Underground Utility Locating/Concrete Structure Scanning Specialists

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.

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

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

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.

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.

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.

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

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.

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.

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.

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

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.

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

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.

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.

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

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.

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.
