Due to the service nature, our analysts are fully aware of different on-the-job hazards and the safety procedures to be followed. Regardless of the project scope, we always come prepared and ready to take on the challenge.

CONCRETE REBAR GPR, X-RAY NDT TESTINGS.

Concrete rebar GPR X-Ray NDT testings are the non-destructive application of x-rays or gamma rays to image the interior of a concrete target to identify and locate rebar, conduit, post tension cables and other embedded objects. It is considered a branch of industrial NDT radiography testing. According to the EPA, radiography is useful when you want to avoid damaging the material being tested. Practically the most common targets for concrete x-ray are suspended slabs or concrete walls that may be renovated or retrofitted as part of a larger structure by cutting new openings.

Although cutting through rebar will weaken a structure it can often be achieved safely and within structural tolerance limits. Cutting through post tension cables poses more serious issues and is rarely deliberately executed. Likewise conduit should nearly always be avoided and accidental cuts can necessitate costly repairs, safety concerns and project slowdowns.

Concrete Rebar GPR X-ray is often considered superior to GPR (ground penetrating radar) for imaging the interior contents of a concrete slab due to the clarity and accuracy the image. X-rays are also inherently easier to interpret. However, in practical field applications, GPR is a more common approach. X-ray imaging will always require access to both sides of the concrete target – so a slab on grade concrete target cannot use x-ray at all. Learn More about the difference between the 2 services.

TAKING X-RAYS IMAGES OF CONCRETE & Steel X-ray Welds
A typical concrete x-ray set up requires 2 operators – one for the detector and one for the source. While capturing the concrete imaging, the 2 operators are on different floors – each making sure that the exclusion zone is clearly marked and no accidental intrusions occur. The detector is most often on the upper floor facing down while the x-ray source is below facing up, although an inverted setup is also possible. It is important to line up the detector with the source to ensure the emitted rays are directly striking the detector (perpendicular) and not coming from an angle. Complete remote control is possible, or the source operator will manually switch on the x-ray beam first (assuming a x-ray tube is used) and then call the detector operator to switch open the panel and take an image. When isotopes are used the source operator cranks out the isotope from its secure container exposing it the air and effectively firing gamma rays towards the detector.

COST OF CONCRETE X-RAY
Concrete rebar GPR testings are less expensive than XRAY due to its accuracy. The equipment is more expensive and a minimum of 2 operators is needed at all times. As a rule of thumb, concrete x-ray will cost double the hourly rate of GPR – although pricing by image may be more attractive for both parties. $150-$170 per image is fairly standard, combined with a mobilization charge of several hundred dollars. Night and weekend work is charged at 1.5 times standard rates which can lead to overtime rates too.

Protection from radiation is an important aspect of industrial radiography. The International Atomic Energy Authority (IAEA) had developed basic safety guidelines regarding the practice.
