Engineered for Tight Spaces. Built for Serious Drilling.
The Rig: AMS PowerProbe 9130 VTR-D
Track-mounted maneuverability. Tracked, self-propelled platform travels across finished floors, landscaping, and rough terrain with minimal surface disturbance.
True limited-access footprint. Fits through a standard 36-inch commercial doorway, allowing drilling inside occupied buildings and other confined spaces.
Production-class power. Advances MC5 macro-core samplers to typical depths of 30 to 40 feet bgs (site conditions permitting), recovering continuous, intact soil cores.
Clean, representative samples. Continuous macro-core sampling provides detailed lithologic logging and high-quality samples for laboratory analysis.
Mobilization Ready
Big-Rig Capability. Small-Rig Access.
SEC owns and operates an AMS PowerProbe 9130 VTR-D, a track-mounted, limited-access direct-push drilling rig built for the sites conventional drill rigs can’t reach. Compact enough to fit through a standard 36-inch commercial doorway, the 9130 VTR-D brings full-size production power into basements, warehouses, courtyards, fenced utility corridors, and other tight or interior work areas—advancing MC5 macro-core samplers to depths of 30 to 40 feet below ground surface (bgs).
Because we own and operate our rig in-house, our clients get faster scheduling, seamless coordination between field geologists and drilling operations, and a single point of accountability from work plan through final report.
Low Clearance Sampling Capabilities
Where Limited-Access Drilling Makes the Difference Many of the Pacific Northwest’s most challenging subsurface investigations are in places a truck-mounted rig simply cannot go. Our limited-access rig is well suited to:
Interior investigations inside commercial and industrial buildings
Basements, loading docks, and covered or low-clearance areas
Courtyards, alleys, and densely developed urban parcels
Active facilities where minimal disruption to operations is essential
Sites with landscaping or surfaces that must be protected Applications
Our drilling services support soil exploration and geotechnical investigation, including:
Geotechnical soil borings and subsurface soil characterization
Soil sampling in support of Phase II Environmental Site Assessments
Pre-development and due-diligence soil exploration
Continuous soil core logging for geologic and stratigraphic evaluation
Soil sampling for laboratory analysis of contaminants of concern Licensing and Qualifications
All drilling is performed under the direction of a licensed geologist, whose license authorizes geotechnical borings for the purpose of soil exploration. SEC is a licensed, bonded, and insured contractor in the State of Oregon. SEC is not a licensed well constructor in Oregon or Washington and does not construct, alter, or decommission wells. For projects that require monitoring well installation or other well construction services, we coordinate with licensed well construction contractors as part of an integrated project team.
