The present invention relates generally to a below grade, blind side, waterproofing sheet membrane with adhesive and low reflectivity granular particle layer to fully bond to concrete/shotcrete, and a method of making, and using same. More particularly, the invention encompasses a below grade, blind side, waterproofing sheet membrane with adhesive, and having at least one layer of low reflectivity granular particle layer that are fully or partly embedded into the adhesive layer, and where the average reflectivity of the exposed granular particles is below about 50 percent reflectivity on a standard reflectivity scale. The inventive waterproofing layer having the waterproofing sheet membrane, and an adhesive layer having embedded therein low reflectivity granular particles can be used in any building or wall construction, and can be placed under or around a foundation of a building or dwelling or on its below grade blind side retaining walls, etc.

A water-impermeable membrane assembly for sealing a surface of a substrate comprises a waterproofing sheet and a plurality of conduits having openings in at least a first major surface, and a leak-alarm circuit disposed at least partly within said equipment space, the leak alarm circuit having a leak-alarm target operative to trigger activation of the leak-alarm circuit when in contact with a water-containing liquid. The leak-alarm circuit comprises an electronic circuit comprising a transmitter and a battery for transmission of a signal. The assembly also includes a capillary pathway disposed within at least a portion of the conduits, including at least one conduit in fluid communication with the equipment space and with respective openings disposed in at least said first surface, so as to provide a pathway for transport of a water-containing liquid by capillary action from said openings to said leak-alarm target.

A prefabricated flashing product for an opening in an exterior surface of a structure includes a generally planar flange shaped to conform to the exterior surface, the flange extending outwardly from an entire perimeter of an aperture therein that corresponds to the opening, and a return that seals to the flange about the aperture and extends substantially perpendicularly therefrom toward an inward direction of the opening. The flange and the return are monolithically formed of a waterproof material. A method of integrating a fenestration product into an opening of an exterior surface of a structure includes inserting the flashing product described above into the opening, and inserting the fenestration product at least partially into the aperture of the flashing product.

The present invention relates to a below grade, blind side, improved dual waterproofing membrane assembly incorporating a secondary membrane comprising of a bentonite sheet waterproofing layer, and a primary membrane comprising of a sheet membrane having an adhesive to fully bond to a concrete/shotcrete. The invention encompasses a dual layer or dual membrane system that acts as a barrier, and prevents, and blocks water and moisture, from passing from one side of the structure to the other side. The dual barrier layer system can be used along a wall, a floor, a ceiling, or along any structure which requires water or moisture proofing. The invention can be used between a concrete or shotcrete layer and the surrounding earth, such as, along an area that has a high water table, or a constant hydrostatic pressure, or high ground moisture, that may creep into a foundation or a wall.

A protective barrier that will typically be installed beneath ceilings during construction work being performed on ceilings or roofs of buildings. The protective barrier can be comprised entirely of one material or of different materials connected by seams. Some or all of these materials can be designed to fail when contacted by water via dissolution, melting or through some other destructive process initiated by contact with water. Some or all of the materials comprising the protective barrier can be designed to fail at a certain temperature. This failure can create access points from the ceiling through the protective barrier to the area being protected by the barrier, which can allow water from a fire suppression system to reach a fire located below the protective barrier.

The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.

A multilayer film is provided. The film includes a first inert layer, a first tie layer, a nail sealable layer, a second tie layer, and a second inert layer. Where, the nail sealable layer is between the first tie layer and the second tie layer, the first tie layer is between the first inert layer and the nail sealable layer, the second tie layer is between the second inert layer and the nail sealable layer, the total film thickness is between 0.002 inch and 0.010 inch, and the film has a Water Vapor Transmission Rate of less than 0.5 grams per one hundred square inches per day.
