Nikolayevsky Dry Dock

Nikolayevsky, Russia

Description

Used for the construction, maintenance, and repair of both commercial and naval ships, the Nikolayevsky Dry Dock was inaugurated in 1891 by Tsar Nikolas. A typical dry dock is essentially a narrow concrete basin with an overflow dam and is open on one end, where it can be closed by gates. The Nikolayevsky Dry Dock, over 100-years old, recently underwent a multi-year renovation to repair concrete elements damaged by exposure to seawater (and chloride ions) responsible for corrosion in the dry dock’s concrete elements.


Products Used

The most recent renovation project involved all concrete structures of the basin, the overflow dam, and the gates. Work began with the basin; the large granite blocks were dismantled, the underlying structure was cleaned and then filled with new concrete treated with PENETRON ADMIX. The crystalline admixture was also added to all new concrete for the overflow dam and the gates to provide permanent resistance to any further chloride penetration from the seawater.
