An interface transition for use in compression in connection with panels where air and/or water penetration is undesirable having a first body, a second body, an adhesive layer positioned intermediate the first body and the second body, and an impregnation into at least the first body, wherein the combination of the bodies, adhesive layer and impregnation reduces the air leakage rate therethrough and moisture infiltration therein after the interface transition is compressed to a width 75% of its uncompressed width. The interface transition may include an extension member for splicing and construction of a four-way intersection.

Interface transition and environmental barrier

An expansion joint seal proving a flexible barrier therethrough in a concave shape with a first body of compressible foam on one side and a second body of compressible foam on the other side, where the barrier extends laterally from the first body and second body and may be used to protect the sides of the expansion joint seal or may be used to provide contact on the surface of each adjacent substrate.

The present invention relates to a multi-layer fluid delivery device for post-installation in-situ barrier creation. The device provides a medium for post-installation injection of remedial substances such as waterproofing polymeric resins or cementitious materials, insecticides, mold preventatives, rust retardants and the like. The device comprises a first layer and a second layer, with optionally an intermediate layer therebetween, and a plurality of tubes extending outwardly from the first layer. The first layer is preferably semi-permeable; the second layer is non-permeable; the optional intermediate layer is a void-inducing layer. The multi-layered device is attached to a structural substrate and a construction material such as concrete or shotcrete is applied against its surface (and around the plurality of tubes). Thereafter, a free flowing active substance can be injected through the tubes to fill the air space in the multi-layered device.

Device for in-situ barrier

The present invention relates to a method for post-installation in-situ barrier creation by application of a multi-layered device. A multi-layered device provides a medium for of remedial substances such as waterproofing resins or cements, insecticides, mold preventatives, rust retardants and the like. The multi-layer device preferably consists of three conjoined layers: first layer, intermediate layer, and second layer, and at least one piping. The first layer is preferably semi-permeable; the second layer is a non-permeable layer; the intermediate layer is a void-inducing layer. The second layer, intermediate layer, and first layer are fixedly attached, with the intermediate layer interposed between the second layer and the first layer. The multi-layered device is fixedly attached to shoring system exterior surface. At least one piping is engagedly attached to a panel of the multi-layered device. A structural construction material is constructed exterior the multi-layer device. Thereafter, a free flowing substance can be pumped to the multi-layered device.

Device for post-installation in-situ barrier creation

The present invention provides compositions such as a polymer grout, a molded plastic part, a void-filling plastic material, a concrete-anchoring material and a polymeric casting made from a thermosetting polymer chosen from vulcanized rubbers, polyoxybenzylmethylen-glycolanhydride ('Bakelite'), novolac resins, resole phenolic resins, duroplast, bismaleimide resins, polyimide resins, melamine, acrylic resins, polyester resins, cyanate ester resins, phenolic triazine resins, paracyclophane resins and epoxy resins and at least one phase change material ('PCM'). The compositions of the present invention have a lowered exotherm compared to compositions made from the same thermosetting polymer without the addition of a phase change material. Also provided are improved processes for producing the inventive compositions.
