Next, we bring in our build crew. They will use the most efficient process possible in order to assemble your pool. The crew will fill a 1,000 gallon plastic tank as they work. This is so they can then pump that water directly into your pool. Why is this so important? It ensures that your liner is fully set before the build crew leaves your pool site. Otherwise, you might end up with wrinkles on the floor of your pool. These two separate processes insure that all of our above ground swimming pools are installed with you, the customer, in mind. Plus all of our above ground swimming pools with installation include specialty Vermiculite for under your pool. The Vermiculite is much less abrasive than sand, thereby helping to extend the life of your liner. This includes all kinds of installations, including above ground swimming pools with a deck.
