In 1949, Soviet engineers faced a massive challenge while trying to build the main building of Moscow State University. The skyscraper was designed to be over 200 meters tall, but the ground near the Moskva River was extremely unstable and wet. Traditional concrete foundations risked sinking or sliding into the river before they could even set.
To solve this, civil engineers came up with a radical idea. They installed thousands of freezing pipes deep into the mud around the foundation site. By pumping liquid refrigerant through these pipes, they artificially froze the marshy soil into a solid block of ice.
This frozen ground acted as a temporary barrier and provided a rock solid base. Workers could safely excavate the area and pour the massive concrete foundation without soil collapse. Once the heavy structure was completely built, the ground was allowed to thaw naturally.
The finished building opened in 1953 and remained the tallest building in Europe for decades. The clever artificial freezing technique successfully prevented structural failure and is still studied by modern structural engineers today.
