You’ve determined to join the ranks of fiberglass pools and installation proprietors. You’re probably picturing yourself as a bronzed god or goddess, gliding thru crystalline water at the same time as the heady scent of jasmine wafts via the air. The fact are you’re approximately to have a huge hole to your yard, a crane blocking off your street and a decision to make about gravel so that it will haunt your desires. Welcome to the arena of preformed pool set up.
Before that bright fiberglass pools installation shell arrives on a truck, searching like a large bath that escaped from a spaceship, there are things you need to recognize. Let’s dive in (pun fully meant).
It’s Not Just a Hole, It’s an Emotional Journey
First, allows speak approximately the excavation phase. You may suppose digging a hole is easy. It is not. This is wherein grown adults can be seen weeping into their morning coffee.
The method starts with something called a "dig sheet." This is not a bed sheet you are taking on a picnic. It’s a detailed blueprint that tells the excavation team exactly a way to dig. When the team of fiberglass pools and installation arrives, they'll spend hours staring at the ground, then at a chunk of paper, then back on the floor, muttering things like, “We’re off by using two inches on the south wall.”
The Great Gravel Debate
Here’s something nobody tells you: the success of your entire pool rests on crushed stone. Not sand. Never sand. Sand is for beaches and sandboxes, not for supporting a multi-ton fiberglass pools and installation project.
Professional installers use clean angular gravel usually ¾ inch crushed stone. It interlocks like nature’s Lego bricks, providing drainage and stability. If someone suggests using sand or native soil for backfilling, politely thank them for their input and then never let them near your yard again.
I watched an installation once where the crew spent four hours screening the gravel base. Screening involves dragging a long board across the gravel to make it perfectly smooth and level. They checked it with lasers. Lasers! For a hole that’s about to be filled with water and covered by a giant fiberglass shell but that’s the level of precision we’re talking about.
The Day the Crane Comes
The delivery day arrives with all the drama of a movie premiere. A flatbed truck appears, carrying your preformed fiberglass pool like a precious artifact. Then come to the crane or sometimes a massive excavator with straps.
And the frightening thing about this is the following: they carry this 900 kilogram shell on their shoulders up. Yes vertically. It is suspended in the air spinning slightly about in the wind as your neighbors stand there with their phones at the ready to put the imminent catastrophe on Face book. It is led down by the crew using ropes and instructions are shouted "Left! No, YOU'RE left! NING Stop, Pushing it" and, softly crushing its way, it sunk upon the gravel undercarriage. You will find that your bank account is relieved and this sighs.
The Water-Backfill Tango
Now comes the part that separates the pros from the amateurs: the simultaneous fill and backfill. This is a delicate dance.
You need to fill the pool with water and backfill around it at the equal time. The water level and the gravel level have to live inside 12 inches of each different always. If you mess this up, the hydrostatic strain can buckle the partitions. Imagine a soda can crumble inward. That’s your pool.
The crew will be inside the empty shell, walking around in their sock feet to feel for soft spots where the base might have shifted. Your feet can tell you things your eyes cannot—a slight give under the arch means there’s a void underneath that needs attention before it becomes a problem.
The Plumbing Reality Check
At some point, someone has to cut holes in your beautiful new shell for skimmers and returns. This is not a DIY moment for the faint hearted.
Fiberglass pools and installation require precise cuts unlike vinyl pools where you can hide mistakes; a misplaced hole in fiberglass is there forever. It’s the tattoo you regret at 3 A.M.
The plumbing itself should be rigid PVC. Some cowboys use flex pipe to save time, claiming they can do "one-day installations." These are the same people who will be long gone when you’re plumbing shifts and cracks two years later. Real fiberglass pools and installation takes time. It takes about two to four weeks from start to finish and long enough to build anticipation and short enough that you won't forget why you started this madness.
Hydrostatic Valves- The Unsung Heroes
Nobody talks approximately hydrostatic comfort valves at cocktail events but in case you stay in an area with a high water table, those little gadgets are the most effective aspect standing among you and a pool that pops out of the ground like a jack-in-the-box throughout heavy rain.
These valves are installed in the important drain. If groundwater pressure builds up below the pool, the valve opens, allowing water to go into the pool and equalize the pressure. Without it, your pool ought to literally flow proper out of the ground.
Imagine coming home from vacation to find your swimming pool sitting two feet higher than you left it, like it tried to make a run for freedom .
The Finish Line
After the backfilling is done, the coping installed, and the deck poured, you finally get to fill it completely. The first time water flows from the hose, you’ll stand there watching it rise for hours. You’ll notice how the light plays across the gel coat surface. You’ll run your hand along the smooth, non-porous surface that will resist algae far better than concrete ever could.
Will there be moments during installation when you question your sanity? Absolutely when the excavator hits a rock the size of a small car, or when it rains for three straight days, you’ll wonder why you didn’t just join a community pool.
But then summer comes. The water warms quickly because fiberglass absorbs heat efficiently. The maintenance is minimal and when you float on your back staring at the sky listening to the gentle hum of the filtration system moving water through the skimmer box, you’ll forget all about the gravel debates and the laser levels.
You’ll just know it was worth it. Even if you still can't look at sand the same way again.
