Services
Geotechnical Investigations
Our geotechnical investigations assess subsurface conditions through drilling, sampling, and testing. We identify soil properties, groundwater conditions, and potential hazards to inform foundation design. This critical first step ensures safe, cost-effective construction solutions tailored to project-specific needs.
Foundation Engineering
We design shallow and deep foundation systems based on site-specific geotechnical data. Our solutions address load requirements, settlement control, and seismic considerations. From residential pads to high-rise buildings, we ensure stable, code-compliant foundation systems.
Slope Stability
Our slope stability evaluations identify potential failure mechanisms in natural and man-made slopes. We implement mitigation measures like soil nailing, drainage systems, and reinforced walls to prevent landslides and ensure long-term stability for infrastructure projects.
Construction Monitoring
We provide on-site quality control during earthwork and foundation construction. Our technicians verify compaction, inspect shoring systems, and ensure compliance with design specifications. This proactive approach prevents costly delays and maintains structural integrity throughout construction phases.
Environmental Services
Our environmental team conducts Phase I/II assessments, soil contamination testing, and remediation planning. We help clients navigate regulatory requirements for property transactions and redevelopment projects, ensuring environmental compliance and risk mitigation.
