Capabilities

DA Smith is experienced with drilling, coring, and pressure-grouting holes in concrete arch and gravity dams across the United States. Past projects have involved core drilling to investigate concrete integrity and bedrock contact, concrete sampling for mechanical properties testing, in situ stress measurements inside dams, and installation of geomechanical instrumentation. We work with private dam owners, government owners, engineering firms, and heavy civil constructors, and can adapt our equipment to fit virtually any project.
