Construction on the Xi’an utility tunnel project is ongoing. With estimated total costs of US$2.6 billion, it is currently China’s single largest infrastructure project. The planned 145.5-km (90-miles) of tunnel encompasses a main tunnel and numerous branch tunnels that connect the capital city with the adjacent Lantian and Huyi counties and the Yanliang and Lintong districts.
PENETRON ADMIX was used for the concrete structure of the three bottom tunnels exposed to the constant – and fluctuating – hydrostatic pressure deep underground. Not only did PENETRON ADMIX crystalline admixture meet the Level I waterproofing grade and 100-year durability standards, the Kunming Road section was also completed before the allotted deadline, thanks to a much simpler construction method when compared to the installation process for a membrane solution.
