Porto Atlântico + PENETRON = Durable Concrete
The Porto Atlântico urban renewal project was a massive endeavor that relied on PENETRON crystalline technology to ensure its below-ground structures would remain impermeable. Despite the scale of the project, construction was completed in two months.
This extensive development project in the Porto Maravilha area of Rio de Janeiro is one of the city's oldest and most historic areas. After a long period of decay, the region has become a magnet for investment and new construction.
The Porto Atlântico project comprises the revitalization of two adjacent lots, 16,000 m2/172,220 square feet and 12,000 m2/129,200 square feet in size:
Porto Atlântico Leste (East Atlântico Port) lot encompasses IBIS and NOVOTEL hotels (450 rooms), two commercial towers (330 & 54 units), and 50 retail shops
Porto Atlântico Oeste (West Atlântico Port) lot includes three corporate towers with a private area of approximately 66,000 m2
This massive urban revitalization effort will boost the whole waterfront area of Rio de Janeiro, creating a new center of commercial and residential growth. Beyond construction of new buildings, the Porto Atlântico project also upgraded and modernized all infrastructures (including roads, sidewalks, utilities, sewage, and more) as part of the largest public-private partnership in Brazil to date. New building construction is LEED-certified (Leadership in Energy and Environmental Design), which confirms the sustainability criteria applied in the design during construction and in all aspects of project logistics.
All concrete basement slabs of the hotels and commercial towers were treated with PENETRON ADMIX to provide permanent protection against the high hydrostatic pressure of the groundwater. In addition, as an environmentally friendly construction material with a 0% VOC content level, PENETRON ADMIX contributed additional LEED points needed for LEED certification.
Even with a waterfront location and its high water saturation levels, PENETRON ADMIX proved to be sufficiently stable to resist water under pressure. PENETRON’s success with the Porto Atlântico project confirms just how effective PENETRON’s permeability reducing (“PRAH”) technology can be, even in extremely demanding conditions.
