When rebar corrodes it expands with enough force to cause cracking in the surrounding materials. This cracking can allow more access to moisture, which leads to more corrosion. Once the source of moisture has been removed, rebar will not continue to corrode. Detection and repair before the surrounding materials before they have lost all strength is essential. EnTech’s cutting edge Infrared – Energy Pattern Analysis and Ground Penetrating Radar technologies can detect corroded rebar before the damage is visible at the surface and before it is too late to make proper repairs.
