ABOVE-GROUND POOLS

Above-ground pools are the cheapest construction option, as well as the easiest to build. Most above-ground pools are made from prefabricated kits, which even an amateur can put together (though most people go with professional installers). First, the installers level off the ground to form a flat building surface. Then they assemble a perimeter track, which supports the outer wall (made of metal, plastic or wood). Next, they spread sand in the pool area and lay the plumbing. Finally, they secure the vinyl liner over the pool walls, fill the pool with water, smooth the liner and fasten it into place. As soon as they hook up the pump and filtering system, the pool is ready to go. The main disadvantage of this sort of pool is that it’s less durable than other designs, and generally less attractive. It’s also less permanent, which can be a good thing — it’s relatively easy to disassemble the pool and move it to a new location.
