Cracks – they aren’t all the same - There are many types of cracks that happen for many different reasons. They can be due to construction defects, job-site conditions, design problems, contractor error, environmental, change of use, concrete issues, shrinkage, etc. This presentation will cover 23 different types of cracks with plenty of photos and we will discuss the following for each type of crack: • How to identify them • What caused them • How they could have been prevented • How to repair them It will include the selection of materials and methods for structural, functional, and aesthetic crack repairs. Knowing all these things will help the specifier to not only specify the correct repair, but to reduce or eliminate similar cracking on future projects.
