Patent ID: 8201287

Claim:
A water barrier comprising, a water bearing floor including an upper surface forming a water receiving cavity and a first notch disposed on the upper surface along a first edge of the upper surface of the water hearing floor; a vertical water bearing material resting on the first edge of the upper surface of the water bearing floor including a first surface including a non-porous material facing the water receiving cavity and a second surface facing away from the water receiving cavity; a vertical water barrier membrane inserted into the first notch and adjacent to the second surface of the vertical water bearing material whereby the combination of the first notch in the upper surface, the vertical water barrier membrane inserted into the first notch and the vertical water bearing material form a wall-to-floor seam; a threshold having a top edge, an interior edge facing the cavity, and an exterior edge; a second edge of the upper surface of the water bearing floor adapted to conform to the top edge and the exterior edge of the threshold; an external water barrier membrane disposed on a floor next to and in close proximity to the exterior edge of the threshold; a third water barrier membrane forming a substantially, ninety degree angle with a horizontal surface resting on top of the external water barrier membrane and a vertical surface placed adjacent to the exterior edge of the threshold; and a flooring material resting on top of the horizontal surface of the third water barrier membrane and the external water barrier membrane; wherein the second edge of the upper surface of the water hearing floor is placed adjacent to the vertical surface of the third water harrier and on top of the horizontal surface of the third water barrier membrane and adjacent to the flooring material so as to form a floor-to-floor seam.
