USAGE OF SHOTCRETE IN NORTH MACEDONIA

Shotcrete is a relatively new technique used in R. N. Macedonia. With the start of the works on the infrastructural projects throughout the territory of North Macedonia, the shotcrete became one of the most important aspect of the projects. Large quantities of sprayed concrete are installed during the construction of tunnels and protection of slopes. Tunnels on the section Demir Kapija-Smokvica and the tunnel on the highway Kicevo-Ohrid are more significant facilities to which this technique was applied. However, we should not forget about the builtin quantities of shotcrete in the landslide protection on the access road to the dam Sveta Petka, as well as when repairing the landslide on the highway Gradsko-Veles. Only in the last building, at the landslide Cucka in front of the entrance of Veles, an area of about 2,000 m² is covered with sprayed concrete.

The technique of sprayed concrete in our country does not stop here. There is a chance to become an even more trendy technique with the announced projects, or projects that are already under construction. One of the many projects that are being carried out is the expressway Prilep – Gradsko that contains the construction of a tunnel and a gallery. Apart from the construction of these elements of the building, sprayed concrete is also used in excavations in rock masses, ie protection of slopes. It is planned to install 500 m³ as the primary support of the tunnel and 20 m³ for slope protection at the gallery. It should be mentioned here that additional quantities have already been applied during the penetration of the route, ≈ 10,000m².

That is a proof that the shotcrete is a trend in our country. The predicted road and railway infrastructure projects pave the way for this technique. However, not only in the infrastructure but also sprayed concrete is expected to be used in other areas, which will further increase the amount of installation. Apart from larger quantities of sprayed concrete, the technique of this process is expected to be improved in the coming years.
