Abstract
An underground support system having an underground reinforcement system that is at least partially encapsulated with concrete or a cement material. The underground reinforcement system includes a flexible wire mesh having a matrix of longitudinally and transversely extending metal wires. The matrix of longitudinally and transversely extending metal wires has at least one three-dimensional sheet, each sheet having at least one raised corrugation, positioned along the length of an underground space. The raised corrugation acts as a template depth girder for application of concrete or cement material at a defined depth such that the underground reinforcement system is at least partially encapsulated with the concrete or cement material.
