HTAS™

What is HTAS™?

Continuous Core Sampling Where Conventional Drilling Can’t Go

HTAS™(Hard-to-Access-Sampling) is a cost- and time-efficient sampling technology developed by QRI to collect continuous core samples in hard-to-reach environments, including impoundments, pits, marshes, swamps, and restricted industrial locations—all with minimal site disturbance.

Reliable Sampling in Challenging Environments

HTAS™ uses lightweight, highly mobile equipment designed to access areas that are impractical or impossible for traditional coring methods. The system eliminates the need for road construction, drilling fluids, or heavy infrastructure, significantly reducing environmental impact and site preparation time.

Unlike standard coring technologies, HTAS™ excels at retaining highly fluid sludges while maintaining sample integrity. Its mobility and performance in difficult terrain make it an ideal solution for environmental investigations, geotechnical assessments, and remediation projects where access, accuracy, and efficiency are critical.

Continuous coring provides accurate characterization of site stratigraphy, including material depths, soil textures, and stratigraphic contacts. These continuous cores enable precise volume estimates of contaminated materials, pit liquids, and impacted soils. Collected samples can be used for a wide range of applications, including chemical analysis, geologic interpretation, volume calculations, remediation planning, and geotechnical testing.

This method also offers an efficient solution for installing shallow monitoring wells in difficult or inaccessible locations, such as beneath pipe racks, within confined spaces, and in ponded areas.

Whether working at traditional or non-traditional sites, QRI’s team of experts delivers reliable solutions tailored to your sampling needs.
