To improve the concrete's properties, ice was added to its composition, which allowed for temperature control and prevented negative consequences associated with high ambient temperatures.

Burj Khalifa Foundation: 50-Meter Boreholes and Innovative Polymer Resin

Before construction began on the Burj Khalifa in the United Arab Emirates, engineers faced unique geological conditions. The rock at the construction site was not only brittle but also cracked, a common problem in the region. These factors complicated the foundation stabilization process, which differs from standard methods used for most skyscrapers worldwide. Solving this problem required an innovative approach and the use of modern technologies, which ultimately contributed to the successful completion of one of the tallest buildings in the world.

To solve this problem, 50-meter boreholes were drilled, but the fragility of the rock and the presence of groundwater created a risk of collapse. To prevent this, the boreholes were filled with a special polymer resin, which displaced the water and provided strength by holding the rock fragments. Concrete was then poured into the boreholes, displacing the resin and, upon hardening, forming strong foundation piles. This approach ensures the reliability and durability of the structure, preventing possible deformation and collapse.

The foundation of the Burj Khalifa is a monolithic slab approximately 4 meters thick, which rests on 200 piles with a diameter of 1.5 meters. This design ensures the building's high reliability and resistance to various natural and artificial influences. Such engineering solutions have become key factors in the success of the Burj Khalifa as one of the tallest buildings in the world. A stable foundation plays a vital role in ensuring the durability and safety of a skyscraper, making it an outstanding example of modern construction art and engineering.
