Subsurface Investigations
Our subsurface investigations provide critical data for infrastructure and construction projects. Using advanced drilling, sampling, and testing techniques, we assess soil, rock, and groundwater conditions to inform foundation design and mitigate risks. Our AASHTO-accredited labs ensure accurate analysis for projects ranging from dams to transportation systems.
Environmental Services
We specialize in environmental assessments and remediation support for contaminated sites. Our services include sediment sampling, groundwater monitoring, and hazardous material analysis. With expertise in regulatory compliance, we assist clients in industries like energy and manufacturing to achieve sustainable cleanup solutions for lakes, rivers, and industrial sites.
Construction Materials Testing
Our construction materials testing ensures compliance with engineering specifications and safety standards. We perform concrete, asphalt, steel, and soil testing for commercial, transportation, and industrial projects. On-site labs provide real-time quality control, supporting major infrastructure developments like bridges, airports, and distribution centers.
Nondestructive Testing
We employ advanced nondestructive testing methods to assess structural integrity without compromising materials. Services include ultrasonic steel testing, ground-penetrating radar, and concrete core analysis. These techniques support maintenance and safety assessments for bridges, dams, and high-rise buildings across New York and beyond.
