Housed in the old Arts and Crafts School building that was designed and built at the end of the 19th century, the building underwent a comprehensive redesign, expansion, and renovation in the 1990s by architect Paulo Mendes da Rocha. However, over the ensuing decades, leaks in the building’s roof and gutters, and hydrostatic pressure from the site’s groundwater resulted in widespread water damage to the concrete walls and basement structures.
The US$ 425 million project comprised a complete overhaul of the below-grade concrete structures, including the foundation slab, retaining walls, and key above-grade elements exposed to the environment. PENETRON ADMIX was specified for all new below-grade concrete structures. Repair work throughout the museum included application of PENECRETE MORTAR, a crystalline repair grout, to fill cracks, and a topical application of PENETRON, a cementitious crystalline waterproofing material, completed the treatment.
