A “Void”ing Danger

GPRS Project Manager Matthew Franklin scans with the GSSI SIR 4000 and 400 MHZ Radar to locate the full extent of the void.

GPRS Project Manager Matthew Franklin scans with the GSSI SIR 4000 and 400 MHZ Radar to locate the full extent of the void.

Underground voids can be extremely dangerous and can lead to severe property and personal damage. Recently GPRS was called to identify the extent of a void found within a subdivision in downtown Atlanta. The void was created by a leaking water pipe which washed out the soil under the slab, causing it to collapse in several areas. GPRS was asked to mark the boundaries of the void as well as scan for any other possible voids throughout the property.

Using the 400 MHZ Radar and the SIR 4000, GPRS was able to successfully identify the range of the known voids and how far they had spread unseen under the ground. Often, voids encompass a larger area than above ground identifiers, such as cracks in the concrete, would indicate. We were also able to detect other zones throughout the neighborhood that could contain possible voids.

Identifying areas of interest allows our clients to focus future investigations and efforts to solve the problem without having to waste time and money on exploring areas that are unaffected by voids. Ground penetrating radar is one of the best ways to identify voids as the process is noninvasive and does not rely on destructive techniques to produce results.

GPRS South Florida – Rebar Mapping at Hard Rock Stadium

Recently, the GPRS office, located in Miami Florida, was contacted by an electrical contractor that was completing a project at the Hard Rock Stadium located in Miami Gardens, Florida. This is also the home of the Miami Dolphins. This stadium recently underwent a five hundred-million-dollar renovation and work is continuing to be completed throughout the off-season at this facility. The GPRS team in South Florida has completed projects on this job site on several different occasions. This particular contractor was installing Wi-Fi hotspots throughout the stadium to help improve cell phone reception for its attendees. They contacted GPRS in order to locate any and all steel reinforcement in the areas that they planned on core drilling for their electrical conduits. It was very important to locate the steel within the slab in order to avoid compromising any of the structural integrity of the existing slab.

GPRS South Florida – Rebar Mapping at Hard Rock Stadium

For this particular project, the project manager pictured below is using GSSI’s (Geophysical Survey Systems, Inc.) SIR-3000, with their 1600 MHz antenna. With this equipment, he was able to identify the top and bottom layers of rebar located throughout the slab. A total of fifteen different areas were scanned, and steel was identified in each of these locations. With this information, the contractor was able to drill directly through the slab without damaging any of the reinforcement within the slab. In this particular case, no conduits were found to be within the areas scanned but this is oftentimes not the case. Our project managers are equipped with the knowledge and experience to identify any form of reinforcement within various concrete slabs, whether that be pan deck, rebar, post-tension cables or wire mesh. The use of our service can be applicable to many different types of projects.

Upon project completion, the company that contacted us for this project was extremely pleased with the result. Through effective communication and GPR knowledge, this project was completed without any issues.

Monitoring Wells – Las Vegas, NV

Monitoring wells are needed on a regular basis in order to test soil conditions below the surface. They can be necessary when selling property, when a hazardous material spill occurs, or for a number of different reasons. When installing or removing monitoring wells, it is important to know what utilities might be in the area. No matter what project is happening where digging is necessary, there are ways to keep yourself and your crew safer using underground utility location.

Monitoring Wells - Las Vegas, NV

Ground Penetrating Radar Systems (GPRS) was called recently to conduct underground utility locating around proposed monitoring wells that were to be removed near Phoenix, AZ.  Because these wells were installed by another company, the company that hired GPRS made the wise decision to have underground utility locating done prior to digging.

GPRS was able to identify utilities in the area where the digging was planned to occur. A 400 mHz antenna with the ground penetrating radar was used by GPRS to scan the areas as well as a Radio Detection wand which picks up most underground utilities with a current running through them.  All of the findings were clearly marked on the surface with spray paint and discussed with the customer. Whether working on removing monitoring wells, an older historic landmark, or a freshly built hospital and everything inbetween, Ground Penetrating Radar Systems can help.

GPRS is a private utility locator.  That means that GPRS can locate utilities where traditional “811” or Blue Stake services cannot go.  811 or Bluestake will only conduct underground utility locating on the public side of the respective utility’s meter and no futher.  GPRS can locate any and all utilties, whatever the need, wherever the location.

Prior to digging, saw cutting, core drilling, excavating or boring in Arizona, be safe and get as many questions answered as to what sub-surface obstructions are present.   This can include reinforcement or utilities within concrete or underground utilities.  If you have questions about what lies beneath whatever surface you’re working on, GPRS should be able to give you a much clearer picture as to what you are dealing with. Typically able to arrive on site to begin scanning within 1-2 days, GPRS will take care of your project in a timely, safe, and accurate manner.

Rebar detected with ground penetrating radar.

Rebar detected with ground penetrating radar.

Ground Penetrating Radar Systems, Inc. can identify obstructions embedded in concrete slabs such as post tensioned cables, rebar, plastic and metal conduits, beams, etc. Our technicians have the ability to identify an anomaly’s depth with the accuracy of plus or minus a half inch to the top of the anomaly itself. Moreover, we can detect the lateral position of the anomaly with an accuracy of plus or minus a quarter of an inch to the top center of the anomaly itself. This is important to note because there are often times a customer has to drill into the concrete to install anchors to a specific depth on both remodels and new construction projects. The obvious benefit of having such a high degree of accuracy is that the customer will have an indication of whether or not it is safe to drill.

GPRS, Inc. offers a response time unrivaled in the industry. Often times, we can schedule your project the same day or within a few days at the most. By delivering fast and accurate service, you can be sure your project remains on schedule and within budget.

Gone Fishing…

Gone Fishing1

Ground Penetrating Radar Systems (GPRS) was contacted by a fish hatchery in southern Illinois to come out and locate private and public utilities for running new communication lines underground. After scanning for a couple miles, we were able to confidently direct the electrical contractors away from hitting any utilities while trenching.

This particular fish hatchery has supplied over 500 million fish throughout its years of operation. Fish hatcheries in Illinois are also very important as they supply Lake Michigan and many other surrounding lakes with fish in order to keep up with the growing rate of recreational fishing.

Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can also provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans. This is all done in a safe, time efficient, non-destructive manner.

GPRS assists by giving a real-time depth view of subsurface hazards such as reinforcing, utilities, conduit, underground storage tanks, voids, etc. This reduces the likelihood of subsurface obstruction strikes during core drilling, saw cutting, trenching, soil boring, directional drilling, anchoring, and other sub-surface applications.

Ground Penetrating Radar Systems uses the GSSI (Geophysical Survey Systems, Inc.) Sir-4000 technology in locating. GPRS also uses the RD-8100 Locator to locate live power and radio frequency (RF) signals underground. We can also detect utilities in or under concrete via induction or conduction with an exposed or known surface utility line.
