Subsurface Exploration

CSI performs subsurface exploration to obtain information about the condition of soil layers below the project surface.

If you are looking for subsurface exploration services, Consulting Services, Inc. (CSI), headquartered in Lexington, Kentucky and also with offices in Cincinnati, Ohio, has been in the business of providing geotechnical engineering services, including subsurface exploration, since our incorporation in 2009. Founded by several engineers, CSI continues to grow our team with engineers and other professionals critical to the work we perform. All of our engineers have 15+ years of experience in this work and we have built an excellent reputation for our geotechnical expertise.

One of the critical areas of client work that we provide is subsurface exploration to obtain information about the condition of soil layers below the surface of your project. Some of the methods we use to observe soil below the surface include obtaining samples, determining physical properties of soils and rocks with test pits, trenching, boring and in situ tests. We also use these methods to determine the presence of contamination prior to the start of a project, avoiding negative environmental impact.

Consulting Services, Inc. performs subsurface exploration to locate the water table and evaluate load bearing capacity, predict lateral earth pressures, determine type and depth of foundation, estimate settlements, forecast potential problems and establish construction methods. Groundwater seepage will impact all types of construction, maintenance and long-term performance of highways, hydrogeology projects and mining engineering. CSI will perform seepage analysis, assuring that this critical information is used in plan development.

At CSI we use both direct and indirect investigation methods on subsurface exploration. When we work with a client, we consider a range of factors while developing an investigation program that will best satisfy the needs of the project. Indirect investigation methods collect information without invading or penetrating ground surface through the use of:

  • Interpretation of aerial photographs

  • Review of geologic maps

  • Evaluation of groundwater contour and topographic maps

  • Searching for other published information

Direct investigation methods generally reveal a more detailed description of underground conditions through physically sampling or testing soil, rock and groundwater. Devices are inserted into a borehole, drilled into the ground, and samples are either returned to the surface for evaluation or the properties of the underground profile are measured in-place. Our drill team is fully credentialled, meeting the International Building Code requirements for “qualified personnel” who are on-site during all drilling and sampling: this includes both a driller and a geotechnical engineer. You can rely upon the accuracy of our boring sites as they are located with total-station technology. When you come to Consulting Services, Inc. for subsurface exploration, you can rest assured that our investigation will be thorough and accurate.

The expertise we have gathered at CSI is well-recognized and when you contact us, you will acknowledge that we have the capacity to work with your project from start to finish. If you have a question or want to discuss your project, give us a call in Lexington at (859)308-6021 or in Cincinnati at (513)252-2059. You will quickly realize that Consulting Services, Inc. is an engineering firm with a depth of experience that will serve you well on your next project.
