Abstract: A waterproof membrane is described that includes a barrier layer and a functional layer. The functional layer can include a thermoplastic polymer that changes consistency under the influence of highly alkaline media, and an adhesive. The production and use of the membrane are also described. The functional layer of the membrane can be designed in the form of a film, a coating, or a nonwoven fabric. The fibers in the fabric can include a hard core that is surrounded by a polymer layer, is inert prior to coming into contact with liquid concrete and acts as a protective layer. Thus, the membrane is protected from premature aging and allows work to be performed with the seal in place. During the concreting process, i.e. when the functional layer comes into contact with liquid concrete, the polymer dissolves and thus allows the adhesive to bond to the concrete. The functional layer thus acts as an adhesive sealing compound and the seal is leakproof.

An actuator is constructed and arranged to displace the first of the plurality of tiles in a first direction relative to a second of the plurality of tiles.

Abstract: Water-activatable, linerless adhesive articles and related methods are described. The adhesive articles utilize a dry, non-tacky protective layer for protecting the adhesive layer from contamination and therefore do not require a release liner. The protective layer includes at least one of amorphous polyvinyl alcohol and poly(ethylene oxide). The adhesive articles are bonded to a substrate by applying a polar solvent, such as water, to the protective layer, which mix to form a tacky material. The tacky material forms a weak, temporary bond with the substrate and allows the adhesive articles to be repositioned on the substrate. The tacky material gradually pools together at the substrate/adhesive article interface to expose the underlying adhesive layer. The exposed adhesive layer then forms a permanent bond with the substrate.

Abstract: Disclosed roofing shingles and related methods of manufacturing provide a reinforced material that strengthens the bond between shingles by reducing the affect of heat on the sealant/adhesive between shingles in one or more areas where sealant/adhesive is applied or where it contacts other shingles once installed on a roof deck. The reinforcement material acts as fiber reinforcement to the sealant/adhesive. The reinforcement material intertwines with the sealant/adhesive, and thereby helps the shingles resist delaminating or slipping or blow-off when subjected to high heat conditions or on very steep sloped roofs. The reinforcement material helps retain the strength of the adhesive bond between shingles in these conditions by providing fiber reinforcement to the adhesive bond.
