Early Age Strength Testing for Shotcrete: 2024

For improved safety in tunneling and mining projects that use shotcrete for ground support, early shotcrete strength should be evaluated by testing. Based on their range of effectiveness, two procedures stand out: The new Hilti BX 3-SCT stud driving method and the beam end tester.

Geohazard Mitigation: Why Shotcrete?

To improve safety and mitigate the risks of rockfall events along I-65 in Giles County, TN, GeoStabilization partnered with the Tennessee Department of Transportation and a local construction company.
