GEOTECHNICAL & SUBSURFACE INVESTIGATION SERVICES
Foundations Begin Here
Geotechnical investigation and exploration are the foundation of every construction project — the design inputs require precise knowledge of soil and rock conditions. Vision operates a fleet of drilling rigs equipped to ASTM standards, supported by experienced engineers who deliver complete site characterization and foundation recommendations.
Services
Onshore Geotechnical Investigation
Boreholes, SPT, undisturbed sampling, cone penetration testing, dynamic cone penetrometer testing, and packer tests.
Slit Trenching & Test Pitting
Mechanical excavation for utility verification, fault-line investigation, and shallow soil profiling.
Environmental Site Characterization
Contaminated land investigation, soil and groundwater sampling, and environmental compliance reporting.
Offshore & Marine Geotechnical
Marine boreholes, vibrocoring, seabed CPT, and offshore site characterization from jack-up platforms.
In-Situ Testing (CPT SPT DCP)
Plate Load Test, Field CBR, permeability, electrical & thermal resistivity, pressure meter, seismic down-hole and cross-hole tests.
Geophysical Surveys
Seismic refraction, MASW, electrical resistivity, and downhole/crosshole methods for subsurface modeling.
Pile Integrity & Load Testing
Non-destructive method used to assess the structural condition and continuity of foundation piles.
