GPRS Uses Ground Penetrating Radar To Expand Business

By GSSI
Many early adopters of ground penetrating radar (GPR) technology found concrete scanning to be the effective application. Those anchoring, saw cutting, or core drilling concrete would hire a contractor to scan the area before cutting to avoid accidentally hitting an object. For this reason, construction firms have come around to the notion that concrete scanning is vital to job site safety and efficiency.

Solutions For Supporting The Aging U.S. Utility Infrastructure

By Concrete Openings
Much has been studied, analyzed and written about as it relates to the aging U.S. infrastructure over the last several years. While we can't pretend we have the expertise to add high-level studies, data or information to the ongoing conversation regarding infrastructure, we do want to provide a unique perspective from an industry contractor who supports the efforts to maintain, upgrade and replace that infrastructure.

Industry Insights

Accurate & Comprehensive Locates

When calling for a utility locate, it is essential to locate a company that specializes in providing both a public and private locate. The “call before” you dig system is a great tool to use when needing a locate in a public right of way. When a locate is needed on private property, the “one-call” system should still be utilized but the private property locate is not complete until a private locator has located all of the utilities.

What is GPR?

GPR (Ground Penetrating Radar) is a general term for a collection of devices used to locate objects within materials, typically in applications where visual inspection is impractical. GPR is often used to locate underground objects, but it’s also used on manmade structures. Its basic operation is to emit and receive the signals that reflect off of subsurface objects. GPRS uses GPR to scan concrete for objects such as rebar, or to locate utilities. GPRS does not use GPR for geophysical or geological purposes. Use of a GPR in conjunction with other devices can provide reliable information to prevent injuries or costly downtime on construction sites, among other uses for GPR.

What does an underground utility locator do?

Subsurface utilities and other buried materials are often considered low priority when it comes to construction and excavation work. Yet locating them is one of the most important aspects of creating a safe work environment, and allowing work to continue on time and on schedule.

Difference between Concrete X-ray and Concrete Scanning

When it comes to finding out what’s inside a concrete slab, non-destructive options are generally the first choice. The two main options are the use of x-rays or ground penetrating radar (GPR) to “see into” the concrete slab or structure. Both provide a closer look at what’s inside, including rebar, conduit, post-tension cables, and more.

Utility Locating Prior to Soil Boring

Often times when a property changes hands, there can be a question about the environmental condition of the soil. Before the purchase or transaction, buyers look to avoid liability for existing environmental conditions by performing different methods of “due diligence”. Soil borings are often performed to investigate underground soil conditions of a facility where there has been contamination by hazardous materials or waste.

Using Video Pipe Inspection

Video Pipe Inspection is a method of visually inspecting a utility line to detect cracks, infractions, blockages, and other imperfections in the line. The process involves navigating a camera through the line, either manually or via a remote control, which provides a video feed of the pipe interior to an on-site monitor for viewing.

The Lateral Launch

Lateral Launch is another variation of our robotic crawlers. The lateral launch system is similar to a standard robotic crawler, but it has a mechanical push camera attached that can be launched into the laterals from the main line. Lateral launch fills the gap where there are laterals off the main line that crawlers or push cameras cannot inspect alone.

What to Know About 811

It is critical to call 811 before you dig. This process usually starts a few days before you plan to start a new project. The 811 phone number is a toll free nationwide number and should always be called before starting any type of digging project. Be sure to look at your own state laws because most require two to three business days before excavating.

Locating Buried Electrical Lines

Buried electrical lines may run alongside buried fiber and other cables, complicating the process of identifying them.
While the majority of electrical lines are found above ground in the United States, there is still a percentage of lines which have been buried below ground. These lines often run from a public box or meter on to private property. As a result they are out of the domain of public utility locating companies such as 811. Buried electrical lines may run alongside buried fiber and other cables, complicating the process of identifying them.

Locating Sewer Lines

Sewer lines are a key utility but are often overlooked by public and even private utility locating services. Lines can be made of a variety of materials, depending on their age and location. The majority of sewer piping material is non-conductive- materials such as HDPE, PVC and even clay are all commonly used. Lines can be decades old, meaning that accurate plans and as-builts are often missing or non-existent.

Locating Water Lines

Ground penetrating radar is capable of finding all types of material regardless of conductivity.
Water lines can be made out of various types of material, not all of which are conductive. Traditional methods of utility locating are only able to pick up on conductive materials. This leaves PVC and other non-conductive materials beyond the scope of many utility locating services. Ground penetrating radar is capable of finding all types of material regardless of conductivity. This makes it an excellent choice for locating buried water lines.

This leaves you with the dangerous potential of hitting any private utilities they failed to locate. Calling a private utility locating service in addition to 811 will ensure you uncover all buried utilities before digging or working in an area.
