According to Wikipedia, the gunite technique is a construction system that consists of projecting concrete with a “gun” or high-pressure hose. It can be built on any type of surface, including soil, with the aim of achieving a continuous wall, with greater resistance and less thickness, to support and contain the pressure exerted by the ground, with any type of slope, offering optimum waterproofing thanks to its low porosity.
In some countries this technique is also known as spraying, which can also consist of spraying mortar (without the coarse aggregate). In English, it is known as build-up: gunning in layers (or spraying in layers), application of shotcrete sprayed in successive layers to form a thicker mass (build-up is also the residual accumulation of hardened concrete inside a mixer or concrete mixer).
One of the advantages of this technique is the greater resistance per square meter, i.e. with less material, greater resistance and durability are achieved. It also results in the firmness of the structure that is projected by shotcrete when obtaining a compact and solid layer. This technique can be used to cover ravines and prevent risks of possible landslides, with a degree of durability that makes its maintenance small.
Gunning has revolutionized the world of swimming pool construction, since it adds to total waterproofing, an optimum water tightness of the pool vessel as there are fewer pores on the pool walls. Thanks to the versatility of this technique, original design swimming pools can be built even with complicated shapes for traditional techniques, with optimum finishes.
The development of this technique has given rise to a new form of applying continuous coatings to buildings, leading to the appearance of a new range of mortars with specific characteristics to facilitate the design, normally known as single-layer mortars, although not all single-layer mortars are suitable for design purposes, nor are all projectable mortars designed to finish off the coating with a single layer. Specific mortars for single-layer projection usually contain synthetic components in their dosage.
