Micro-Gravity for Sinkhole Investigations

Gravity or micro-gravity surveys consist in measuring the relative changes in gravity from one place to another. Sharp relative changes in micro-gravity usually evidence drastic changes in the subsurface density of the underground material. This method allows us to identify the geological scenario for sinkholes with the potential of damaging existing structures earlier in their development without more expensive and invasive techniques. Results of one such survey are illustrated in the image to the left. The low micro-gravity anomaly (indicated in purple) help narrow down the areas of concern. Follow up actions from geotechnical or civil engineers can concentrate further investigative effort

Enviroprobe's New Geoprobe 8140LS Sonic Drill Rig

We are proud and excited to share our recently acquired Geoprobe 8140LS Sonic Drill Rig with our clients. The 8140 replaces our previous sonic rig with the intentions of still reaching the same desired drilling targets, but at a more affordable cost. The main idea in the decision to go with the Geoprobe Sonic Rig was to be able to mobilize and demobilize the machine ourselves. Often the hefty cost of having a low boy truck hauling our previous machine was too costly a price for our clients to work into their projects. The new machine is hauled by our drillers in house and the savings are able to passed along to our partners. Our new 8140LS features a powerful 30K roto-sonic drill head capabl
