Expanded Direct Push and Injection Capabilities

Holocene Drilling has expanded our Direct Push and Injection capabilities with the addition of Anisa and Don Harnden, formerly of ESN.  They bring their 25+ years of direct push and remediation experience to assist you with any Phase II or Phase III projects throughout Washington and Oregon.  Also joining us are several of their former drillers and crew members as well as additional full size probe rigs, limited access rigs and injection equipment.

Contact Anisa at Holocene Drilling to discuss our expanded direct push/injection services and to book your next project.  She can be reached at: AHarnden@Holocenedrillinginc.com or at 253-848-6500.

Geotechnical Drilling


Geotechnical site investigations help determine subsurface soil conditions, including stability, soil classification, and formation changes.  They also examine groundwater depth, movement, and its impact on soil stability. Holocene provides a wide variety of geotechnical drilling services.
