GPR Used to Locate Lines at Busch Gardens in Tampa, FL

In September of 2014, Ground Penetrating Radar Systems, Inc. (GPRS) was contacted by an amusement park in order to locate any anomalies such as electrical lines, water lines, septic lines, gas lines, fiber optic lines and other anomalies at their location in Tampa, FL. The contractor who was digging a trench to install new pipelines needed to make certain of where anomalies were in order to avoid hitting them while excavating their trench path. The company contacted GPRS of Tampa, Florida in order to know where the lines were located so they could dig their trench with less concern of hitting any of the anomalies in the area.

Justin Rasanow of GPRS was contacted in order to perform the survey at this location. Using our 400MHz antenna radar equipment and RD-7000, we were able to map out all of the anomalies which were running through the areas of concern as well as provide depths to the tops of the anomalies found. The amusement park and contractor working the job were pleased with our results and felt relieved that they could excavate the necessary areas.

Below is a photo taken on-site which depicts Justin Rasanow scanning an area of concern.

Reinforcement Locate at Sundance Ski Resort

Ground Penetrating Radar Systems was contacted by Cinnamon Creek Contractors to locate and draw out the rebar in a garage concrete slab. The contractor was required to determine if the concrete was strong enough to support the howitzer artillery cannon while firing to set off avalanche danger areas. The contractor needed GPRS to show the amount of rebar and the layout of the rebar to determine the strength of the concrete.

Ground Penetrating Radar Systems used a GSSI 1600 MHz antenna for this application to locate the reinforcement and conduits. All findings were marked directly on the concrete at the customer’s request for easy interpretation. GPR was ideal for this application due to the active work site in the surrounding areas. GPR emits no radiation and is safe for others to work in the area near the scan location.

Ground Penetrating Radar Scan to Locate Rebar and Conduit | Beverly Hills, CA

Ground Penetrating Radar Systems, Inc. – GPRS – of California was contacted by a construction company to locate and mark out rebar and conduit prior to core drilling in 5 different areas in the second floor of the Versace store in Beverly Hills, CA. Due to the client’s work schedule GPRS was asked to perform the work on a Friday night as they were to block off traffic. The slab consisted of metal decking and only rebar was found in the areas that they were to core drill. The use of Radio Detection also helped determine there was no conduit as there was no live power in any of the areas. The coring was in 2 framing locations and 2 areas along a wall as they will be installing plumbing for restrooms.

Geophysical mapping is a great tool to scan areas of post tension cables, rebar, and conduits, including PVC pipes and can also be used to locate underground utilities prior to digging or excavating.

GPR & Radio Detection Utilized to Locate Embedded Conduits in a Concrete Slab on Grade at a Retail Store in Ann Arbor, MI

Ann Arbor, MI1

Prior to saw cutting a concrete floor for the purpose of trenching to install new utilities, it’s imperative to have as much information as possible as to what is beneath the surface. There are precautionary measures that can be implemented to ensure existing utilities aren’t compromised during the saw cutting process. Ground Penetrating Radar & Radio Detection are excellent tools to utilize to investigate floors when performed by trained professionals.

Ann Arbor, MI2An electrical contractor had a project inside a retail store at a mall in Ann Arbor MI where they had to saw cut the floor in numerous locations throughout the space. The purpose was to install new electrical floor boxes throughout the space. Since the retail store was still in operation, it was essential that no existing utilities were compromised during the demolition process. The electrical contractor contacted Ground Penetrating Radar Systems of Michigan to scan the areas of proposed saw cutting to locate any sub-surface utilities. GPRS utilized a 1600 MHz high resolution antenna (GPR) & a radio detection device to perform the investigation. They were able to locate & mark numerous utilities passing through the proposed saw cutting areas. The GPR scan also allowed GPRS to provide a depth to the sub-surface utilities. The plumbing contractor now had the answers they needed to proceed with confidence.

Concrete Scan | The Woodlands, TX

Concrete Scan The Woodlands, TX

Ground Penetrating Radar Systems (GPRS) of the Houston, TX office was called by Windstone Partners to locate any obstructive reinforcement in the slab prior to repositioning the plumbing during a custom home remodel. Mitch Halquist, GPRS technician on site, used GPR (Ground Penetrating Radar) 1600 MHz antenna to locate and mark out the reinforcement in the slab such as post tension cables. In this photo, GPR found 2 cables right next to the existing plumbing fixture. With a simple precautionary phone call to GPRS prior to breaking ground, a hazard was safely avoided, and the drain was able to be exposed without any reinforcement hits.

GPRS is the safe, accurate, and effective method for locating reinforcement such as post-tension, pre-tension and rebar. This innovative technology has zero radiation and can assemble on site and scan and mark out in real time. The GPRS of Houston, TX covers Humble, Spring, Tomball, The Woodlands, Conroe, Cypress, Katy, Missouri City, Sugar Land, Pearland and Pasadena, TX.

Concrete Scanning for Rebar Mapping in Washington, DC

Concrete Scanning for Rebar Mapping in Washington, DCAn engineer out of Washington, D.C. called Ground Penetrating Radar Systems to locate the rebar within the structure. With the proper training we were able to distinguish between the rebar and conduits prior to drilling. GPRS was able to mark directly on the surface the depth and location of the reinforcing steel in real time. The engineer was in a time crunch and we were able to complete the request on the weekend. They also needed a company that had completed the OSHA 10 hour training course.   All of our technicians have completed the OSHA 10 training and are currently involved in an ongoing safety training course. Safety is a priority to us at Ground Penetrating Radar Systems and our thirteen year track record proves it.

GPR is a great tool to locate post tension cables. Ground Penetrating Radar Systems of Washington, D.C. scans for tension cables multiple times a week.
