Abstract: The present invention provides a non-cured-in-place waterproofing pressure-sensitive adhesive having a microfibrillar additive for achieving ideal balance between sag resistance at elevated temperatures and good adhesion at low temperatures. Waterproofing membranes comprising a carrier sheet and pressure-sensitive adhesive layer are also described, along with methods of manufacture.

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.
