    Abstract: Provided is a pre-applied waterproofing membrane having a waterproofing adhesive layer and an outer particle layer comprising synthetic polymer granules to protect the adhesive layer and to facilitate detailing at membrane-to-membrane overlaps. In preferred embodiments, the synthetic polymer granules are made from polymers selected from the group consisting of polyvinyl acetate, acrylic, and styrene butadiene copolymers or polymers. Most preferably, the synthetic polymer granules have round or spherical shapes that help to facilitate detailing at the building or installation site, such as sealing at membrane overlaps, and sealing around pipes or other details. Alternatively, the membranes may be made having side edges which are free of synthetic polymer granules, whereby a removable release liner strip can be used to prevent adhesive from sticking to the back of the membrane when the membrane is rolled up on itself for shipment.

    Abstract: The invention provides a waterproofing membrane which does not require a removable release sheet but which nevertheless bonds to post-cast concrete and facilitates water-tight sealing at membrane-to-membrane overlaps. The waterproofing membrane comprises a carrier and pressure-sensitive adhesive (PSA) layers, an inorganic particle layer having particulate bodies which are partially embedded in the PSA and which have an average particle size less than the average thickness of the PSA layer, and an anti-submarining nano-silica-containing coating layer attached to un-embedded portions of the inorganic particles to prevent total embedding into the PSA when the membrane is rolled or unrolled, whereby water-tight seams are facilitated between overlapped portions of adjacently installed waterproofing membranes, and whereby the water-tight seam is achieved preferably using only detailing or waterproofing tape and without the additional use of a liquid primer, mastic, or other coating.

    Abstract: Methods and systems of the invention, for achieving a liquid-applicable, aqueous-based coating composition that forms a water-impermeable, vapor permeable barrier coating when applied onto a construction surface and allowed to dry, involve mixing together separate first and second components, wherein the first component comprises an acrylic emulsion, flame retardant, clay, and optionally at least one additive selected from thickeners (e.g., cellulosic), fillers, and other conventional additives; and wherein the second component comprises a freezing point depressing agent with a specific type of thickener selected from the group of associative thickeners, alkali soluble emulsion thickeners, or mixture thereof, to obtain the liquid-applicable coating. The present invention achieves low temperature film formation without reliance upon calcium nitrite, calcium nitrate, or sodium chloride type of freezing point depressing salts. The coating can be applied at low (e.g., sub-freezing) temperatures onto a construction surface such as wood, fiberboard, gypsum, cement, concrete, and other building substrates to achieve an effective barrier membrane.

    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: 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 ⅛ 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.
