Floodwater and Building Materials
Outdoor Floodwater Can Affect More Than the Floor
Floodwater entering from outside may
carry mud, debris, chemicals, sewage,
or other contaminants. Therefore,
cleanup decisions should consider
both the moisture and what the water
contacted inside the home.
For instance, even shallow flooding
can reach baseboards, drywall,
flooring layers, cabinets, and
insulation. Meanwhile, moisture
may travel into concealed spaces
beyond the visible waterline.
As a result, a room may require
material evaluation even after
workers remove standing water.
The cleanup plan should explain
which materials can remain,
which require cleaning, and
whether removal is necessary.
Floodwater is not automatically clean water.
The source and contamination
conditions affect cleanup decisions.
