When designed and applied correctly, concrete structures can withstand substantial loads and last for decades with minimal maintenance. Cracks in concrete are common but some cracks can lead to major structural issues if not addressed.

To discover the differences between minor and major concrete cracks, Host Joe Shuffleton speaks with Registered Engineer Dylan St. Leger. During Dylan’s career at ETC, he has inspected hundreds of buildings with concrete cracks and designed restoration projects for parking garages, balconies, and related concrete structures.

During this discussion, Dylan identifies the common underlying reasons for cracks in reinforced concrete, the cracks that can compromise structural integrity, and simple methods to repair minor cracks.
