Corrosion begins to affect a concrete structure’s integrity when its products (i.e. rust) occupy a greater volume than the original steel. This expansion creates tensile stresses in the concrete causing it to stain, crack, and spall. Cracks are a direct path for corrosive agents to reach the steel, and can develop to the point the functional service life is reached prematurely.

By the time the signs of damage become visible externally, the corrosion has reached an advanced stage. At this point, regardless of site location, rehabilitation costs will be expensive, and the repair process complicated. Therefore, water must be kept from penetrating the reinforced concrete and diverted from attacking the steel rebar within.


There are several statistics, trends, and implications related to whatsapp number database energy consumption and conservation that can be quite eye-opening.*

national energy bill for buildings is more than billion;
average household spends $1900 a year on energy;
improving energy efficiency by 50 percent has an annual value of $950 for the average household; and
during the nominal 75-year lifespan of a typical home, $950 a year in energy savings has a ‘present worth’ value of $18,500.
