Shotcrete is a technique where the concrete mixture is applied to the surface with the help of high pressure and special equipment. The installation can be done through dry and wet mix method. This technique is flexible and has a fast way of installation, but requires good mechanization as well as specialized and well-trained workers. It can be used alone, or in combination with anchors, steel mesh, fiber or other. Shotcreting is widely used in construction especially in: tunnel construction; construction of hydro-technical facilities; slope protection; protection of construction pits; mining; airfields; reconstruction of various buildings, and others. Evidence of the mass and increased application of this technique can be seen in the figures. Thus, in 2019, 4.881 billion dollars were spent, and it is predicted that in 2023 this figure will be around 11.5 billion dollars. The biggest consumers of the sprayed concrete technique are the Europeans, but also the built-in quantities in Asian and other countries are not negligible. While in our country this technique is almost new, and it is mostly used in the protection of: slopes in road infrastructure, tunnel construction, hydraulic structures, and similar. There are several examples, but with the announced infrastructure projects it is obvious that this technique will certainly be installed in much larger quantities.
