Yes, you absolutely need a pool liner pad for your above ground pool. A quality liner pad is one of the most important investments you can make when setting up your pool, as it protects your liner from punctures, provides cushioning underfoot, and can extend your liner's life from 3-5 years to 8-12 years or more.
Above ground pool liners are typically only 20-28 mil thick (about the thickness of a heavy garbage bag), making them vulnerable to damage from rocks, roots, insects, and ground irregularities. Without proper protection, even the smallest pebble or twig can cause a costly puncture that leads to water loss and expensive repairs.
The pad serves multiple critical functions beyond just puncture protection. It provides thermal insulation that helps maintain water temperature, creates a more comfortable walking surface, and acts as a barrier against ground moisture that can cause premature liner deterioration.
Closed-cell foam pads are the gold standard for liner protection. Products like Armor Shield or Pool Pal foam pads offer superior cushioning and puncture resistance. These pads typically come in 1/8-inch to 1/4-inch thickness and provide excellent insulation properties. They're more expensive initially but offer the best long-term protection.
Pool felt pads are a more budget-friendly option made from recycled materials. While not as durable as foam, they still provide adequate protection for most installations. They work particularly well when combined with sand base preparation.
Some pool owners consider alternatives like old carpet padding, newspaper, or cardboard. Avoid these materials as they can decompose, attract insects, or contain chemicals that may damage your liner over time.
Before installing any pad, ensure your ground is properly leveled and cleared of debris. Remove all rocks, sticks, roots, and sharp objects within the pool area plus an additional 1-foot perimeter. Fill any low spots with mason sand and compact thoroughly.
Your liner pad should extend slightly beyond your pool's footprint. For a round pool, choose a pad that's 6-12 inches larger in diameter than your pool. For oval pools, add 1 foot to both length and width measurements.
If using multiple pieces, overlap seams by at least 6 inches and tape with duct tape or special pool pad tape. Ensure all seams are smooth with no raised edges that could create pressure points on your liner.
While a quality liner pad may cost $200-600 depending on your pool size, consider that a replacement liner typically costs $300-800 plus installation labor. The pad essentially pays for itself by preventing just one puncture repair, which can cost $200-400 when you factor in water loss, chemicals, and potential professional repair fees.
The only scenarios where you might consider forgoing a liner pad are temporary installations lasting less than one season, or if you're installing over a perfect concrete slab. However, even with concrete, a thin pad provides comfort and thermal benefits that most pool owners appreciate.
Quality liner pads can last 15-20 years or more with proper installation. They require no maintenance once installed and will likely outlast multiple liner replacements. This makes them one of the most cost-effective pool accessories you can purchase.
Installing a liner pad is typically a DIY-friendly project that can be completed in 2-4 hours. However, if you're having your entire pool professionally installed, including the pad in the installation package often costs less than purchasing and installing it separately.
Bottom line: A pool liner pad is not just recommended—it's essential for protecting your investment and ensuring years of trouble-free pool enjoyment. The relatively small upfront cost prevents much larger expenses down the road and significantly improves your pool experience.
