Subsurface Interface Radar (SIR) uses electromagnetic signals to determine the location and existence of embedded objects in concrete and soil. Using 500 MHz, 900 MHz, and 1 GHz transducers, International Inspection can perform SIR inspections of concrete up to 24-inch in thickness and soil depths of up to 20 feet.
Concrete radar surveys are available for areas not accessible to x-ray, slabs on grade, retaining walls or concrete too thick to effectively inspect using x-ray techniques. Reinforcing steel can be precisely located even with spacing as little as 3 inches apart.
Since no radiation is required to perform a radar survey, this is an excellent alternative to x-raying in highly occupied facilities such as hotels, hospitals, airports, etc.
Note: International Inspection, Inc. highly recommends x-ray inspections over concrete radar inspections whenever possible. This is due to the fact that concrete radar techniques cannot differentiate between post-tensioned cables and rebar, whereas x-ray allows for the exact determination of concrete contents.
SIR can be utilized to locate buried objects such as pipes, tanks, and utility lines.
