Vibration Services

By making sure the right vibration information is available to you at the right time, GeoSonics/Vibra-Tech helps you overcome your toughest challenges.

Vibration Monitoring

GeoSonics/Vibra-Tech vibration monitoring solutions give you the most thorough, reliable information available, enhancing your project’s success and easing neighbor concerns.

Ground vibration comes from many sources in the construction, mining and energy development industries – but no matter where it comes from, it can create concerns for equipment, structures or adjacent neighbors. When dealing with equipment, vibration levels may require monitoring and analysis to prevent damage. Where people are involved, there may be an even lower tolerance threshold to consider. GeoSonics/Vibra-Tech vibration monitoring services provide the solid technical information needed to assess such concerns and devise solutions.

Computers, electronics, manufacturing facilities, nanotechnology and similar sensitive equipment and structures require particularly special vibration monitoring and evaluation. GeoSonics/Vibra-Tech has specific range sensors to monitor vibration and noise below the threshold that humans feel, but which can still affect such equipment and structures. We have performed evaluations for locating nanotechnology research facilities and computer chip manufacturers. Our instrumentation has been used for isolation review for air conditioning, identification of vibration affecting hospital imaging systems, and much more. We can also prepare floor response studies and follow-up recommendations on structure modifications.

GeoSonics/Vibra-Tech vibration monitoring is also a critical tool to alleviate neighbor concerns and avoid or defend yourself against complaints. We use state-of-the-art instrumentation over and above standard blasting seismographs. Our capabilities far exceed others in the field, ensuring results of unassailable integrity. All of our units maintain the highest calibration evaluations and standards. When equipment works properly, no questions can be generated about the accuracy of the information, which also provides the basis for sound technical evaluations.

GeoSonics/Vibra-Tech’s principals have authored numerous publications related to vibration monitoring and have assisted in developing standards for communities in the monitoring and assessment of vibration. High qualifications, third-party objectivity and professional ethics are the key to our services and success. You can count on us to identify and solve your vibration-related problems.

Town Meetings

At GeoSonics/Vibra-Tech, we believe clear, concise and convincing communication is the foundation for building community trust.

In many cases, permitting for new operations or expanding existing operations requires zoning approval through local or state boards. During that process, questions are often raised about the activity at the operation and the effects on adjacent structures and communities. On issues like blasting side effects, structure response, vibration limitations, and more, the principals of GeoSonics/Vibra-Tech have the expertise, professional demeanor and industry respect and qualifications to get you through these evaluations successfully.

Our testimony experience ranges from drilling and blasting procedures to explosives and explosives safety, ground vibration and air overpressure, and general noise levels. Based on our firm’s history, our experts are able to provide solid, scientifically based testimony and address the concerns of everyone from individual property owners to high-level government officials.

Our noise evaluation testimony is well documented. With our background in noise measurement, modeling and contouring, we can provide the visual documentation that will make your case clear and convincing. We plan and present the evidence you need in a format easily understood by regulatory agencies.


GeoSonics/Vibra-Tech fully commits its people, expertise and technologies to provide reliable analysis and advice you can trust.

Vibration measurement is only one aspect of the monitoring process. Analysis of the results requires technical expertise to draw the proper conclusions from the data. GeoSonics/Vibra-Tech personnel have the experience to review vibration events, determine compliance and suggest courses of action when issues arise.

Simple analysis of blast recordings by third-party professionals can determine compliance. Further review determines and allows for assessment of correct seismograph operation and recording procedures. Evaluation of the records can indicate errors in recording time, assessment of overall levels and review of the waveform itself for blast issues. Analysis is also necessary to consider structural response. The review of the seismogram is the first step in complaint and structural response assessment of neighboring structures. Whether special instruments or multiple channel evaluation is necessary, GeoSonics/Vibra-Tech has the expertise to address your issues.

For blasting, special needs analysis of the delays within a pattern can be evaluated. Our Vibra-Map® delay selection program can be used to optimize timing within a blast pattern. This program can increase fragmentation with more efficient timing, reducing crusher throughput. Additional benefits allow for reduction of ground vibration. Overall reduction of peak particle velocities may result, in addition to modification of the ground vibration frequency. This can increase frequencies and reduce structure response.

Seismograph Record Certification

GeoSonics/Vibra-Tech helps you set the record straight and keep it that way when it comes to managing your compliance records.

Certification verifies that data records comply with state and local regulations, which is an important part of any monitoring or recording program. Records reviewed by our technicians are screened on a number of factors, including:

  • valid calibration check
  • recording accuracy
  • possible operator error
  • malfunctioning components

After investing time and money in your recording program to protect your operation, do not jeopardize your efforts. Our seismograph record certification will help to ensure the value of your investment.
