The infrastructure of the United States is crumbling above, below, and around us. A considerable segment of the public and private engineering community is currently engaged in solving a geoÂmetrically increasing problem with geometrically decreasing funds. The problem is often compounded since maintenance of public works facilities must be paid for using public funds. This article will introduce a process for solving these problems that has actuÂally been around for many years-the process of using shotcrete or gunite to rehabilitate old, damaged, or otherwise substandard existing sewers.
Dry, Pre-mixed Shotcrete Supply for Tunnels and Mines
Tunneling and mining projects use shotcrete primarily as a means of ground support. Immediate application of shotcrete provides stability of the working face, preventÂing loose rock from initiating movement and thus permitÂting incremental advances of underground openings even in the worst ground conditions (type V rock) or clays.
