Services Performed:

• Pipeline and Utility Locating (Show/Hide)
  
  
  

  Possible Geophysical Tools: Ground Penetrating Radar, EM-61, EM-31, Radio Detection, Magnetometer

  For many industries it is vital to know what is below the surface before ground breaking activities take place.  It’s very dangerous to just assume an area is clear of obstacles and commence drilling or excavation activities.  Subsurface infrastructure damage is a huge liability issue for many of our clients.  EMC utilizes a multi-tool approach to locating and delineating subsurface pipelines and utilities.  We do not rely on a single geophysical tool but rather use an entire arsenal of equipment to provide the best possible information as to the location of underground lines.

• Void Detection and Delineation (Show/Hide)
  
  
  

  Possible Geophysical Tools: Ground Penetrating Radar, EM-31, EM-34, EM-38, Electrical Resistivity/IP Meter

  Subsurface voiding can be costly and dangerous.  EMC has conducted hundreds of void detection surveys for a wide variety of clients.  Whether you are conducting heavy lift crane operations in a petrochemical facility or have a suspected line break beneath a slab on grade, EMC can provide you with quality information to help you make safe and cost efficient decisions.   Our extensive experience with 3D modeling sets us apart from the competition.

• Underground Storage Tank/Tank-Hold Delineating (Show/Hide)
  
  
  

  Possible Geophysical Tools: Ground Penetrating Radar, EM-61, EM-31, Radio Detection, Magnetometer

  EMC has vast experience in locating Underground Storage Tanks (UST’s) under many different surfaces.  From steel reinforced concrete to asphalt or grass or gravel.  Once again we deploy a host of tools that can compliment and cross-confirm each other to enhance the confidence level.  Sometimes proving that a tank has been removed is just as important as proving that it is in situ.  By using the different tools and with our proprietary data processing techniques we can provide detailed maps indicating whether a UST is in place or if there is evidence of its removal.

• Contaminant Plume Delineation (Show/Hide)
  
  
  

  Possible Geophysical Tools: Ground Penetrating Radar, EM-31, EM-34, EM-38, Electrical Resistivity/IP Meter

  For a variety of contaminant plume situations, EMC has the equipment and the knowledge to get the job done.  Being headquartered in the Houston, Texas area EMC has been called on many times to locate and map chloride plumes from oil and gas producing areas.  We have also been instrumental in debunking claims of contamination through our comprehensive approach to site characterization.

• Core Drilling/Saw Cutting Concrete (Show/Hide)
  
  
  

  Possible Geophysical Tools: Ground Penetrating Radar, Radio Detection

  Ground Penetrating Radar (GPR) is a very safe and cost effective method to locate and mark rebar, post-tension cables, conduits and other elements located within concrete slabs prior to renovation work.  GPR is safe to use in close proximity to people.  3D imaging of structural steel can be produced quickly and images are easily included into reports for later reference.  In addition GPR is the only imaging technique for situations involving a slab on grade.

• P & A Well Locating (Show/Hide)
  
  
  

  Possible Geophysical Tools: Magnetometer, EM-61, EM-31

  Pinpointing the location of Plugged and Abandoned Oil Wells can save much time and money.  EMC has worked closely with many real estate developers, environmental companies and oil and gas producers to locate lost wellheads.  Unfortunately historical coordinates are often wrong and can be wrong by a significant margin.  EMC can quickly and efficiently locate these lost wellheads saving you much time, money and guesswork.

• Downhole/Crosshole Geophysics (Show/Hide)
  
  
  

  Possible Geophysical Tools: High Resolution Seismograph

  EMC has over 20 years of seismic acquisition and processing experience.  We utilize the most advanced techniques for determining velocities and site characteristics.  We’ve been involved in many engineering studies and can collect the necessary information for determining Poisson’s ratio.  EMC also has experience with MASW seismic acquisition which can provide valuable information through surface seismic acquisition.

• Vibration Monitoring (Show/Hide)
  
  
  

  Does your project have the potential to cause concern for the local community? Many construction, seismic and mining projects can generate vibrations that may not be harmful but can still be the genesis of legal action in our overly litigious society. Let EMC protect your interests by monitoring and recording the vibrations produced during your project.
  
  EMC can provide full reporting of all vibration activity recorded during the project thereby providing you with valuable information regarding vibration strength at specific locations throughout the course of the job.
  
  Don’t get caught in a situation where a little information can save you money as well as your good reputation as a responsible contractor. EMC has worked in all areas of the country as well as many international locations. Call us today to discuss your project and learn how we can provide you with confidence and peace of mind during your project.
