In Eugene, many projects hit a wall when the geotech report lists numbers the structural engineer can’t use directly. That’s where a dedicated soil mechanics study comes in. We take the raw SPT blow counts, the lab triaxial curves, and the grain-size distributions and turn them into design parameters—bearing capacity, settlement, lateral earth pressure. The Willamette Valley has a mix of alluvial silts, gravel stringers, and weathered clay that behaves differently at every site. A CPT test across the floodplain near the Willamette River gives us continuous stratigraphy without the disturbance of traditional sampling, which helps refine the stiffness profile for settlement analysis. Our team works with local architects and builders to make sure the foundation recommendations match how the structure actually loads the ground, not just what a textbook says.
We don’t hand you a boring log and walk away. We give you the friction angle, the cohesion, the modulus, and the settlement curve—everything the structural engineer needs.
