Geoprobe 8040 DT

RSI Drilling has brought direct push to a new level with the addition of the new Geoprobe 8040 DT. Unlike other DPT rigs, this powerful tracked rig can advance up to 4.5 inch casing and in more difficult subsurface conditions than the 6600 or 7700 series Geoprobes. This versatile rig also has hollow stem auger capability and is equipped with an auto-hammer for geotechnical work. The new GH80 hammer combined with 80,000 lbs. of pull back provides the most advancing and pull back power of any DPT rig in the industry. Call us to discover the possibilities of going deeper at sites where the 6600 and 7700 series have difficulties and get to the bottom of your problems (contaminants).

Compact Sonic Rigs



This rig is great for subsurface conditions too difficult for the 6600 series Geoprobes. It has the ability to advance different sized drill casing and is most efficient for remedial injection, continuous cores, or water sampling projects.

Air Knife Vacuum Excavator

RSI offers the safest and most efficient method of borehole clearance with the Vacmasters air knife system. The trailer mounted Vacmasters System 1000 can be operated with up to 200' of hose, allowing access to the most difficult to reach locations. The Vacmaster system uses compressed air to cut soils up to 95% of the time resulting in minimal IDW. Schedule RSI's air knife for your next project to ensure a safe drilling project.

Geoprobe 420M

RSI's latest rig addition is the Geoprobe 420M. This versatile Direct Push Rig is most applicable to indoor and difficult access borings. It's great for shallow soil vapor, water, and soil sampling and uses the reliable GH42 Soil Probing Hammer (same as the 5400 units). As you can see from the photos, the Geoprobe 420M can be mobilized by a crew of one and easily fits through standard-sized doorways as it is only 19" wide. It stands 62" high, and 94" with the probe cylinder fully extended. Consider this rig for your next indoor or difficult access borings!

Sonic Rig 116

This sonic rig is a Barber Dual Rotary 12/26 drill rig that is fitted with a RSD*300 drill head. It is mounted on an International 3 axle diesel carrier, has a self contained decontamination facility built right onto the deck of the rig, a pipe storage area on the deck of the rig, and an automated pipe breakout handling system which moves up and down the mast on separate 12' long cylinders to give greater flexibility while drilling. This unit has one of the larger sonic heads and can be adapted to use one of the high torque Barber tables to assist in the advancement of outer casing during the drilling process.

Sonic Rig 114

This rig is collecting continuous core soil samples at a site in the Northern California delta. This was followed with installation of a CMT multi-channel well (7 chambers in one well). This sonic drill rig is a Simco 5000AV manufactured unit mounted on a Ford 3 axle diesel carrier. It is fitted with a BRD*150 sonic head and can drill at angles from vertical to 45 degrees. This rig has a self-contained decontamination facility built onto the deck and side water storage tanks. It has an automated breakout system for tooling. The drill pipe is delivered to the rig from a forklift, so the footprint of the rig is half that of a standard sonic rig set-up where the support truck is parked end to end with the sonic rig.

CME High Torque Truck Mounted HSA Drill


RSI provides Hollow Stem Auger (HSA) drilling capabilities with High Torque CME-75 Rigs. The CME company has set the standard for HSA drilling with its durability and reliability. These high torque rigs (13,000 Ft-Lbs) are outfitted with heavy duty 3.25"-10.25" (i.d.) CME augers. Our rigs come fully equipped with CME auto-hammers for environmental and geotechnical sampling.

Tracked Geoprobe Rig

RSI provides fully equipped Geoprobe 6620DT Direct Push/Hollow Stem Auger track mounted rigs. These versatile rigs are equipped with Geoprobe's most powerful GH60 hammers and dual-speed auger heads. The Geoprobe 6620DT measures only 5' wide by 8' long. Requiring only 13' of overhead clearance the 6620DT is a great option for tight access drilling.

Geoprobe 6600

RSI has added two new Geoprobe 6600 4x4 trucks to its fleet over the past year. This Direct Push Drill Rig has the largest DPT hammer built by Geoprobe, the GH60 Soil Probing Hammer. It also has 20-tons pulling capacity, built-in rotary spindle for concrete coring, 42-gal. water transport system, and drop-down work tables. Mast oscillation allows easy alignment with probe terrain resulting in more drilling per day. This powerful DPT rig is capable of advancing the new, larger diameter probe rods (up to 3.25"), and RSI has drilled to a depth of 110' with this rig in the San Francisco Bay Area.

AMS PowerProbe 9630 - DPT and HSA all in the same rig!

This 18,000-pound combo rig is designed for quick assessment projects. With its 550 Ft-Lb hammer (175 Ft-Lb is industry standard), it will pound through difficult subsurface conditions considered refusal with a standard DPT rig. After collecting multiple continuous core, water, or vapor samples this PowerProbe can rapidly be switched over to Hollow Stem Auger (HSA) drilling to install traditional 2 inch or 4 inch monitoring wells. AND, this rig has twice the torque (5,000 Ft-Lbs) of other similar rigs. In summary, RSI's PowerProbe Combo rig is ideal for a combination of DPT and HSA drilling needs with one mobilization.

Geoprobe® 5400

The workhorse of the Geoprobe family, this direct push rig accepts most Geoprobe rods and tooling. Lateral movement of the unit provides for offset placement of the probe without moving the carrier vehicle. The 5400 has 25,000 pounds of pulling power, a 54-inch stroke, and is equipped with a GH40 Soil Probing Hammer. This rig is great for the collecting shallow surface soil, vapor, and water samples where the power of sonic rig is not needed.
