Underground parking garage anti-float design

Quick answer：

Underground parking garage anti-float design refers to the structural and engineering measures taken to prevent the parking garage from floating due to buoyancy caused by groundwater or other fluids. This typically involves the use of heavy fill materials, such as compacted earth or concrete, to counteract the buoyant forces. The design also considers factors like soil conditions, groundwater levels, and structural stability to ensure the safety and integrity of the parking garage.
