Gunite pools are the most popular design in much of the United States. To build one, the construction crew digs a hole, puts the plumbing in place and assembles a framework grid with 3/8-inch steel reinforcing rods (rebar). The rebar rods are spaced about 12 inches apart, and secured together with wire. When the grid is in place, one of our crews spray a heavy coating of gunite, a mixture of cement and sand, around the rebar. The sprayer unit combines dry gunite mix with water just before spraying -- this produces the wet concrete material. The crew then cuts walls, steps, spas, ect. to shape and then trowels the gunite smooth . Gunite pools are highly durable, and they can be built in any shape or size.

Since the material moves at a high rate of speed as it comes out of the hose, the trickle of water that is mixed with the dry mix doesn't even slow it down. Resulting in a higher PSI application, packing material tighter than Shotcrete can. Since you can make this material as dry as you want, you can achieve the strongest known form of concrete. This requires a highly skilled nozzleman, especially in the case of thick or heavily reinforced sections.
