Services
Construction Material Testing
Our construction material testing evaluates soil, concrete, steel, and asphalt properties following ASTM and TxDOT standards. Skilled technicians perform slump tests, density measurements, and mix design verification to ensure structural integrity. This service supports infrastructure projects with quality control data for compliance and performance assurance.
Geotechnical Engineering
Geotechnical investigations assess subsurface conditions through boreholes, lab testing, and engineering analysis. We provide foundation recommendations, settlement analysis, and soil stabilization solutions adhering to AASHTO specifications. Expert evaluations support pavement design and earth retaining structure development for transportation and commercial projects.
Environmental Compliance Audits
Environmental audits verify facility compliance with local, state, and federal regulations. Services include permit acquisition, pollution control system design, and storage tank management. Our team assists clients in developing environmental management programs to maintain regulatory compliance and operational efficiency for industrial facilities.
Non-Destructive Testing
Non-destructive testing employs ultrasonic, impact echo, and ground penetrating radar techniques to assess structural integrity without damaging components. Certified inspectors evaluate steel welds, bolt torque, and concrete reinforcement positioning to ensure construction quality meets engineering specifications and safety standards.
Drilling Services
Our drilling rigs perform dry or hollow stem borings up to 40 feet with subcontractor support for deeper sampling. Field crews with extensive groundwater experience collect soil and rock samples for laboratory analysis. This service provides essential subsurface data for foundation design, environmental assessments, and infrastructure planning.
