In Tulsa, subsurface investigation must address the region’s variable geology—from Arkansas River alluvium to expansive shale and limestone bedrock—which directly influences foundation performance. Our geotechnical investigation category covers drilling, sampling, and in-situ testing programs designed per ASTM standards and local Tulsa County regulations. A core component is the Cone Penetration Test, which delivers continuous soil stratigraphy and pore pressure data essential for evaluating soft clays and liquefaction potential in floodplain areas.
These investigations support commercial buildings, public infrastructure, and residential developments where bearing capacity and settlement must be confirmed before design. We pair CPT data with laboratory strength testing and standard penetration testing to build a complete ground model. For projects with deep foundation needs or karst concerns in eastern Tulsa, integrating CPT analysis with rotary drilling refines pile design and mitigates risk early.
