Repairing damage caused by corrosion costs billions of dollars annually. One significant contributor to the corrosion problem is decaying reinforcing steel bar (rebar), which causes staining, cracking, and spalling of concrete structures throughout...

HDG Reinforcing Steel
Reinforcing steel (rebar) is widely used in a variety of applications from bridges to reinforced buildings to enhance the tensile strength of the surrounding concrete. However, the addition of these strengthening elements can prove problematic for the structure if proper care is not taken to avoid corrosion. Because of the porous nature of concrete, moisture and road treatment chemicals can seep into the concrete, reaching the rebar within. When a project is constructed with a building material not able to survive its environment for the length of the design life, natural resources are needlessly consumed to continually repair and maintain the structure. In addition to the waste of natural resources, building structures that cannot sustain their environment can lead to hazardous situations. Accidents caused by corroded structures can lead to huge safety concerns, loss of life, resources, and more.
