C.E.S. Office – Martinez House: Gunite all-concrete building

Walls, columns, beams, ceilings, all made by gunite shot on a light weight and low cost guidework of lightweight wooden frame. Gunite is a high-strength concrete made of sharp sand and concrete, carried in air under high pressure, shot dry from a hose, with water added through fine holes at he last minute before the material leaves the hose. Gunite does not require formwork, as poured concrete; instead it is shot against a guide-work, made easily and cheaply. The technique of gunite forms beautiful and complex shapes with cheap, lightweigh guide-work made of foam, masonite, and light-weigth cheap wood, one-by-twos, one-fours, and so on.
