Additionally, the rivet washer includes a membrane with at least one raised high pressure point skirt or rib and at least one recessed trough that provides a continuous seal over the outer surface of the washer body, the rivet body, and the mandrel head, and is sealably and continuously connected to the perimeter of the washer body and optionally a circumferential portion of the outer surface. ## Claims ### Claim 1 A blind rivet washer, comprising: a washer body with an outer surface including a circumferential portion of the washer body, an inner surface in contact with a substrate, and a rivet aperture through which a mandrel end of a blind rivet is insertable prior to the blind rivet being set; and a watertight or airtight membrane encapsulating completely the outer surface of the washer body and one side of the rivet aperture, wherein the watertight or airtight membrane creates a lumen which provides a space between a portion of the outer surface of the washer body and the watertight or airtight membrane into which the mandrel end of the blind rivet is insertable and encapsulated. ### Claim 2 (depends on 1) The blind rivet washer of claim 1, wherein the watertight or airtight membrane is sealably watertight or airtight connected to a perimeter of the washer body, and optionally a circumferential portion of the outer surface, by a fixing means to form a single blind rivet washer assembly which the mandrel end of the rivet is insertable. ### Claim 3 (depends on 2) The blind rivet washer of claim 2, wherein the fixing means is a bonding agent. ### Claim 4 (depends on 1) The blind rivet washer of claim 1, wherein the watertight or airtight membrane is connected along a perimeter of the washer body by a protrusion extending radially and circumferentially from the outer surface of the washer body. ### Claim 5 (depends on 4) The blind rivet washer of claim 4, wherein the watertight or airtight membrane is sealably watertight or airtight connected by friction pressure, a bonding agent, or any combination thereof. ### Claim 6 (depends on 1) The blind rivet washer of claim 1, wherein the watertight or airtight membrane is a material selected from the group consisting of silicone, silicone rubber, natural rubber, and synthetic rubber. ### Claim 7 (depends on 1) The blind rivet washer of claim 1, wherein the watertight or airtight membrane is silicone rubber. ### Claim 8 A blind rivet assembly, comprising: a blind rivet; a washer body with an outer surface including a circumferential portion of the washer body, an inner surface in contact with a substrate, and a rivet aperture through which a mandrel end of the blind rivet is insertable prior to the blind rivet being set; and a watertight or airtight membrane encapsulating completely the outer surface of the washer body, one side of the rivet aperture and the mandrel end of the blind rivet once inserted, wherein the watertight or airtight membrane creates a lumen which provides a space between a portion of the outer surface of the washer body and the watertight or airtight membrane into which the rivet mandrel end of the blind rivet is insertable and encapsulated. ### Claim 9 (depends on 8) The blind rivet assembly of claim 8, wherein the watertight or airtight membrane is sealably watertight or airtight connected to a perimeter, and optionally a circumferential portion of the outer surface, of the washer body by a fixing means. ### Claim 10 (depends on 9) The blind rivet assembly of claim 9, wherein the fixing means is a bonding agent. ### Claim 11 (depends on 8) The blind rivet assembly of claim 8, wherein the watertight or airtight membrane is sealably watertight or airtight connected to a perimeter of the washer body by a protrusion extending radially and circumferentially from the outer surface perimeter of the washer body. ### Claim 12 (depends on 11) The blind rivet assembly of claim 11, wherein the watertight or airtight membrane is sealably watertight or airtight connected by friction, a bonding agent, mechanical methods or any combination thereof. ### Claim 13 (depends on 8) The blind rivet assembly of claim 8, wherein the watertight or airtight membrane is a material selected from the group consisting of silicone, silicone rubber, natural rubber, and synthetic rubber. ### Claim 14 (depends on 8) The blind rivet assembly of claim 8, wherein the watertight or airtight membrane is silicone rubber. ### Claim 15 A blind rivet washer, comprising: a washer body with an outer surface including a circumferential portion of the washer body, an inner surface in contact with a substrate, and a rivet aperture through which a mandrel end of a blind rivet is insertable prior to the blind rivet being set; and a silicone rubber membrane connected to the washer body by a fixing means and encapsulating completely the outer surface of the washer body and one side of the rivet aperture, wherein the silicone rubber membrane creates a lumen which provides a space between a portion of the outer surface of the washer body and the watertight or airtight membrane into which the rivet mandrel end of the blind rivet is insertable and encapsulated. ### Claim 16 (depends on 15) The blind rivet washer of claim 15, wherein the fixing means is a bonding agent. ### Claim 17 (depends on 15) The blind rivet washer of claim 15, wherein the fixing means is mechanical. ### Claim 18 (depends on 15) The blind rivet washer of claim 15, wherein the silicone rubber membrane is connected via the fixing means along a perimeter of the washer body by a protrusion extending radially and circumferentially from the outer surface of the washer body. ### Claim 19 (depends on 15) The blind rivet washer of claim 15, wherein the washer body and the silicone rubber membrane form a single blind rivet washer assembly which the mandrel end of the rivet is insertable into on a blind side of the substrate. ### Claim 20 (depends on 15) The blind rivet washer of claim 15, wherein the silicone rubber membrane includes at least one raised pressure point skirt projecting from the membrane outward toward the substrate.
