When planning a backyard pool, many homeowners hear the myth that fiberglass pools can “float” or “pop” out of the ground. It’s a concern that often comes up for those considering a fiberglass pool in Knoxville, TN. While the thought sounds alarming, the reality is simple: when installed properly, fiberglass pools will not float or shift out of place.
At Foothills Outdoor Designs, we specialize in fiberglass pool installation in Knoxville, TN, and we want to put this common myth to rest. By understanding hydrostatic pressure and proper installation methods, you’ll see why fiberglass pools are a safe, reliable choice.
The myth starts with hydrostatic pressure. This pressure happens when water builds up in the ground around a pool. If the pressure outside the pool shell is greater than the pressure inside, it could, in theory, push the shell upward.
While this sounds like a real risk, it’s very rare when a fiberglass pool in Knoxville, TN is installed by experienced professionals. Correct installation methods are designed to balance these pressures and keep the pool firmly in place.
Concrete and vinyl pools are also affected by hydrostatic pressure, not just fiberglass. In fact, all pools can experience water pressure issues if they’re installed incorrectly. The difference is that fiberglass pools come with proven techniques to prevent floating, making them a secure option when done right.
One of the most important steps in installation is backfilling around the pool with gravel instead of dirt. Gravel allows groundwater to move freely rather than creating pressure pockets.
For homeowners installing a fiberglass pool in Knoxville, TN, drainage systems are also key. These systems move water away from the pool structure, preventing hydrostatic pressure from building.
Fiberglass pools are often equipped with hydrostatic relief valves. These valves automatically release water pressure under the pool when needed. It’s a smart, built-in safeguard that ensures stability, even during heavy rain or high water table conditions.
Keeping water in your pool is one of the simplest ways to prevent problems. An empty pool shell is vulnerable, while a filled fiberglass pool in Knoxville, TN balances external pressure. That’s why professional installers never leave pools drained for long periods.
East Tennessee does have occasional heavy rains, but with proper grading and drainage, your pool site can handle it. Foothills Outdoor Designs evaluates every yard before installation to make sure soil and water conditions are accounted for.
DIY installations or inexperienced contractors can lead to issues, but when you choose an expert, you’re protected. For every fiberglass pool in Knoxville, TN, Foothills Outdoor Designs uses proven methods that ensure long-lasting stability.
Beyond addressing the floating myth, fiberglass pools come with other advantages. The shells are strong, resistant to cracking, and smooth to the touch. This means fewer repairs and less maintenance over time.
Unlike concrete pools, which can take months, fiberglass pools are installed in weeks. With expert planning and drainage systems, homeowners in Knoxville, TN enjoy a fast, worry-free installation process.
The idea of a fiberglass pool “popping out of the ground” is more myth than reality. With hydrostatic relief systems, proper backfilling, and professional installation, your pool is secure. At Foothills Outdoor Designs, we take every step to ensure your fiberglass pool in Knoxville, TN is built to last.
