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.
