The present disclosure provides a water-blocking device including a water-blocking plate installed on a floor of a passage, rails installed on both sidewalls of the floor, and a driving part configured to lift and lower the water-blocking plate, wherein, when the driving part is operated, the water-blocking plate is lifted and lowered along the rails.

According to one example, a window system includes a window and further includes a frame that can be coupled to an opening in a structure. The frame includes one or more window seats and one or more moveable window stops. The one or more window seats can surround all or a portion of a periphery of the window. The one or more moveable window stops can be moved and coupled to different positions along a depth of the one or more window seats. The window includes a first window portion, a second window portion, and an interlayer positioned in-between the first window portion and the second window portion. The interlayer extends out of the periphery of the window.

Disclosed is an improved flexible flood barrier system for creating a watertight barrier. The system includes a novel hinged clamping bar assembly configured to engage a hem of the fabric flood barrier. The fabric flood barrier is comprised of a waterproof layer reinforced with high strength webbing straps. The webbing straps are weaved together through slots in one of the layers without the need for stitching upon any of the waterproof layers. When deployed the improved fabric flood barrier system prevents storm surges from breaching the flexible flood barrier system at the attachment points.

The present disclosure provides a water-blocking device including a water-blocking plate installed on a floor of a passage, rails installed on both sidewalls of the floor, and a driving part configured to lift and lower the water-blocking plate, wherein, when the driving part is operated, the water-blocking plate is lifted and lowered along the rails.

Apparatus for protecting the interior of a structure from flood water includes a panel which is shaped and dimensioned to cover the opening in the structure. The panel is fabricated from foam which is covered by a skin. The panel is positioned over a window or other opening of the structure and removably connected to the structure. In another embodiment, multiple panels are connected together to span a wide opening. The panel(s) can be made in different shapes and sizes to accommodate different opening configurations.

According to one embodiment, a flood vent panel includes a first area, a second area, and a first set of one or more perforations positioned on a first side of the flood vent panel in a location in-between the first area and the second area. The perforations are configured to break when at least a predetermined amount of pressure is applied to a portion of the second area. The flood vent panel is configured to be coupled, at least indirectly, to a structure so as to at least partially block a fluid passageway through an opening in the structure. The break is configured to completely separate the second area from the first area so as to reduce an amount of blockage of the fluid passageway.

The present invention relates to a retractable floodwall unit that comprises a foundation unit having a plurality of guide tracks along side walls of the foundation unit, a floodwall panel stowed in the foundation unit; a power system for raising and lowering the floodwall panel, and a plumbing system. The plumbing system is configured to remove ground water from a dry-side of the floodwall unit and flood water that becomes located in the floodwall unit.

According to one embodiment, a flood vent panel includes a plurality of insulation pieces positioned together, and a panel frame surrounding the plurality of insulation pieces. The flood vent panel is configured to be coupled to a frame positionable on a structure, so as to at least partially block a fluid passageway through an opening in the structure. Each of the plurality of insulation pieces is separate from the other insulation pieces of the plurality of insulation pieces. Each of the plurality of insulation pieces is separate from the panel frame.

The present invention is a rapidly deployable flood defense system and method that has at least one barrier cover, each comprising a plurality of laterally-extending crossbeam housing tubes stacked generally vertically and housing an inflatable crossbeam disposed within the tube, an end retaining tab at each end of the tube, and a plurality of rear support retaining tabs spaced along the lateral length of the crossbeam housing tube; and a front apron and a rear apron. The system also has a plurality of support tubes and a plurality of additional support tubes positioned along the lateral length of the crossbeam housing tube. Each support tube held in the generally vertical direction by a base post and each and additional support tube positioned along the lateral length of the crossbeam housing tube having an additional base post positioned rearwardly.

A comprehensive dry flood proofing solution to mitigate inland flooding risk for existing or new homes and small buildings. This family of integrated systems of the present disclosure each leverage the building's structure to offer practical and affordable flood protection for those buildings constructed with slab-on-grade foundations. This family of solutions includes pluggable weep holes, entry door/garage door/window protectors, wall appurtenances and penetration protection, house wrap and debris barrier system for wall protection and sewage anti-backflow protection. 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.
