"The ground is snow covered, is it OK for the GPR survey?" This is a very common question from our clients. Ground penetrating radar (GPR) actually works well through snow or ice. Below is a GPR profile showing an underground storage tank (UST) with ground covered by about 4 to 6" of snow. The located UST was marked on-site as in the picture to the right. Although snow or ice on the ground surface wouldn't block GPR signals, it's not a favorable working condition for some typ

Ground penetrating radar (GPR) has many applications. One of its applications in engineering is to delineate lateral extents of footings for bridges, buildings and other structures. Design and as-built plans are not always available when needed and a GPR survey could provide valuable information about the footings in a non-destructive and efficient way. The GPR profile below shows a concrete footing with reinforcement. The top of the footing was about 3' underneath a concrete

It's a very common practice for environmental consultants to get soil samples around underground storage tanks (USTs). The selection of drilling locations depends on a lot of factors and sometimes it's preferable that they are located as close as possible to USTs without risking damaging them. Ground penetrating radar (GPR) is a great tool to use to delineate UST scopes due to its very high lateral resolutions. GPR can be used to delineate scopes of USTs made of steel or fibe

Traditionally, results of electromagnetic surveys utilizing EM instruments such as Geonics EM31 or EM61 are usually presented in contour maps. A picture is worth a thousand words -- these data contour maps, especially when drawn in colors, can be very powerful presentation materials showing details of investigation results. However, when the budget of a project is limited, it’s possible to lower the survey cost, but still achieve the same investigation goal without contour ma

Over the years, the geophysical service provided by Enviroprobe for environmental and engineering communnities has grown tremendously. Our geophysicists and geophysical technicians employ varieties of geophysical methods including but limited to: ground penetrating radar (GPR), precision locating (for underground utility lines), borehole geophysical logging, DC electrical resistivity, sub bottom profiling, seismic, and EM mapping. Our services include but not limited to: Loca

Enviroprobe recently purchased a Dando SDC375 Roto-Sonic drilling rig equipped with the Sonicor 50K drill head. It is a multipurpose sonic drilling rig capable of continuously collecting large diameter undisturbed samples at much higher rates than conventional drilling methods. Its compact and powerful design, featuring the industry leading Sonicor 50K rotary head, offers great flexibility for a range of drilling applications including mineral, water, geotechnical and GSHP. T

We are proud to announce that Enviroprobe Service, Inc. will be a sponsor of 3rd Annual Southwest Florida Brownfield Symposium. As a company providing drilling and geophysical services for more than 20 years, being a sponsor of the symposium is our continuing effect to support environmental communities. The symposium is to be held on March 20, 2015 in Fort Myers, FL. Its goal is to assist you in putting your Brownfield puzzle together as you thrive towards economic enrichment

As part of a project for tracking down overflowed oil, Enviroprobe conducted a geophysical survey to delineate the bedrock topography around a tank field. The seismic refraction was the primary investigation method and an EM31 survey was also conducted as a quick complementary method. The 2D seismic refraction survey was conducted along parallel lines and the results were interpolated for the bedrock topography. One of the important discoveries was that the elevations of the

We’re frequenctly requested by clients to bring “concrete GPR” to sites for searching something underground. However, sometimes these requests were based on the misconception of concrete GPR. Just because the medium is concrete it does not mean that the "concrete GPR” is the best approach. The main difference between a concrete GPR and a regular GPR, such as those for underground utility locating and underground storage tank locating, is the antenna frequency. The antenna fre
