Rock engineering and testing laboratory

Rock Engineering and Testing Laboratory (RETL) provided geotechnical engineering, geotechnical and environmental drilling, construction materials engineering, and testing services for industrial, municipal, infrastructure, and commercial development clients throughout the southern portions and coastal areas of Texas. While established in Corpus Christi, the firm expanded with offices in San Antonio and Austin/Round Rock.

Founded in 1998 by Mark and Roetta Rock, RETL and its team of 85 provided an exceptional level of responsiveness and technical expertise to our clients. Notable recent projects include the San Antonio Spurs Training Facility, the Multi-Assistance Center at Morgan’s Wonderland (the MAC), and the State Highway 211 Extension.
