Services
Geotechnical Engineering
Our geotechnical engineering services provide comprehensive subsurface investigations and foundation design solutions. Utilizing advanced equipment like the Marchetti Flat Plate Dilatometer, we assess soil properties to develop cost-effective engineering recommendations. With expertise in settlement analysis and groundwater control, our team delivers tailored solutions for projects ranging from local developments to international facilities.
Construction Materials Testing
We offer full-spectrum construction materials testing for soil, concrete, masonry, and asphalt. Our NICET-certified technicians perform field inspections and laboratory analysis to ensure compliance with ASTM standards. Services include compaction testing, strength verification, and problem resolution during construction phases, maintaining strict quality control throughout project execution.
In-House Drilling
Our dedicated drilling division provides rapid mobilization for site investigations. Using two all-terrain drill rigs operated by experienced crews, we collect soil and rock samples for accurate subsurface analysis. This capability enables precise foundation recommendations and supports our engineering team's comprehensive project evaluations.
Laboratory Testing
Our AAP-accredited laboratory conducts extensive testing on construction materials following ASTM and AASHTO standards. Services include triaxial soil testing, concrete strength analysis, and asphalt performance evaluations. With controlled calibration and rigorous quality assurance, we deliver reliable data to support engineering decisions and construction compliance.
