PENETRON - An Optimal Solution for Santiago Metro

PENETRON ADMIX-treated shotcrete was applied to ensure waterproof concrete structures for Santiago Metro’s new Line 3

Waterproofing the subway: During the initial stages of construction, PENETRON ADMIX-treated shotcrete was applied to ensure waterproof concrete structures for Santiago Metro’s new Line 3

The new Line 3 extends the Santiago Metro network by 21.7 km (13.5 miles) of track conneting 22 new station. The tunnels are station are waterproofed with PENETRON ADMIX.

One of the most modern subway networks in Latin America – and the second largest after Mexico City - the Santiago Metro currently maintains five lines with 108 stations and a total rail length of 103 km (64.0 miles). The first section of the Metro’s new Line 3 will take on its first passengers by the end of 2017. Comprising 22 stations on 21.7 km (13.5 miles) of track, the Line 3 will be completed by 2020. It will connect the northern part of Santiago (Huechuraba) with the city center and central business district and the eastern part of the city (Ñuñoa, La Reina and Peñalolén).

The technical guidelines for the Santiago Metro project originally specified a competing product. At the request of the Ferrovial Agroman Chile construction company, PENETRON Chile met with Arcadis, the project engineers and advisors to the Santiago Metro. After reviewing various studies, recent project results and learning about PENETRON crystalline technology, Arcadis selected PENETRON ADMIX as the most effective waterproofing solution for the tunnels and stations.

A key factor in PENETRON’s success was the high level of technical support under Domingo Lema. The local PENETRON team has extensive experience with mix design and shotcrete applications. They were able to show that PENETRON ADMIX was an ideal solution.

Having PENETRON crystalline technology certified for enhanced concrete durability, self-sealing of cracks and waterproofing convinced the engineers at Arcadis. Ultimately, PENETRON ADMIX was used to treat over 33,000 m3 (43,200 cubic yards) of concrete during the initial phase of construction.
