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 Kevlar straps. The Kevlar 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.

1. A flood barrier system comprising a PVC (polyvinyl chloride) coated polyester waterproof membrane having a perimeter formed by an upper edge, a bottom edge, a left side edge and a right side edge further defining a front surface and a rear surface; a plurality of PVC coated polyester strips spaced apart and heat welded to said front surface of said membrane, each said polyester strip including a plurality of spaced apart predetermined slots; a plurality of horizontal straps extending from said left side edge to said right side edge woven through said predetermined slots formed in said spaced apart strips; a plurality of vertical straps extending from said upper edge to said bottom edge woven through said predetermined slots formed in said spaced apart strips; a hem formed along said perimeter, said hem having a rope extending along each edge of said membrane with said membrane wrapped around said rope with a plurality of notches for receipt of strap ends which are passed through each notch and looped around said rope and returned through each said notch, said strap stitched to itself to create closure and said membrane is heat welded to itself around said notch to create a waterproof seal; and a clamp bar assembly for securing said hem, said clamp bar assembly having a top surface, a bottom surface, a first side and a second side with a recessed shelf extending along a longitudinal axis adjacent to said first side surface with an annular groove disposed at a predetermined depth below said recessed shelf, said clamp bar comprised of a plurality of pressing blocks connected with a plurality of hinge assemblies for securing said hem in said annular groove; wherein said membrane secured by said hem within said clamp bar assembly prevents the passage of water through an opening.

2. The flood barrier system according to claim 1 wherein said straps are Kevlar.

3. The flood barrier system according to claim 1 wherein said vertically positioned straps include an upper end securable to a fastener placed along a top of an opening.

4. The flood barrier system according to claim 1 wherein said strips include horizontally disposed parallel slots that are spaced apart a distance to allow for vertical straps to be woven therethrough.

5. The flood barrier system according to claim 4 wherein said strips include vertically disposed parallel slots that are spaced apart a distance to allow for horizontal straps to be woven therethrough, said vertical straps further woven through said horizontal straps.

6. The flood barrier system according to claim 1 wherein each said hinge assembly includes a block having an aperture constructed and arranged to cooperate with a fastener for fixedly attaching upon said a hem within said recessed shelf, each said block having an aperture constructed and arranged to receive at least one guide shaft for rotation of said block.

7. The flood barrier system according to claim 6 wherein each said block has a protrusion that extends below said recessed shelf into said annular groove, said protrusion and said annular groove constructed of a predetermined size and shape for deforming said hem into a watertight seal.

8. The flood barrier system according to claim 6 wherein said blocks are secured along said recessed shelf by a plurality of fasteners that extend through said clamping blocks and said recessed shelf for securing said blocks in place.

9. The flood barrier system according to claim 1 wherein said block is a hinge assembly block having a top surface, a bottom surface and opposing side surfaces with an aperture that extends from the top surface through the bottom surface, said opposing side surface have a channel configured at a predetermined curvature depth wherein said hinge assembly blocks is constructed and arranged to rotate and engage each pressing bar at different angles along the channels to allow rotation of pressing bars at variable angles.
