The components of the solution are reusable, easy to deploy, and do not detract from the building's permanent appearance. Furthermore, the solution allows for ingress/egress during flood events and can protect the building from standing water incursion up to 24″ above slab elevation. The pre-flood design and preparation, the deployment immediately preceding flooding event and the subsequent removal after flooding event has passed is provided by both contractors and homeowners.
