The report adds to concerns that the condo building may have been unsafe for years or even decades before it came crashing down in the early morning hours of June 24.
In a separate report, Morabito Consultants analyzed the building in 2018 and found that the concrete slab underlying the pool deck was improperly laid and not allowing water to disperse.
“The failed waterproofing is causing major structural damage to the concrete structural slab below these areas,” 报告说. “Failure to replace the waterproofing in the near future will cause the extent of the concrete deterioration to expand exponentially.”
多于 20 years before that, the concrete slab, which supports the pool deck and is the ceiling of the parking garage, was already showing major structural issues.
“The scope of work will be concrete structural repair in the parking garage,” Rob Sommer, a sales manager for Western Waterproofing Company of America, wrote to the Surfside Building Department in March 1996, 根据 迈阿密先驱报. “This type of repair entails removing loose concrete overhead, treating steel rebar with rust inhibitive coating and patching back with repair mortar. Also included in the garage will be urethane foam injection in ceiling cracks.”
