ENGINEERING SERVICES
Geotechnical engineering is concerned with the engineering properties of earth materials. Our staff of highly educated, professional engineers are ready to assist the client in determining a site’s engineering properties and how those properties will interact with the proposed construction.
A geotechnical investigation by one of our experienced engineers will include obtaining information on the physical characteristics of the soil and rock to provide recommendations for earthworks and designs of foundations for the project. Our three fully equipped drill rigs and skilled crews are available to assist, if necessary, with the site investigation to obtain sampling of the subsurface conditions. GeoTechnologies’ engineering services also include dam evaluations, retaining wall design, and Phase I environmental evaluations, to name a few. Our staff is trained in the use of the Marchetti Flat Plate Dilatometer (DMT) which is used for estimating settlement on heavier structures. We also utilize other sophisticated equipment to provide geophysical refraction testing, field resistivity and GPS locating of soil borings.
GeoTechnologies takes pride in providing innovative, economical solutions to engineering problems. Most of our engineering staff has Masters or Doctoral degrees. They have taken on the challenges of projects such as NCEMC Peak Power Plant in Anson County, North Carolina to the LNG Storage Tanks in the Fujian Province of China. Big or small, all of our projects receive the same quality attention that keeps our clients returning for assistance on their other projects.

CONSTRUCTION MATERIALS TESTING
GeoTechnologies, Inc., provides quality assurance and observation of construction materials placement during the construction phase of a project. Depending on the size and complexity of the job, our skilled technicians can provide continuous or periodic inspections.
Our trained field technicians have extensive experience in the testing of concrete, asphalt and other construction materials, as well as in the evaluation of construction materials after they are in place. Our field technicians are equipped to perform necessary field tests and are highly capable of resolving problems which may arise during the actual construction sequence. If necessary, they will provide recommendations for achieving required compaction percentages, repair of unsuitable areas during construction, as well as providing information regarding potential problems which may arise before and after construction is complete.
GeoTechnologies provides all field technicians training at ACI (American Concrete Institute) for certification in concrete field testing. Many of our technicians are NICET (National Institute for Certification of Engineering Technicians) certified and are continually seeking higher certification in the areas of soil, concrete and asphalt testing and inspection. All field equipment used by our staff is routinely calibrated and tested for optimum performance.
GeoTechnologies also offers services utilizing specialty equipment including:
- Windsor Probe
- Nuclear Density Gauges
- Dip Stick (Floor Flatness Measurement)
- Seismographs
- Pressure Meter
DRILLING SERVICES
GeoTechnologies, Inc. provides in-house drilling services to support our engineering staff during geotechnical investigations.
We utilize three all terrain, vehicle mounted drill rigs which are run by our technically trained crews. Our lead operators have over 50 years combined experience in subsurface exploration and can provide timely mobilization of a rig and crew to the project site.
LABORATORY TESTING SERVICES
GeoTechnologies, Inc. offers full service in-house laboratory testing of soil, concrete, and asphalt. All tests are performed in accordance within the appropriate ASTM or AASHTO standards.
GeoTechnologies is committed to a high level of quality control by ensuring that our laboratory staff is properly trained and our testing equipment is properly maintained and calibrated. Our clients can be assured that their test results will be reliable, accurate, and performed in a timely manner.
