Our Core Services

Underground Utility Locating
Quark Scan Inc. has extensive experiences in utility locating projects of all sizes, and specializes in industrial and commercial sites where complex underground utility situations often challenge skills of utility locators. Our utility locators have solid background in geophysics and have thorough understandings of advantages and limitations of all kinds of locating techniques. We often succeed where others fail.

Concrete Scanning
Drilling, coring, or saw cutting but concerned about utilities embedded in concrete? Don't just call a company because they provide GPR scanning services, give us a call for a comprehensive scanning! Our experts in geophysics not only use GPR, but also utilize state-of-art pipe/cable locators and Cable Avoidance Technology (C.A.T.). Besides locating steel and PVC electrical conduits, we also locate other utilities embedded in or below concrete slabs, even direct buried electrical/communication cables. In addition, we can also locate post-tension cables, rebar, and mesh when needed.

Underground Storage Tank Locating
While some underground storage tanks can be easily identified and located through record searching and visual inspection, others can be hidden underground without showing any indications of their existences. We use a set of tools including ground penetrating radar for UST locating and we have located many USTs, often to the surprise of our clients.

Geophysical Services
We utilize varieties of geophysical techniques to delineate subsurface conditions and locate buried targets. Geophysical surveys are non-destructive and they can provide valuable subsurface information for decision making about your construction, engineering or environmental projects. Our geophysical techniques include ground penetrating radar (GPR), electromagnetic induction (EMI), electrical resistivity imaging (ERI), and seismic refraction, to name a few.
