Abstract
The present invention relates to a device for post-installation in-situ barrier creation. 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.
