Underwater Operations
No longer are pool owners kept out of the water for up to a week to complete a repair that includes a day of draining, repair time and 1 1/2 days of water refill. Swimming can resume minutes after an "Underwater Operation" repair and owners can avoid a sizable increase in their water bill and chemical start-up.

In addition, there is no risk of plaster expansion in the dry Arizona climate, which can crack and further damage an empty, exposed pool. John Melder owner of Underwater Operations states, With our unique patented product, I can complete the average repair in just a few hours. When I jump out of the water, pool owners and their families can jump right back in.
Services
We restore pools marred with unsightly rebar rust spots, cracks and many other pool surface issues in just hours - not days - all underwater! Swimming pools are a common outdoor living feature in Arizona. While it's great to spend a scorching afternoon in your very own pool, the thought of swimming pool repair gives many homeowners pause.
Swimming pool repairs can seem like a headache, but at Underwater Operations, our goal is to take the stress out of having your pool fixed. We offer a variety of repairs that can be done without draining your pool. This saves you time, energy and money, and can allow you to get your pool serviced sooner, rather than later.
Do you have rusty stains in your concrete pool? It's likely coming from the steel reinforcing bar, often called the rebar, that is inches below the surface of the concrete. As time goes by and the bar gets rusty, the rust can leach out onto the concrete, causing an unsightly underwater rust stain. Normally, pool rebar repair entails draining the pool and cutting out the offending portion of rebar before replacing it and the concrete.
The ground is always shifting slightly, and over time, these undetectable movements can cause some cracking in your pool. Traditional crack repair techniques require that the pool be drained, which can actually exacerbate the problem. Cracks can spread or new cracks can occur, and the hot Arizona sun can wreak havoc on your pool's finish.
Have you noticed plaster pops, separation or bubbling in the layers of your pool's surface? This is called delamination, and it can occur for a wide range of reasons. It could be that oil or dirt got in between the layers of your pool when it was being built, or maybe your plaster swimming pool was drained for a repair on a hot day.
