| Building damage: In a few situations, deep or fast moving waters will push a building off its foundation, but this is rare and Kane County has few areas where the depths and velocities are that high. More often, structural damage is caused by the weight of standing water, known as “hydrostatic pressure.”
Basement walls and floors are particularly susceptible to damage by hydrostatic pressure. Not only is the water acting on basement walls deeper, a basement is subjected to the combined weight of water and saturated earth. In addition, water in the ground underneath a flooded building will seek its own level, resulting in uplift forces that can break a concrete basement floor.
