    Abstract: An integrated air barrier assembly is provided as an integral product in which a fastener-sealing layer is secured between opposed surfaces of a board and an anti-blocking facing layer. The assembly exhibits good fastener sealability, including for larger self-drilling screws. The anti-blocking facing layer maintains the fastener-sealing layer inward of the environment and prevents blocking or sticking of the assembly when stacked. In some embodiments, the anti-blocking facing layer can be a metal film or foil, which can reflect heat away from the fastener-sealing layer, thereby maintaining a lower temperature on the fastener-sealing layer. In some embodiments, the board can be an insulating layer or wood layer. The assembly can be readily installed in a single step during construction.

    Abstract: The present invention provides a multi-layer barrier assembly or device for post- installation injection of a resin, grout, or other fluid fluid. The barrier device comprises first and second layers defining an intermediate open-matrix layer, and at least one injection conduit member in parallel orientation with respect to the first and second layers and having openings for injecting fluid into the intermediate open-matrix layer. The injection conduit may be located between and in parallel orientation with respect to the first and second layers, along an edge of the first and/or second layers, along an outer face of the first layer (if the first layer is a woven or nonwoven fabric), or at any combination of these locations, to enable fluid to be conveyed into the intermediate open-matrix layer. The invention also provides for use of a gel activator within the barrier device cavity, such as pre-installed on open-matrix structure which used for separating the first and second layers of the barrier device, such that a highly flowable injection fluid can be introduced into the device, and its gelation or hardening will be initiated or accelerated by the presence of the gel activator. This will allow for low power grout pumps to be used and facilitate the sealing of fine cracks in the surrounding concrete.

    Abstract: A water vapor impermeable flooring underlayment membrane of the present invention comprises a non-woven layer have first and second major faces, a first coating on the first major face of the non-woven layer, and, on the second major face, a water-vapor impermeable polymer layer, and a pressure sensitive adhesive layer partially coated on the polymer layer, the pressure sensitive partial coated adhesive layer being covered by a release liner. The use of partial coating pressure sensitive adhesive layer allows for quicker and more convenient floor installation compared to prior art box grid taping processes.

    Abstract: The present invention provides methods and articles for achieving puncture- resistant waterproofing membranes and for waterproofing building and civil engineering surfaces without requiring the use of separate protection boards. Exemplary membranes and methods of the invention rely on relatively thin, flexible composite layers to provide impact resistance while yet facilitating seaming between adjacent installed membranes and minimizing formation of wrinkles, leakage channels, and "fish mouth" openings, particularly at substrate details or other surface irregularities.

    Abstract: The present invention provides a panel sheathing for making wall and roof structures in which the panels (e.g., wood boards, oriented strand boards, plywood, etc.) are pre-coated at a factory, before installation at the building/construction site, using a polymeric barrier coating having specific water permeability, self-sealing properties with respect to penetrated metal fasteners (e.g., nails) in accordance with ASTM D7349 (modified using 1.5-5.0 inches water depth in hydrostatic head testing over sample of coated panel in which a steel nail is driven to within 1/8 inches of being flush with the panel and conditioning the test specimen for 24 hours at 23° C prior to hydrostatic loading), as well as anti-blocking properties whereby the coated panels can be transported in stacked configuration without sticking or disintegration of the polymeric barrier coating. The coated panels do not require the use at the installation site of felt paper, house wrap, or additional applied barrier coating to provide excellent weather barrier properties. The present invention also provides methods for constructing the panel sheathing structure as well as for making the coated panels.
