Spray Foam Insulation and Coastal Flooding - Assessing flood damage
In the immediate aftermath of extreme weather situations such as hurricanes and flooding, it is necessary to assess the extent of the damage, extent of contamination, proper clean up requirements, when rebuilding/repairs can begin and flood resistance design strategies.
It is important, following extreme weather events that cause flooding, to assume that water is almost always contaminated. It may be highly likely that the incoming water contains contaminants such as:
- Dissolved salts
- Decaying organic matter and debris
- Raw sewage
- Fuel, oils and solvents
- Microbes, mold and pathogens
- And possibly various forms of marine life
Since these contaminants are moved by water under hydrostatic pressure, contamination can be seep deeply into and around porous materials, cracks and gaps. Wicking also aids the contaminants travel into areas above the actual flood level. Additionally, freezing and thawing of moist building materials can accelerate the effects of flood damage.
Whether open-cell or closed-cell, spray foam insulation is not only effective air-barrier and helps minimize heating and cooling costs, but offers additional benefits – particularly in extreme weather events. Closed-cell spray foam can be used a water-resistant barrier to help deflect moisture away, while open-cell spray foam breathes for bi-directional drying.
In upcoming blog posts, Building Genius looks at what to consider when cleaning and removing debris and moisture after extreme weather events as well as how spray foam insulation can play a role in retrofit and repair strategies. Download a complete White Paper on this topic here.
