Subsurface Investigation ​

Geotechnical field services to inform design, reduce risk, and support construction planning ​

D.W. Kozera, Inc. provides subsurface investigation services that deliver essential soil data for foundation design, grading, and site development. Our geotechnical team works closely with engineers, developers, and project owners to evaluate subsurface conditions and provide the technical information needed to guide decisions throughout the design and construction process. ​

Whether your project involves shallow foundations, deep foundations, slope stability, or pavement design, we tailor soil exploration programs to site-specific conditions, project goals, and permitting requirements backed by detailed documentation and practical recommendations. ​
