But it is also predisposed to developing random cracks, which quickly become arteries for water, salts, chemicals and other foreign materials to seep in. Concrete is also porous, which leads to a number of problems, depending on the environment. In freeze-thaw weather cycles, water exerts tremendous force as it expands, leading to cracks and crumbling. Over time, this damage can cause serious and dangerous problems, including the collapse of structures like parking garages and bridge decks. A simple and effective way to address many of these concerns is with concrete coatings.

Revêtements en bétonIndex. décimale : 667.9 Revêtements et enduits Résumé : The practice of lining concrete substrates has increased exponentially over the last 30 years, most notably in the wastewater treatment industry. Environmental regulations, coupled with changes to treatment processes, have resulted in far more severe environments in which concrete can and will corrode.
Other than the floor coating field, very few contractors specialize in preparing and lining concrete structures, as carbon steel lining opportunities far outweigh those of concrete substrates. Accordingly, the majority of craft workers, both young and old, have far more training and experience preparing and lining steel substrates. It has been the author's observation that many of the aforementioned craft workers, and in many cases, management personnel, do not fully comprehend the difficulty and distinctions inherent to a concrete lining project.
A lack of understanding and experience extends beyond the contracting level. Many engineers, consultants, and inspectors do not fully comprehend the idiosyncrasies of lining concrete. When all the aforementioned parties converge upon a complex lining project, the potential for a perfect storm exists.
This article examines many of the common errors that often occur when concrete sub-strates are rehabilitated and offers practical solutions for prevention of said errors.
