Located in a repurposed cold-storage warehouse, AquaRio – Aquário Marinho do Rio de Janeiro – occupies 22,000 square meters (236,800 square feet) spread over five floors and a basement. It is the largest marine aquarium in South America (4.5 million liters / 1.19 million gallons of salt water). Its 28 tanks, spanning two stories, provide a home to 8,000 creatures from 350 different species. In the largest tank you can dive with fish, sharks, sea turtles and stingrays.
In order to enhance resistance to chloride penetration (from the saltwater) and increase the durability of the water tanks, all concrete used in the tank structures was treated with 3,200 kg of PENETRON ADMIX. The construction joints in the new concrete were permanently sealed with 500 m of PENEBAR SW-55 waterstop.
