Territoria Apoquindo Office Towers, Las Condes (Santiago), Chile

Until the 1930s, the city of Las Condes was little more than a rural backwater east of the capital. Today, as part of the Santiago metropolitan area, it is an affluent city with a booming business sector. Featuring a mix of elegant residential neighborhoods and towering business centers, most of Las Condes′ commercial activity is situated along Apoquindo Avenue, which is often referred to as "Sanhattan."
The Territoria Apoquindo Office Towers at Apoquindo 5400 were designed by De Iruarrizaga & Leterier Arquitectos, a well-known Chilean architectural team responsible for numerous high-profile projects across the greater Santiago area. The three office towers of the Territoria Apoquindo project are each 20 stories tall and comprise a total of 35,000 m2 of floor space. The top of each tower features a landscaped roof garden while the ground floor areas and the central plaza feature park-like green spaces and extensive retail areas for shopping and entertainment.
The six underground levels that form the Territoria Apoquindo tower foundations, the 1,200-car parking garage, and further basement structures, also house a large bicycle garage and a pedestrian tunnel that provides direct access to the nearby Santiago Metro subway station.
A competitive crystalline admixture was initially specified by the engineers at Territoria to secure these structures against the high groundwater at the construction site. To be on the safe side, the engineers also reached out to a local team of concrete experts about a high-performance solution that would permanently protect the extensive underground concrete structures.
The team at Penetron Chile worked out a tailor-made solution addressing all desired performance parameters of the concrete mix and further assurance was provided by the extensive track record of Penetron in similar projects in the region. This ultimately convinced the client of the unmatched Penetron performance when it comes to permeability-reducing and self-healing.
After successful testing, Society Petreos, the local ready-mix supplier, added PENETRON ADMIX to over 2,100 m3 of concrete used for the below-grade basement walls and the foundation slabs. To secure the interfaces between the walls and slabs, around 300 m of PENEBAR SW-45 ensured a permanent seal for the new concrete joints.
