Subsurface Mapping With Ground Penetrating Radar

Maintenance is a critical part for the health of any infrastructure, especially when

related to public safety. Massive structures such as Bridge, tunnels, dams etc. that

move and protect the masses need to be inspected on a regular basis not just for

structural and functional integrity but to keep the structures in perfect working

order and to slow deterioration in order to maintain safety and increase the

structures life span.

Prior to the technology being available bridges, parking garages, dams and other

parts of the infrastructure were inspected visually. In the case of bridge decks they

were inspected manually by dragging a chain across potential bad spots and

listening for changes in the sound. This is a method that is still used in inspections

today where various states department of transportation's have not yet modernized

or updated their inspection methods.

Ground Penetrating Radar [GPR] combined with expert interpretation software

provides the most comprehensive assessment for underground inspections.

Deterioration that occurs on a surface of the bridge like cracks or corrosions can be

easily spotted during the visual examination but the cracks, voids or corrosion that

occurs inside the layers of the surface cannot be seen until a sample is taken out

(coring) and examined in the lab. This method is time-consuming and it further

increases the internal damage and exposes the bridge deck to the elements which

could further deterioration.

This problem has been solved by the introduction of a nondestructive and non-

invasive technique known as BridgeScan® BridgeScan was developed by IPC as a

method that incorporates “Ground Penetrating Radar” to assess below the


BridgeScan® scans the subsurface layers to find anomolys that if repaired can help

extend the service life of important infrastructure assets. It images below

subsurface layers to locate delamination, debonding, rebar placement, concrete

thickness, voids, water intrusions and more.

This technology utilizes radio waves to locate the underground abnormalities and

interpretation software based on hundreds of past inspections to report on not only

existing issues but issues that can become problems in the future. The best part is

that it can work on any kind of surface whether it is concrete and even non-

concrete surfaces.

infrastructure preservation corporation

Infrastructure Preservation Corporation (IPC) is a trusted name in bridge

inspection and our advanced underground utility locating systems are operated by a

team of highly trained and certified technicians. The Ground Penetrating Radar

(GPR) system can locate reinforcing steel/rebar, electrical conduit, post tension

cables, and PVC pipes inside the earth’s surface.

The indications on surfaces mapped by the GPR can be used to prevent structural

damaging mistake prior to coring, construction or drilling. We offer a wide variety of

GPR services to bridge owners and construction companies. We are committed to

using safe, nondestructive inspection services. GPR is completely safe and presents

no risk to the inspection crew, unlike concrete X-ray inspection which poses

radiation threat.

IPC’s underground utility inspection system produces results quickly and

accurately. The result can even be seen in real time and stored for later analysis.
