What We Do
Geological & Geotechnical Services
Stratum Group has established a reputation as the regional leader in geologic hazard, shoreline geology, and geotechnical assessments for residential and small commercial properties — with the experience to handle projects of any scale.
Our Approach
Tailored to Every Project
Our engineering geologists have decades of experience and are well suited to provide a broad range of geological and geotechnical assessments. Our expertise in the local geology and regulatory framework allows us to tailor each assessment to the project size and level of hazard, ensuring efficient and cost-effective evaluations and solutions.
Our services primarily include assessing potential geologic hazards and geotechnical issues for pre-purchase due diligence, evaluating and permitting new development, and providing mitigation recommendations. However, we are always open to the type of projects that suit your geological or geotechnical needs.
