Concrete is a cornerstone material for any construction project, whether it’s the pavements around you, the offices, or the fancy skyscrapers! It doesn’t take a particular professional to tell you that! 

While concrete is a relatively common, easily managed, and everyday substance, if it is not done correctly, it can cause severe problems. Proper concreting guarantees that projects are not only durable but also have the needed strength.

A few frequent concrete difficulties can be caused by improper methods and maintenance, as well as particular weather conditions, and can damage the aesthetics and durability of the structure. Fortunately, the majority of these typical concrete issues have remedies.

In this webinar, Engr. Grace Amarles, Technical Services Officer of Holcim Philippines, Inc., discussed common concrete problems that one might encounter and proper ways to troubleshoot or prevent them.
