The Cidade Matarazzo is a newly renovated historic complex of 10 buildings in the center of São Paulo, Brazil. The $472 million (almost 3 billion reals) Rosewood São Paulo project covers 30,000 m2 and offers 160 guestrooms, 100 Rosewood Residences housed in the restored Matarazzo Maternity building (first built in 1943) and a new 15-floor Mata Atlântica Tower designed by Pritzker Prize-winning architect, Jean Nouvel. In addition, the complex comprises the Chapel of Santa Luzia, newly restored to its original 1922 state and open for weddings and other events, a culture center, a fashion retail center, and 34 gastronomy sites, including a rooftop pool and bar with views of the city. Further amenities include two swimming pools, a cinema, music studio, event space, and a wellness spa. In addition, an extensive art collection with more than 450 works by 57 contemporary Brazilian artists decorates the interior and verdant gardens.
Easily mixed in during batching, PENETRON ADMIX was used to treat the concrete for the foundation slabs and retaining walls during the second phase of construction, now ongoing. PENETRON, a topical crystalline waterproofing material, and PENECRETE MORTAR, a crystalline waterproofing repair grout, were used in combination to repair and waterproof the existing concrete structures of the Matarazzo Maternity and other historic buildings. PENEBAR SW, a swellable waterstop, was applied to seal the construction joints of the below-grade structures.
