Why Above Ground Pool Underlayment Is Necessary
From my experience setting up an above ground pool, I quickly realized that underlayment is an absolute must-have. The ground beneath the pool isn’t always perfectly smooth—there are small rocks, roots, and uneven patches that can easily damage the pool liner. Using underlayment acts as a protective barrier, cushioning the liner from these rough spots and significantly extending its lifespan.
Another reason I found underlayment essential is that it helps with drainage and prevents moisture from getting trapped under the pool. Without it, water can pool beneath the liner, leading to mold, mildew, or even damage to the pool’s structure. The underlayment ensures a more stable, dry base, making the whole setup safer and more comfortable to enjoy.
Lastly, installing underlayment made the entire pool area feel more comfortable underfoot. It adds a bit of padding, which is great when kids and adults alike are walking or playing around the pool. Overall, from my personal experience, underlayment is a simple step that pays off in durability, comfort, and peace of mind.
My Buying Guides on Above Ground Pool Underlayment
When I decided to set up my above ground pool, one of the most important accessories I discovered was the underlayment. It might seem like a small detail, but choosing the right underlayment made a huge difference in protecting my pool liner and extending the life of my pool. If you’re considering getting one, here’s what I learned from my experience.
Why Underlayment Is Essential
I initially underestimated the importance of an underlayment. It acts as a protective barrier between the ground and your pool liner. This prevents sharp rocks, sticks, and rough patches from damaging the liner. Plus, it adds cushioning, which makes the pool floor more comfortable to stand on and helps prevent tears and punctures.
Types of Underlayment Materials
I found that underlayment comes in several materials, each with its pros and cons:
- Polyethylene Foam: This is lightweight and provides good cushioning. It’s easy to install but might not be as durable if your ground has a lot of sharp debris.
- Polypropylene Fabric: This type is tougher and offers excellent puncture resistance. It’s great if your yard has rough or rocky soil.
- Rubberized Mats: These provide superior protection and comfort but can be pricier and heavier to handle.
- Recycled Materials: Eco-friendly options made from recycled plastics or tires are available, offering durability and environmental benefits.
For my pool, I chose polypropylene fabric because my yard had some uneven areas with small stones.
Size and Thickness Considerations
I measured my pool’s diameter carefully to ensure the underlayment would cover the entire pool floor plus a little extra to wrap up the sides. Thickness is also key — most underlayments range from 1/8 inch to 1/4 inch. Thicker underlayments offer better protection and cushioning but might be harder to manage and more expensive. I went with a medium thickness to balance comfort and ease of installation.
Ease of Installation
I appreciated an underlayment that was lightweight and easy to handle. Some come in rolls that you can cut to size, which made installation simpler. Make sure the ground is cleared and leveled before laying down the underlayment to avoid trapping debris underneath.
Durability and Longevity
I looked for an underlayment that was resistant to mold, mildew, and UV rays since my pool gets a lot of sun. A durable material means you won’t have to replace it frequently, saving money in the long run.
Price vs. Quality
While it’s tempting to go for the cheapest option, I learned that investing a bit more in a quality underlayment pays off. It protects my pool liner better and lasts longer, which reduces the risk of costly repairs or replacements.
Additional Tips from My Experience
- Always remove sticks, rocks, and debris from the pool area before laying the underlayment.
- Consider adding a sand layer underneath for extra smoothness if your ground is very uneven.
- Check the warranty and customer reviews before purchasing—real user experiences helped me avoid inferior products.
Choosing the right above ground pool underlayment made my pool setup smoother and my swimming experience more enjoyable. I hope these insights help you pick the best underlayment for your pool!
