Welcome to CTI Inc.

CTI Inc provides services on several dozen projects each year. Our culture, systems and structure enable us to excel at both small and large projects. By combining our national resources with specific local area expertise, we consistently overcome obstacles and deliver the results our clients expect.

Before owners can build highways, dams, buildings and other structures, they need a company service to help determine how the characteristics of the soil conditions on the site will react under the stress caused by the weight of the structure. CTI is the company that can determine those conditions using geotechnical instrumentation for reliable results.


CTI Inc is proud to be celebrating their 19th year in business!
