You've probably pictured it already: water sheeting quietly over stone into your pool, turning a swim into something closer to a retreat. That's what a well-designed waterfall adds to a backyard pool, and it's also why pool waterfall installation in Farmingdale, NY gets planned wrong more often than any other pool add-on. The Platinum Group designs and builds custom gunite pools and water features across Long Island, and the waterfalls that still look and sound right five years in are engineered around your specific pool, not bolted on as an afterthought.
