Application of shotcrete from a the nozzle to the wall. As you can see the wall of the building is being finished behind the shotcrete to create a smooth final product
Shotcrete is not inherently sticky, it likes to sag or fall away from walls which is why proper floor protection is needed in the case of interior work, it is built up from the ground and layered to reach the top of the surface.
Displayed is the reinforcement and bucking to protect sensitive structures. This is what forms the interior of any of the shotcrete walls.
Dedication to the Craft
The building had a crawl space that needed structural shotcrete adhered to the walls, our Nozzleman, Frank Espinosa, squeezed into the crawl to ensure he got the proper angles to make the perfect shotcrete wall
This depitcts the process better than any other, as the walls are being shot the nozzle-man must have someone guiding the hoze an emergency cut off switch operator and someone mucking the waste to protect the flooring.
