Marble House Terrace Restored
More than a century of exposure to corrosive sea air and the elements had opened significant cracks in the marble pavers of the Marble House terrace. The cracks created an uneven surface and allowed water to leak through and cause even more damage to the underlying support structure.
The original brick substructures under the entire perimeter marble balustrade, wall veneers, and staircases were found to be damaged from long-term water infiltration, freeze-thaw damage, and weathering. All structural steel lintels and tie rods had also rusted through. In addition, two additional areas of the original slab above the original furnaces were found to have failed. All of these areas, comprising approximately 38% of the total terrace area, had to be strengthened with reinforced concrete, new steel lintels and tie rods and new brick masonry, and resurfaced before the new pavers could be installed. All exterior marble elements were carefully removed, numbered, stored on site and prepared for reinstallation after the needed repairs.
New sub-surface, waterproof membranes and drainage boards were installed. Surface expansion joints, the lack of which led to the failure of the original paving stones, were also installed and caulked according to professional industry standards. These improvements should increase the life span of the new terrace paving considerably over the life of the original.
Once the underlying foundation work was completed, the terrace was restored to its original appearance, using approximately 5,000 square feet of white marble paving stones specially quarried for the project in Vermont.
