Why I Use a Tarp Under My Pool
When I first set up my pool, I quickly realized that placing a tarp underneath was absolutely necessary. The ground beneath can have sharp rocks, sticks, or debris that could easily puncture or damage the pool liner. By laying down a tarp, I create a protective barrier that helps extend the life of my pool and prevents leaks.
Another reason I rely on a tarp is for added cleanliness. It keeps dirt and grass from sticking to the bottom of the pool, making maintenance much easier. Plus, the tarp provides a smoother surface, so the pool feels more comfortable to walk or sit on.
Overall, using a tarp under my pool has saved me time, money, and hassle. It’s a simple step that makes a big difference in protecting my investment and enjoying my pool worry-free.
My Buying Guides on Tarp For Under Pool
When I first decided to set up a pool in my backyard, I quickly realized how important it was to have a good tarp for under the pool. Choosing the right tarp can protect my pool’s bottom, extend its life, and make maintenance easier. Here’s what I learned through my experience and what I recommend you consider before buying one.
Why Do You Need a Tarp for Under Your Pool?
From my experience, a tarp acts as a protective barrier between the pool and the ground. It prevents sharp objects like rocks, sticks, or roots from puncturing the pool liner. It also helps keep the bottom clean and reduces wear and tear caused by friction.
Material Quality and Durability
I looked for tarps made from heavy-duty polyethylene or woven polypropylene because they are waterproof, resistant to tearing, and durable against UV rays. A tarp that is too thin or cheaply made won’t last long and might cause more harm than good. I recommend checking the material weight (measured in mils or GSM) to ensure it’s sturdy enough for your pool size.
Size and Shape
One of the first things I did was measure the exact diameter or dimensions of my pool. The tarp should be slightly larger than the pool to allow for proper coverage and folding under the edges. If you have a round pool, make sure to get a round tarp; for rectangular or oval pools, get a tarp that matches those dimensions. Some tarps come in universal shapes but double-check that they fit your pool properly.
Waterproof and UV Resistance
Since the tarp will be exposed to water and sunlight constantly, I prioritized tarps with waterproof coatings and UV resistance. This prevents the tarp from degrading quickly and keeps it from absorbing water, which could cause mold or mildew buildup.
Ease of Installation and Maintenance
I appreciated tarps that were lightweight and easy to spread out under the pool without wrinkles or folds. Some tarps have grommets or reinforced edges for securing them in place, which helps keep them from shifting. Also, I chose a tarp that was easy to clean—just a quick rinse with a hose to remove dirt and debris.
Price vs. Value
While it’s tempting to go for the cheapest tarp, I found that investing a bit more upfront saved me money in the long run by protecting my pool liner better. Look for a balance between cost and quality. Reading customer reviews helped me find a tarp that offered great durability without breaking the bank.
Additional Features to Consider
- Anti-slip texture: Some tarps have a textured surface to prevent slipping when walking around the pool.
- Mildew resistance: A treated tarp can resist mold and mildew growth, especially in humid climates.
- Color options: Lighter colors reflect heat and may keep the pool area cooler, while darker colors may absorb heat.
Final Thoughts
Choosing the right tarp for under your pool made a huge difference for me in terms of protection and maintenance. By focusing on material quality, size, and durability, you can ensure your pool stays in great shape season after season. I hope my guide helps you pick the perfect tarp to enjoy your pool worry-free!
