Things have progressed from combing the beach with a device that looked like it came from outer space looking for change to using a rebar detector to help save potential hazard, both physical and financial. Quite a progression indeed.
When it comes to construction, rebar reinforcement is the norm. And repair or restructuring brings on potential problems like structural weakening or accidental damage. A rebar detector might not find your change under your beach towel but it will tell you where rebar are located under concrete. It can also be extended to find mild or stainless steel or galvanised wall ties. It is essential to the process of properly installing rebar.
Digital technology has allowed for a rebar detector to tell you what’s inside the concrete bed of a structure and where, distinguish between horizontal and vertical bars, determine the concrete cover, and with an audible signal on exact discovery. And most rebar detectors are unaffected by temperature changes, moisture exposure or electrical interference, making the signal and alert that much more precise.
A device like a rebar detector can tell us many things on a larger scale. How fast different kinds of rebar are affected by environmental or chemical exposure for example, or structural shifting over time, or more succinct, where a structural problem is without risking over-wear or extra stress on the building itself. It is amazing how a tool like this can have the power to potentially save a life.
The need for technological improvements is obvious and ongoing. And tools like these are fascinating and multi-functional. For a job on any scale, quality control on a construction in progress, problem solving in a repair or reconstruction, or even long term research and development, a device like a rebar detector is indispensable.
