Rock & Materials Testing

RESPEC provides clients with advanced and specialized rock testing and research to support the complete characterization of a rock’s physical composition. Our testing also evaluates the mechanical, hydrological, and thermal behavior of the rock to offer clients and engineering analysts with the properties data they need to support mining engineering studies.

Our state-of-the-art Materials Testing Laboratory and facilities have more than 10,000 square feet of monitored, secure, and environmentally controlled floor space to ensure accurate data when preparing samples and testing rock. We conduct standardized testing according to the methods recommended by ASTM International, the International Society for Rock Mechanics, the International Organization for Standardization, and the American Petroleum Institute.

Our laboratory team uses sophisticated equipment that accurately simulates complex in situ stress and temperature conditions. Since 1969, our Materials Testing Laboratory has customized its testing capabilities and services to meet the unique needs of our diverse national and international clients that include government agencies, national laboratories, architectural and engineering firms, mining companies, and the oil-and-gas industries.

The laboratory also houses an environmentally controlled core-logging laboratory and a core storage facility. This space allows our geology team to clean, prepare, package, photograph, describe, and gamma-log the core in a controlled environment.
