Advanced Remediation Equipment & Technology
IET's 50+ specialized rigs — Geoprobe, CME, AMS, Schramm, and barge systems — combined with custom injection trailers and mixing equipment, give IET the capability to mobilize the right equipment for any site, formation, or access challenge in the US.
IET's Equipment Fleet
All rigs are owned and operated by IET — no subcontracting of core drilling and injection work.
Geoprobe Direct Push Rigs
IET operates a fleet of Geoprobe direct push rigs — the industry standard for environmental drilling, soil sampling, and amendment injection. These track- or skid-mounted rigs advance small-diameter tooling to depths of 80–150 ft without the need for drilling fluids, minimizing cross-contamination between sampling intervals.
Key Applications
- Discrete interval soil and groundwater sampling
- In-situ amendment injection (ISCO, ERD, ISCR)
- Monitoring well installation (1–2 inch)
- Soil vapor probes and VOC screening
AMS Direct Push Rigs
AMS direct push rigs provide a lightweight, low-profile alternative for access-restricted sites — indoors, under low clearances, or on terrain where track rigs cannot operate. The AMS 9800 PowerProbe is a favorite for interior drilling and tight-access environmental projects.
Key Applications
- Interior floor and basement drilling
- Tight-access and low-clearance environments
- Shallow soil and groundwater characterization
- Rapid multi-point injection programs
CME Hollow-Stem Auger Rigs
CME hollow-stem auger rigs are IET's primary platform for monitoring well installation, geotechnical borings, and soil mixing programs requiring larger borehole diameters. The hollow stem allows sampling, testing, and well installation while the auger remains in the hole — preventing borehole collapse in soft soils.
Key Applications
- 2-inch to 4-inch monitoring well installation
- Standard penetration testing (SPT)
- Split-spoon soil sampling
- Large-diameter soil mixing programs (ISGS)
Schramm Rotary Drill Rigs
IET's Schramm rotary rigs handle the most demanding geotechnical and environmental drilling challenges — deep borings, rock formations, and high-torque applications that exceed the capacity of direct push or auger equipment. The T64 and T130XD are widely regarded as the most capable truck-mounted rotary rigs in the industry.
Key Applications
- Rock coring and geological characterization
- Deep monitoring well installation (> 100 ft)
- Air rotary and mud rotary drilling
- Geotechnical test borings in competent rock
Barge-Mounted Drilling Systems
IET operates dedicated barge-mounted drilling platforms for over-water environmental and geotechnical drilling — accessing riverbanks, lake beds, harbors, and coastal sites where land-based equipment cannot reach. IET's barge systems can be configured with CME, Schramm, or AMS rigs depending on the required borehole diameter and depth.
Key Applications
- Over-water monitoring well installation
- Riverbed and harbor sediment sampling
- Waterfront industrial and Superfund sites
- Offshore geotechnical investigations
Custom Injection Trailers & Mixing Systems
Beyond drilling rigs, IET operates a fleet of purpose-built injection trailers, mixing tanks, and reagent delivery systems designed specifically for in-situ amendment programs. These custom systems provide precise flow control, pressure monitoring, and reagent proportioning for large-volume ISCO, bioremediation, and ISCR injection events.
Key Applications
- High-volume ISCO oxidant delivery
- Multi-point bioremediation injection manifolds
- ZVI and EZVI slurry preparation and pumping
- Reagent blending and quality control on-site
Why IET Owns Its Equipment Fleet
IET doesn't subcontract core drilling and injection work. Here's why it matters.
Quality Control
IET crews operate IET equipment. No subcontractor training gaps, no split accountability. One team from planning to execution to performance reporting.
Specialized Configuration
IET's rigs are configured for in-situ remediation work — injection tooling, reagent delivery systems, flow monitoring — not generic drilling. The difference shows in the results.
Scheduling Flexibility
IET's equipment availability is controlled by IET, not a subcontractor's schedule. Urgent projects get mobilized fast — and complex multi-rig programs are coordinated in-house.
