handheld gunite sprayer. This
Stucco Sprayer by Nolan also sprays gunite.
Gunite, or Shotcrete as it is sometimes called, refers to the process by which concrete is pumped through a hose and is sprayed as it exits from a nozzle. This type of construction allows the concrete to follow irregular shapes and makes possible the shaping of the material as it hardens. It is the preferred technique for the shaping of swimming pools, ponds or even caves and buildings.
Nozzleman applying gunite to water tank framework.
Concrete is dumped into a pump which then delivers the material to the
nozzleman. Vertical or even overhead surfaces can be sprayed. After
material is placed and allowed to set for a while, others follow and
carve the walls, steps and other features into the hardening concrete.
