Why do we need to use your utility locating services if we already called “one-call”?

The One-Call service could be incomplete if utilities continue onto private properties and are outside of the public utilities jurisdiction. Identifying where the utilities come and go on your project site is your responsibility! With our professional underground utility survey, you have another safety measure against hitting underground utilities.

How do you locate underground utilities?

We use ground penetrating radar (GPR) and pipe/cable locators to locate underground utilities.

Can you find PVC and other non-metallic utilities?

While metallic utilities are easier to locate, we do locate PVC, fiber optic, concrete and other non-metallic pipes/cables as well.

What makes you different from other utility locating companies?

All of our technicians are trained to follow our proprietary "10-Step Utility Locating Protocol™". It has been tested on numerous projects, refined where required, and have successfully proven to minimize the potential for utility strikes. All this brings to our clients a service we believe is second to none. And - we’re very proud of that.

Is GPR scanning safe?

Unlike X-Ray, the typical EM radiation from GPR is less than what a cell phone emits. No special cautions or business interruptions are required.

Can you locate electrical conduits made of PVC?

While it’s easier to locate steel and other metallic conduits, we do locate PVC conduits as well. For locating electrical conduits, we use GPR as well as pipe/cable locators to minimize the risk.

Can you locate utilities below the concrete slab?

We locate utilities embedded in the concrete as well as those below the concrete slab.

What makes you different from other GPR concrete scanning companies?

All of our technicians are trained to follow our proprietary "10-Step Concrete Structure Scanning Protocol™". It has been tested on numerous projects, refined where required, and have successfully proven to minimize the potential for utility strikes. All this brings to our clients a service we believe is second to none. And - we’re very proud of that.

What are the typical methods/tools you use for geophysical services?

  • Ground Penetrating Radar (GPR) – Cart-mounted GPR and Concrete GPR
  • Precision Locating
  • Electromagnetic Induction (EMI)
  • Electrical Resistivity Imaging (ERI)
  • Seismic Refraction and Multi-channel Analysis of Surface Waves (MASW)

  • Very Low Frequency (VLF)

How does ground penetrating radar (GPR) work?

A GPR system works by sending an electromagnetic wave into the target material (earth, concrete, etc.) via an antenna. The reflective waves are then received in a time window reflecting the layers and conditions inside the material.

What is EM induction (EMI) and what’s difference between EMI and GPR?

EMI generates a primary magnetic field to induce an electrical current in the earth. A secondary magnetic field is generated by the current and measured. The characteristics of the measured magnetic field reflects the subsurface condition. While GPR can give detailed subsurface images, its investigation depth is very limited in silt or clay soils which are very common in the Tri-State area. EMI provides an alternate way of subsurface imaging where the GPR effectiveness is limited. An EMI instrument is typically used with a differential GPS for rapid subsurface mapping. Its survey speed is typically 5 times of GPR’s and it is very efficient for surveying large areas.

Do you do underground utility locating, too?

Yes. We do underground utility locating. Our utility mapping service can be used with or separated from our underground utility locating service.

Can you work based on PDF or image files instead of AutoCAD files?

Original AutoCAD files are preferred since it can provide the best resolution possible. Utility layouts based on these files are more accurate. However, we can still work on PDF or image files if original AutoCAD files are not available.

What underground objects can be detected through mapping other than utilities?

Underground storage tanks, drums, septic systems, oil/water separators, building foundations, cemetery burials, landfill boundaries, etc.

What are the advantages of subsurface mapping over GPR scanning?

While GPR scanning in reconnaissance mode can provide details of localized areas, it’s hard to grasp those aspects/anomalies of the survey area which were only apparent in a big scale. Subsurface mapping provides a map of the whole site for easy visualization to identify anomalies or characterize the site in a big scale. Subsurface mapping can also be much more efficient than GPR scanning, especially for large sites.

What causes water leaks?

Metal pipes corrode and deteriorate due to age or acidic soil conditions. Pipes, both metal and plastic, that are not so old can crack due to movement or misalignment stresses.

How do you locate water leaks?

We use advanced leak noise correlation computer systems as well as conventional acoustic listening devices.

I am not even sure where the water pipe is, can you still locate water leaks?

We can locate the water pipe for you first. All of our technicians are well trained in underground utility locating and well equipped to locate water pipes.

What makes you different from other water leak detection companies?

All of our technicians are trained to follow our proprietary "10-Step Water Leak Detection Protocol™". It has been tested on numerous projects, refined where required, and have successfully proven to reduce water leak costs for our clients. All this brings to our clients a service we believe is second to none. And - we’re very proud of that.
