We were invited to build a double-sided view wall, sometimes up to 4 meters high, in which dozens of companies participated. We participated in the project for 10 years.
We were given a section with straits, which was the most difficult, because it contained 6 vaults. Many types of stones were used on this huge structure, such as: cornea, crystalline slate, basalt, crustacean sandstone, granite, etc. Work was done both indoors and outdoors.
This building was used outdoors even at a temperature of -18 ° C (hot air insulation was used).
