PENETRON in Sao Paulo Metro, Brazil


The global sporting events in Brazil include the Confederations Cup (a World Cup warm-up tournament) held this summer, the FIFA World Cup in 2014 and the 2016 Summer Olympics. As Brazil’s largest city, São Paulo has embarked on comprehensive upgrades to the public transportation system to manage the expected surge in tourism to the city.

The Metropolitano de São Paulo (commonly called Metrô) is the main rapid-transit system in São Paulo and the largest in Brazil. The recently added Line 4 is 12.8km long with 11 stations along the entire route. It is expected to serve close to one million users every day – even before the sporting events come to town.

Working with Odebrecht, Camargo Correa, Andrade Gutierrez, OAS and Queiróz Galvão, contractors and well-known civil works engineers, PENETRON ADMIX was approved after numerous compatibility, durability and performance tests. PENETRON ADMIX helped increase resistance to water penetration and improve concrete durability of all 11 of the Line 4 underground stations.

The performance of PENETRON ADMIX as a PRAH was a key factor in its specification. Moreover, including PENETRON ADMIX in the ready-mix concrete gave the construction team a scheduling advantage.
