On completion of the steel reinforcement being placed we apply at high      velocity, sprayed concrete, (shotcrete) to the walls and the floor to
        form the pool structure. Concrete is delivered to site in a wet mix
          to our approved design, and then is poured into the pump
           hopper. We use our Putzmeister
           concrete pump to project the
           concrete through a series of
          hoses to the nozzle.
