The article discusses an innovative approach to the construction of a concrete surface based on the example of the completion of the A2 motorway Warsaw - Kukuryki at the section the Siedlce ring road - the "Cicibór” junction (with the junction), section VI from km approx. 561+440 to km approx. 580+190 with the "Borki” junction of the length of approximately 18,750 km, where - the JASNY CEM II/B-S 42.5 R-NA cement was used for the first time in Poland.
The article discusses the sensitive areas of snow avalanches formed in the mountain landscapes of Georgia and presents their brief geographical, climatic-meteorological and hydrological assessments. By referring to global practices, the characteristics of different constructions of snow avalanche buildings and their reliability are presented. A constructive description of an innovative snow-avalanche-proof building, certified by a Georgian patent certificate, is presented. An innovative method for the design of the building was developed and the construction of the structure was carried out in the Kobi-Gudauri alpine zone of the Georgian military road at an altitude of 2238 m above sea level.
