap style pool and liner, this creates a severe cleaning problem. 

You will begin to notice the growth of algae, mold (black, green, and brown), and even fungus. Even though you may think you can just clean it with chemicals and a brush, there is a bigger problem at play. The algae, mold, and fungus becomes embedded under the pool liner between the foam paddings and the pool liner in all areas where the foam padding was installed.

Let’s not forget that this gross health hazardous fungus can spread throughout the pool liner to parts where the foam isn’t installed. 

Algae, mold, and fungus are more noticeable near foam installation areas. The only safe way to clear pools of algae and fungus is to remove the hazardous foam and install a replacement pool liner.

Don’t put your family at a health risk. Stick to the old-fashioned way and use pool sand to smooth out your base and build coves.
