We are a great believer in concrete spraying our pool shells, and not shuttering & pouring the concrete (which is a traditional method used by main contractors) as these poured pool shells can give potential weak joints between each concrete pour stage.
With our pool shells, the concrete is pressure sprayed & shot at high speed onto the reinforcing steels all at once, so the final pool is ONE PIECE only! In fact, if you had a big enough crane, you could lift the shell completely out of the ground in one complete piece.
Many clients are amazed when they see us in action spraying concrete! Here's a video of one of our spraying in action!
