Located in South Beach Miami, the Capri Residences include 72 luxury condominiums right on Biscayne Bay with breathtaking downtown city and water views. The development also features oversized balconies, a lap pool, waterfront gym, private roof top terraces, on-site boat slips and underground parking.
The location, on the edge of Biscayne Bay, posed concerns for waterproofing protection from the high hydrostatic saltwater pressure, especially for the underground parking facility below the building that extends 10 feet (3.05m) below sea level. In addition, a retaining wall was poured to support the 14-floor structure and hold back the headwaters of the Bay. A 4-foot (1.22m) thick Tremie slab was poured underwater and then subsequently pumped dry to create a “bathtub.” The slab was later topped by a 4-foot thick (1.22m) structural slab. As pouring such a large volume of concrete at one time at such thicknesses would almost guarantee the formation of cracks in the concrete, PENETRON ADMIX was used to ensure a watertight structure. PENETRON experts worked closely with the concrete supplier by reviewing mix designs and dosage rates at their plant to ensure that the more than 7,000 cubic yard (5,352m3) concrete pour went smoothly.
