Before drilling or concrete cutting can begin, certain steps must be taken by construction workers. In order to discover what is inside concrete before starting their work, they have certain options. Generally, the two most common choices are utilizing either concrete x-ray or Ground penetration radar (GPR) technologies. There are important pros and cons to each, and understanding these is critical when it comes to deciding on how to proceed. Read on to learn more about what makes them different and which are more beneficial for which kinds of jobs.
The Big Differences Between Concrete X-Ray and GPR
Concrete X-ray or radiography makes use of a radioactive source to produce images on film. In order for this process to be successful, access to both sides of a slab are necessary, for the imaging film on one side and the emitting source on the opposite side. Ground-Penetrating Radar, on the other hand, makes use of electromagnetic energy to penetrate concrete and return reflected signals that reveal the subsurface layout of a structure. GPR is far safer than X-ray, as it emits far less radiation. This technology emits about 1/100th the radiation level of an average cell phone.
The Pros And Cons Of Each
In general, GPR is most often the most efficient, cost-effective, and non-destructive concrete testing choice. It is also highly accurate, however in certain circumstances X-ray may be recommended for a more accurate picture. GPR is far more mobile and affordable, and offers access to real time results almost immediately. X-ray film, however, requires a more intensive set up and the film must often be developed off site. GPR offers a nearly unlimited coverage area and makes for high resolution imaging. However wet or extremely congested decks can scramble the signal and result in low visibility. While X-ray is less convenient and more time consuming, it simply offers the best quality imaging. If GPR does not work, concrete X-ray is guaranteed to get the job done.
