Application & Tooling

Direct Push Technology

Direct push technology allows for a wide variety of tooling and instrumentation to be advanced into a subsurface lithology using the static weight of the rig, hydraulic down pressure, and rapid hydraulic hammering. In many cases, direct push technology is the quickest and least expensive means to get desired samples. Such technology is used to perform soil, soil gas, and groundwater sampling. It is also used for soil remediation, and geotechnical sampling and testing. Many AMS PowerProbe direct push drill rigs also come equipped with hollowstem augering capabilities.

Direct Push Soil Sampling

Direct push tooling is highly effective in most unconsolidated lithologies, including sand, soft clay, tight silt, swelling clay, heaving sand, and gravel. Having the ability to recover continuous soil sample cores through holes that are slightly larger than the core itself is huge. Sampling can also be conducted with two separate rod systems. Having an outer drive casing that is advanced incrementally into the soil, and an inner rod string that is cycled through the drive casing to retrieve samples. Two rod systems offer improved sampling along with the flexibility to perform multiple sampling purposes in a single borehole. This is where soil gas, groundwater, and geotechnical sampling and testing can be managed.

Soil Gas Sampling & Monitoring

Soil gas sampling and monitoring with direct push methods are commonly used with soil gas surveys for the investigation of VOCs and other compounds that are considered health risks. We offer many sampling options that compliment a wide variety of regulatory and standard procedures. Sampling and monitoring soil vapor can be cost effective and simple with our tooling!

Groundwater Sampling & Monitoring

AMS groundwater samplers are often used for the initial site investigation because of the ability to rapidly sample a large number of locations. Having such a large sample size helps characterize water quality along with the extent of potential contamination. Small diameter groundwater monitoring wells are installed by direct push and can be temporary or permanent. Our monitoring well installation kits provide most materials needed for a quick and successful installation!

Soil & Groundwater Remediation

Depending on your preference, soil conditions, and job site requirements, AMS can provide the correct tooling to accomplish desired remediation tasks. Having the proper tooling to neutralize waste material or reduce the concentration of contaminants in the soil and/or groundwater is imperative. To learn more about our remediation tooling and how it can be utilized for your project, please contact AMS.

Geotechnical Sampling & Testing

Geotechnical sampling investigations can be conducted with direct push to depths over 100 ft. AMS sells a variety of Split-Spoon and Shelby Tube Samplers for geotechnical testing and sampling. They can be used with AMS direct push tooling instead of Hollowstem Augers to provide an efficient and clean way of obtaining samples. For geotechnical testing from the ground surface to approximately 10 ft., a variety of hand tooling equipment can be used in conjunction with direct push or independently, depending on the scope of work.

Hollowstem Augering

AMS's Hollowstem Augers provide the field technician the capacity to auger through difficult lithologies, including hardpan, for conducting Standard Penetration Tests, collect samples with Split-Spoons and Shelby Tubes for environmental and geotechnical investigations, and install conventional groundwater monitoring wells. AMS Hollowstem Augers can be used with auger drilling rigs, along with PowerProbe rigs that are equipped with augering capabilities. Versatility is brought to PowerProbe rigs with such capabilities by providing a means to reach deeper depths when conducting direct push activities telescopically through the auger itself.
