Cascade Drilling was founded in 1991 as a highly regarded Northwest U.S. regional drilling company operating across three states. Cascade developed a strong reputation for safety, service and reliability with a particular emphasis on traditional drilling technologies: auger, rotary and direct push. From these roots the company has grown into a national, full service company offering innovation solutions for every step of your project, from environmental and geotechnical drilling to advanced site characterization and in situ and ex situ remediation applications. Our diverse portfolio of environmental, investigation and remediation services enable us to complete even the most challenging projects on time and on budget.
