In-situ Remediation Services

JHA Remediation (JREM) owns multiple Direct Push Sampling Rigs and is fully prepared to support you in your site characterization and remediation projects. JREM rigs offer a reasonable alternative to other drilling methods. Our rigs are hydraulically-driven direct push boring and sampling systems.

Direct push technology, often referred to as DPT, uses the static weight of the rig combined with a hydraulic hammer to advance tooling or instrumentation through the subsurface. Unlike rotary, the drill cuttings are not removed from the borehole, thus minimizing, and in most cases, eliminating the cost of soil disposal. The speed and depth of penetration is largely dependent on the soil type, the size of the sampler, and the weight and power of the rig.

These systems can be used to perform subsurface soil, water or soil gas surveys. They are capable of obtaining soil and groundwater samples, installing standard and pre-packed monitoring wells and multi-nested soil gas wells. They can drill and set piezometers, inclinometers, and soil gas points; and support direct imaging and injection of a variety of remediation compounds.

When applicable, this method allows for the collection of high-quality samples in less time and at lower cost.
