Capri Properties

The location, on the edge of Biscayne Bay, raised concerns about waterproof protection against high hydrostatic salt water pressure, especially for the underground parking facility under the building, which rises 10 feet (3.05 m) below sea level. In addition, a retaining wall was cast to support the 14-story structure and to block the bay's underlying water. A 4-foot (1.22 m) thick Tremie plate was flooded and then pumped dry to create a “bathtub.” This plate was later provided with a 4 foot thick (1.22 m) structural plate. Since pouring such a large volume of concrete at the same time and with such thicknesses would almost certainly ensure 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 controlling mix designs and dosing rates at their plant to ensure that the more than 7,000 cubic yards (5,352 m3) of concrete could be poured without problems.
