Swimming Pool Flashing Process

So, we're here in the North Dallas area and we've got this crazy expansive clay soil. You can see it's already cracking because it's already starting to dry out from excavation. And what happens is when any kind of moisture attracts to that, it wants to grow, it wants to expand. So, normally, the soil goes up. But in this case, the path of least resistance is to come into the pool. That presents a real problem because we've got rain coming tomorrow and we don't want this entire pool caving in. Then we would have to come muck it out, which costs thousands of dollars. So, instead, we're going to flash the pool today.

Flashing is just a thin coat of either the gunite or shotcrete that we're eventually going to build the pool shell with. But in this case, we don't have enough time to get all the rebar in, get the inspections done prior. So, what we're going to do is we're going to shoot that thin layer of shotcrete over the entire pool and on top of the soil so that any water that comes in goes down inside the pool and doesn't affect the side walls. And that should help us keep the integrity of the pool throughout the storm.

So, shotcrete starts with the shotcrete pump. And this is the biggest, baddest shotcrete pump you can buy in America. The concrete truck's going to back up here. He's going to pour the concrete in here. And just like a concrete pump, there's two pistons that push the concrete down the line. But in this case, it pushes about two to three times the pressure of a normal concrete pump that you might see on a construction site. So, this is the shotcrete nozzle and they'll go ahead and put this on the end of the hose. And while they're shooting concrete out the end, they'll mix it with air coming in the smaller hose. And you can see that the nozzleman has the ability to adjust how much air, and this is how they spray the concrete right on the wall.

About MedHawk Pools in North Texas

At MedHawk Pools, we specialize in handling the unique challenges of the North Dallas area, particularly its expansive clay soil. When building pools, we employ a method known as "pool flashing" to protect against potential soil movement due to moisture. This involves applying a thin layer of shotcrete over the pool and soil to create a water-resistant barrier. With the help of our high-powered shotcrete pump, we ensure the water drains into the pool, safeguarding the sidewalls and maintaining the pool's integrity. This technique is part of our commitment to delivering quality and durable pools across Celina, TX, and other cities including Frisco, McKinney, Gunter, Van Alstyne, and Prosper.
