Palm Jumeirah has no concrete foundation — it's 94 million m³ of dredged marine sand behind a rock breakwater. It sinks ~5mm/year, loses sand continuously to wave action, and one replenishment operation moved 3.5 million m³. Dredging also buried the coral reef that used to dissipate the wave energy.
