Design and construction of functional, cost-effective structures require a thorough understanding of local soil, rock and groundwater conditions. At TERRA we strongly believe that drilling, sampling and field testing requires expertise to meet exacting standards and perform every task with accuracy and without compromising results.
The method and precision of obtaining data directly influences the decision of foundation recommendations of that specific site. Therefore, unlike other geotechnical firms, TERRA owns and operates a fleet of three (3) TxDOT certified drill rigs, and the dynamic penetrometers are energy calibrated in accordance with ASTM D 4633. Our Lead Drillers have over 25 years of experience and are NICET & TWDB certified. Since, TERRA owns and operates our own equipment, the result is a controlled response to the project schedule which helps to maintain a good customer service.
