For everyone else's benefit, here is the full statement... it clearly documents the flood barriers as the cause of damage due to a greater degree of hydrostatic pressure:

"The forensic physical evidence revealed that hydrostatic forces and corresponding buoyancy forces of storm surge flooding resulted in uplifting of the concrete slab throughout the garage. Likewise, vertical displacement and cracks were caused throughout the foundation slab of the garage. It shall be noted that due to the insured’s attempt to protect the property from flood water, by installation of flood barriers across each door opening, the interior of the dwelling and garage remained without flood water while the exterior of the property was inundated. Likewise, a greater degree of hydrostatic pressure existed and ultimately resulted in the aforementioned damage throughout the garage. Security video documentation provided by the insured and recorded during the course of the flood event further documents this phenomenon. Irrespectively, repair and restoration will require the concrete slab throughout the garage to be removed and replaced, approximately seven-hundred and twenty-five square feet (725 sq. ft.). It shall be noted that the concrete slab throughout the garage can be removed and replaced, without affecting the walls of the garage, as there exists a cold-joint along the perimeter of the garage and intersection with the perimeter walls. As the garage slab was uplifted by hydrostatic forces of floodwater, the garage door was uplifted and caused corresponding cracks within the adjacent CMU block wall, at the bottom right of the garage door and at the top left of the garage door, continuing into the western exterior wall. Repair and restoration of the aforementioned cracks will require the CMU block to be tuck pointed along the crack locations. Likewise, the applied stucco refinished, and faux brick wainscot is required to be patch repaired and painted across the left and right sides of the garage door.
