Hide and Seep
A Flood Cut is a term used in water remediation and construction used to describe the partial removal of drywall up to a certain height. The obvious purpose is to allow the removal of water damaged drywall, insulation and other building materials and allow access to framing and salvageable materials for drying.
Wet insulation can have an adverse effect on the entire structure of your building. Trapped in moisture can penetrate through the ceiling, walls, and other areas, thereby cracking and rotting the surfaces, and eventually collapsing the whole structure. So the flood cut is important to insure everything gets dried out properly.
