Abstract: A plug for a void in a mine to divert water having a rigid closed cell foam which fills the void. The rigid closed cell foam having a plurality of pipes disposed within the foam. The pipes distributed throughout the void. The pipes are positioned in the foam so the pipes are staggered in length vertically with respect to various heights in the void, and the pipes are positioned in the foam every 4? to 6? horizontally with respect to the void. Each pipe has a mixing stick. A method for diverting water from a void in a mine.

Abstract: A wall having a 3D wire mesh panel having a core with a 3D wire mesh matrix extending through and out the core, and a structural material, such as concrete, envelopes the panel. A form positioned about the panel is used to introduce the concrete to the panel during production. Methods for producing the wall, which include producing the wall vertically at a desired location.
